Executive Summary: Resolving a Legacy NVIDIA Workstation on Linux Mint 22.3

After extensive troubleshooting of a Dell Precision 5810 workstation equipped with an NVIDIA Quadro K6000, Linux Mint 22.3, and the legacy NVIDIA 470 driver branch, the system has been restored to a stable and fully accelerated state.

Initial Problem

The workstation intermittently fell back to:

llvmpipe software rendering
nouveau fallback drivers
loss of hardware acceleration
inability of nvidia-smi to communicate with the GPU

These symptoms initially resembled common Linux graphics issues such as incorrect GRUB parameters (nomodeset) or driver corruption.

Root Cause

Investigation ultimately revealed that Secure Boot had been re-enabled in the system BIOS.

This prevented the proprietary NVIDIA 470 kernel module from loading correctly, causing the system to fall back to software rendering (llvmpipe) and open-source graphics drivers.

After disabling Secure Boot:

NVIDIA proprietary drivers loaded correctly
CUDA became available again
OpenGL hardware acceleration was restored
Firefox and Cinnamon resumed GPU acceleration
nvidia-smi reported normal operation

Current System Status

The workstation is now operating correctly:

NVIDIA Driver 470.256.02 active
CUDA 11.4 functional
OpenGL hardware acceleration functional
Firefox GPU acceleration active
Xorg using NVIDIA hardware
Stable temperatures (~44°C idle)
No nouveau fallback
No llvmpipe rendering
No Xid errors or GPU instability

Current idle state:

GPU: Quadro K6000
Temperature: 44°C
Power: 22W
GPU Utilization: 0%
Memory Usage: 499 MiB / 12 GiB
Performance State: P8

The system can now be considered production-ready.

Remaining Observation: PCIe Gen1 Link Speed

One unresolved observation remains:

LnkSta: Speed 2.5GT/s (downgraded), Width x16

and:

PCIe Generation
Max: 3
Current: 1

This indicates that the GPU is operating at PCIe Gen1 speeds while retaining the full x16 lane width.

Why This Is Not Considered Critical

Despite the reported Gen1 link speed:

OpenGL benchmarks (glmark2) produce strong results
Rendering remains smooth
CUDA operates correctly
No evidence of bandwidth starvation exists
No instability or graphical corruption is present

This suggests the issue is likely related to:

Dell workstation firmware behavior
Kepler-era GPU negotiation quirks
Legacy NVIDIA 470 driver reporting behavior
Conservative PCIe compatibility policies

rather than a genuine hardware fault.

Lessons Learned

Several important engineering principles emerged from this investigation:

Symptoms are not causes.

Both Secure Boot conflicts and GRUB nomodeset configurations can produce identical symptoms such as llvmpipe, despite entirely different root causes.
Always verify driver status before diagnosing performance.

When llvmpipe appears, the primary question is not "Why is OpenGL slow?" but rather "Why is the real GPU driver not loading?"
Enterprise hardware prioritizes stability over peak performance.

Dell workstation firmware often favors conservative behavior, particularly when older GPUs interact with modern kernels and firmware.
A stable system is often more valuable than a theoretically perfect system.

Once:
- performance is good,
- temperatures are healthy,
- acceleration works,
- workloads complete successfully,
further optimization can introduce more risk than benefit.

Final Assessment

The workstation has successfully transitioned from an unstable software-rendered state to a fully accelerated and reliable Linux production environment.

The remaining PCIe Gen1 behavior is best categorized as an interesting firmware-level research topic rather than an operational defect.

In engineering, one of the most valuable skills is recognizing the difference between:

a system that is broken

and

a system that is simply not behaving exactly as expected.

At present, this Dell Precision 5810 clearly belongs in the second category. The machine is stable, performant, and ready for real work. After several days of debugging Secure Boot, NVIDIA drivers, PCIe negotiation, and rendering stacks, that outcome should be regarded as a success.

Superuser prompt pops up 4 times (!)

https://askubuntu.com/questions/1567316/superuser-prompt-pops-up-4-times

I recently upgraded to Ubuntu 26.04 LTS. I used to use a VPN app, which now shows 4 times prompts for the superuser (after the upgrade) - on the last Ubuntu version I had not a single prompt when establishing a connection. What can I do to simplify this behaviour?

Pycharm kivy not found when it is installed kubuntu 24.04

https://askubuntu.com/questions/1567315/pycharm-kivy-not-found-when-it-is-installed-kubuntu-24-04

I made a mistake and had a space in my project file name. I renamed it and made a new virtual environment and python interpreter. Now whenever I run my scripts I get the error:

[WARNING]: prerequisites.py is experimental and does not support all prerequisites yet.
[WARNING]: Please report any issues to the python-for-android issue tracker.
Traceback (most recent call last):
  File "/home/jahil/Desktop/0python/gymtracker/test.py", line 2, in <module>
    from kivy.app import App
ModuleNotFoundError: No module named 'kivy.app'

Process finished with exit code 1

I found an old thread about how filenames containing kivy can break the extension so I've already renamed all my files, but it still persists. I've tried restarting my pc and reinstalling kivy. I've provided a screenshot of my set up and you can see it is installed. Any suggestions on what I can try to resolve this?

Partition doesn't show the right size during installation

https://askubuntu.com/questions/1567313/partition-doesnt-show-the-right-size-during-installation

I'm new to Ubuntu and Linux as a whole. I wanted to try dual-booting on my laptop with Windows 11 and Ubuntu Server. I created unallocated space for Ubuntu in Disk Management on Windows (about 120gb) but during the installation process it showed the partition as only having 16mb. I did check the other partitions but they seemed to line up perfectly with what I saw in Disk Management. It's only the unallocated space that's not shown correctly (the unallocated space on my SD card doesn't even show at all but that's not a problem). Right now there should be 6 partitions. Partition 1,4,5,6 are small/recovery partitions that were already on the laptop when I bought it. Partition 2 is my Windows partition and 3 is the empty space for Ubuntu (2 and 3 are switched in the Ubuntu install). Should I just install it on the empty partition then? This is what is shown during installation, This is what Disk Management shows

Ubuntu laptop inconsistent booting, freezes, screen with blue pixels

https://askubuntu.com/questions/1567312/ubuntu-laptop-inconsistent-booting-freezes-screen-with-blue-pixels

I am no expert in Ubuntu so I would really appreciate some help. Randomly, my laptop (hp with amd ryzen and nvidia GeForce gtx1650, specifically ho pavilion 15-ec2013ns) showed some weird pixels (boxes where 3 squares are black, 1 white etc). Sometimes it boots, sometimes it doesn't, sometimes it goes to grub. When it boots it might work or freeze. If I move the screen or the laptop, it might freeze... I checked the logs and there were some ACPI errors (there are other errors too):

I couldn't understand anything (numbers, "words" that I don't understand e.g. RAX: then numbers). The only sentence I saw was: systemd-journal[370] exited with irqs disabled

Please help me debug this...I don't know what is going on since a couple days ago it worked perfectly...

Thank you so much for any answers!

How to convert an animated svg to gif in Ubuntu?

RTL8723de or RTL88x2B USB drivers for Ubuntu 26.04 LTS

https://askubuntu.com/questions/1567309/rtl8723de-or-rtl88x2b-usb-drivers-for-ubuntu-26-04-lts

I am experiencing persistent issues with the Realtek RTL8723DE WiFi driver on Ubuntu 26.04 LTS. The main problems are that the wireless signal is very slow, and after suspending the laptop, the WiFi adapter stops working entirely—no networks are detected until a reboot.

I have tried installing multiple drivers, including different versions and community-supported alternatives, but none have resolved the issue. I also configured the system to prevent the WiFi adapter from being disabled during suspension, but this did not help.

Additionally, I downgraded to Ubuntu 22.04 LTS to test compatibility with an older kernel version, but the problem persisted. As a potential hardware solution, I researched replacing the internal WiFi card with an Intel model. However, based on available information, Intel cards are not compatible with my laptop model (HP 14-dq1003la).

As an alternative, I considered purchasing a USB WiFi adapter, specifically the TP-Link Archer T3U Nano (RTL88x2B USB). However, I found reports indicating that it may also have similar driver or compatibility issues on Linux systems.

What can I do in this situation?

Cursor keeps jumping to top right of monitor randomly - Ubuntu 20.04.6LTS

https://askubuntu.com/questions/1567307/cursor-keeps-jumping-to-top-right-of-monitor-randomly-ubuntu-20-04-6lts

My cursor keeps randomly jumping to the top right of whichever monitor the cursor is on. This is rendering my PC inoperable when the behaviour is occurring as I am constantly accidentally closing windows when the cursor jumps just before I click. Sometimes it goes long periods without happening, restarting doesn't affect the behaviour, and it seems to be very random.

This happens with 2 wireless mice, a wired mouse, and just the touchpad
This happens when I have a mouse and disable the touchpad via settings
Running Ubuntu 20.04.6 LTS
Laptop: Dell Precision 7760, dual boot with Windows 10, with fast boot/fast power-up switched off
Laptop has no touchscreen or touch stick

As a separate but possibly related issue, my cursor often disappears entirely (but I can still see that the mouse movements are highlighting buttons etc.), and only reappears once I've pressed the windows keys which brings up the option to switch between windows.

Thanks in advance for any suggestions :)

My Ubuntu 24.04 broke after an update, I have to reinstall. In the past, it was possible during the installation to keep the datas in the /home folder. It know that it wasn't the case for version 24.04 and 24.10

I hope this feature exist again in version 26.04, but I didn't find it...

Ubuntu 26.04 dracut network configuration

https://askubuntu.com/questions/1567304/ubuntu-26-04-dracut-network-configuration

I'm fighting with this for a week. Read and searched a lot, That's why I decided to post my first question.

Initial setup :

Windows AD Network. Windows DHCP Servers automatically update DNS. Install Ubuntu server on Hyper-V virtual machine. This time I decide to give a shot for 26.04 LTS. Ubuntu server is with static IP address, which I define during installation process. Let's say I gave it name svr-2604 as a host name and IP: 192.168.100.100/24 gateway: 192.168.100.1 Installation went smooth exactly as it was in 24.04 LTS that I used till that moment. After installation I checked IP:192.168.100.100 and it was there. I get terminal SSH and everything was as expected. I create static record in DNS with name svr-2604 pointing to 192.168.100.100 (my usual action). I could ping and connect by terminal to SSh using this name (also as usual).

Restart Ubuntu server and for some reason I flush DNS cache on my computer. At that point I try to connect with terminal using the same name - without success. Check server - running. Ping name - no response but returning address completely different from DHCP range. Check DHCP and figure-out fresh address lease on name svr-2604 with address (let say): 192.168.100.36. IN DNS I have already two records about my server : 192.168.100.36 - dynamic from DHCP 192.168.100.100 - static

On request DNS returns first one and I can't connect to server by name.

On Ubuntu I checked log records :

journalctl | grep -i dhcp

get

svr-2604 systemd-networkd[420]: eth0: DHCPv4 address 192.168.100.36/24, gateway 192.168.100.1 acquired from 192.168.110.XXX (my dhcp server)

Check for configuration in /run/systemd/network and there I get :

-rw-r----- 1 root root             78 May 29 09:41 10-netplan-eth0.link
-rw-r----- 1 root systemd-network 222 May 29 09:41 10-netplan-eth0.network
-rw-r--r-- 1 root root            131 Apr 13 13:34 zzzz-dracut-default.network

First two are clear - result from my static address netplan configuration, but zzzz-dracut-default.network ??

Start digging and figure-out it was dynamic generated from dracut. It's content :

[Match]
Kind=!*
Type=!loopback

[Network]
DHCP=yes

[DHCPv4]
ClientIdentifier=mac
RequestOptions=17

[DHCPv6]
RequestOptions=59 60

In my opinion, this is where my problem comes. dracut on boot process leased address with my server name. When Ubuntu 26.04 boots - it takes configuration from netplan (the one that I wish to) but I finish with two different records in DNS.

What I try is to set dracut to use static address. I ended with idea that I have to give kernel command for this. Create following file : /etc/dracut.conf.d/network.conf

with following content :

kernel_cmdline="ip=192.168.100.100::192.168.100.1:24::eth0:none"

after that I regenerate image with

dracut --force and reboot

Sadly no result. At that point I gave up and decide to ask for help. This never happens with Ubuntu 24.04 or earlier.

What is may positive move to resolve this problem ?

Any help is appreciate !

Regards

GlobalProtect VPN is not connecting in Ubuntu 24.04

absurd system instability & Maximum number of clients reached

https://askubuntu.com/questions/1567300/absurd-system-instability-maximum-number-of-clients-reached

I am seeing a resurgence of this issue...from 15 years ago: How can I diagnose/debug "maximum number of clients reached" X errors?

The symptoms are despite not being heavily loaded or up for any length of time the following happens:

applications and context menus will simply not happen
after closing some arbitrary window the previous application/context menu will work
occasionally i was getting a notification about Maximum number of clients reached, which was absurd given:
- after an nvidia update basically hosed itself, I had manually rolled back my OS to it's prior state and disabled all updates - this may have been imperfect but definately worked fine for several weeks/months PRIOR to the issue of this post.
- at no time did I update anything that correlated with the change in behavior, except Discord
  - lsof -U +c 15 | cut -f1 -d' ' | sort | uniq -c | sort -rn | head -3 certainly doesnt seem like it should be an issue
- the only other thing that could possibly have made any changes are some AI mods that i installed for Valheim via valheim.thunderstore.io (which i'm only mentioning for completeness)
- on 24.10 i followed some variations of the advice here: https://unix.stackexchange.com/a/714487 - to no effect. It is an X11/nvidia/pulseaudio system.
- on 26.04 i accepted the notifications suggestion to do the same as the above: increase maxclients - to no effect, but i didnt check what it actually did. It is an X11/nvidia/pipewire system.

Attempting to reinstall 24.10 and terminate its upgrades prior to the nvidia fiasco is still on the table. Despite being quite possibly a lot more hassle.

So far I'm tolerating it on 26.04 by needing to reboot once a day or more, while I investigate adapting all of my scripts etc to 26.04 (pipewire and X11). But neither of my OS partitions are really useful platforms because of this problem.

Switching to wayland is not an option at this time; due to their dependence on functionality supplied by xdotool|xprop|wmctrl|etc almost all of the audio/video/convenience scripts i rely on to stay sane are unsupportable by wayland, and anathema to the current wayland philosophy of ?sandboxing? windows, as far as i understand it so far.

Do I have A.I./linux-vulnerability koodies? Or is the primary LTS release just a lot jankier than usual?

Constant audio output changes lead to disruptive "Select Audio Device" OSD

https://askubuntu.com/questions/1567297/constant-audio-output-changes-lead-to-disruptive-select-audio-device-osd

I'm on the latest Ubuntu 26.04 fully patched and having audio issues.

What I think is going on is:

The snd_hda_intel driver seems to have a hard time reliably detecting my sound hardware
This results in Linux thinking that my sound hardware keeps changing
Which results in Ubuntu trying to keep up - with sometimes hundreds of changes per minute visible in the sound widget (top right corner of screen) and
Frequent On Screen Display (OSD) asking me to "Select Audio Device", which are blocking and disrupt whatever else I'm doing.

Here is what I can see in dmesg:

$ sudo dmesg | grep snd_hda

dmesg is FULL of "spurious response" messages - hundreds and hundreds of them.

$ cat /proc/asound/card*/codec\#*|grep -i codec
Codec: Realtek ALC3226
Codec: Nvidia GPU 42 HDMI/DP

I have read How to disable 'Select Audio Device' popup when plugging in a device and installed the suggested GNOME plugin but it has made no difference. I am NOT plugging in a new device or changing anything when this behaviour happens. It happens when I'm reading my emails, or when the system is completely idle. I can't connect this behaviour to anything I do, as a user of the system.

Sometimes, this issue is not visible for an entire day - no OSD popup. Other times, it completely blocks my ability to use the system, as I get OSD popups every few seconds, making my system completely unusable.

Here is the start of dmesg that shows you the kind of hardware I'm on (an old Dell Precision M4800 laptop):

Would very much appreciate any guidance on how to troubleshoot this, report this as a bug, or find workarounds that make my Ubuntu system reliably usable. If there is a way to disable the sound system completely when I don't need it, only to be re-enabled later, I'll happily use that as a short term workaround.

Several questions regarding dual boot system, Fast Boot and Secure Boot, etc

https://askubuntu.com/questions/1567296/several-questions-regarding-dual-boot-system-fast-boot-and-secure-boot-etc

I have a dual boot system with Ubuntu 26.04 LTS and Windows 11 installed on my Galaxy Book 2 Pro 5G. Fast Boot and Secure Boot were disabled during the installation process. When and under what circumstances can I enable them, or what can't I enable them? (I only have one SSD with one NTFS shared partition, that's all.)

enter image description here ^{My SSD}

My second question is, if I remove Ubuntu from the dual boot system and reinstall it, do I need to modify GRUB or any other settings?

My third question is, the ESP partition is currently about 200MB. What are the benefits of increasing it to 500MB or more for a dual boot system, such as speeding up Ubuntu's boot time?

Delayed boot in Ubuntu 24.04: Black screen with 'X' cursor for 1 minute before desktop loads

https://askubuntu.com/questions/1567293/delayed-boot-in-ubuntu-24-04-black-screen-with-x-cursor-for-1-minute-before-d

System Details:

OS: Ubuntu 24.04 LTS

Hardware: Dell Inspiron N4010

Problem Description: I am experiencing a very slow and glitchy boot process on my new Ubuntu installation. The boot sequence does not transition smoothly and behaves like this:

A stretched/wide Ubuntu logo appears first.
It then abruptly switches to the normal-sized Ubuntu logo.
Right when the login screen or desktop should appear, the screen goes completely black.
A cross/X-shaped mouse pointer appears on this black screen.Why is the desktop environment hanging with an 'X' cursor instead of booting directly, and how can I fix this to get a normal, seamless boot experience? Any help with diagnosing the boot logs or fixing the display manager would be appreciated!
The system hangs in this state for about 1 minute.
Finally, the wallpaper and desktop environment load, and the apps start appearing.

Unable to connect mouse

https://askubuntu.com/questions/1567291/unable-to-connect-mouse

I am on 26.04 and am having troubles attaching a mouse either through Bluetooth or Wi-Fi. When I first installed it, I had a mouse and my hearing aids working through Bluetooth, but the last couple of days nothing works. I have tried connecting a mouse through a transmitter, but I've had no luck there either. I have Windows 11 on this laptop and Bluetooth has stopped working there also (I thought it was different drivers on that.).

Pushing schedule of 26.04_stable tag in Amazon ECR Public Gallery

https://askubuntu.com/questions/1567290/pushing-schedule-of-26-04-stable-tag-in-amazon-ecr-public-gallery

This article states that the automatic upgrade to 26.04 LTS will be offered for 24.04 LTS users on August 4th. When is 26.04_stable tag available in Amazon ECR Public Gallery? Would it be the same as the release time of 26.04.1 LTS?

Icon display anywhere, but particularly on the clipboard is bad

https://askubuntu.com/questions/1567289/icon-display-anywhere-but-particularly-on-the-clipboard-is-bad

How did this become the standard display for clipboard?

It was infinitely better (in 24.10) when it just displayed everything as lines of text without double spacing, and without space highlighting, but displaying files as icons has never been good, not in file explorers and not in clipboard tools.

The icon should never be the primary visual for anyone who actually manages files. It has to be the single most tedious default that any and all operating systems default to.

How is this good?

For about a month now, my headless server (24.04 LTS) has been unable to connect to any repositories, including mirrors and any third-party repositories I use like Jellyfin or Docker. I know I have at least some kind of connection still because I can receive pings from all these repositories, but any sudo apt update always results in Network is unreachable and connection timed out for everything. I've also been having issues with trying to remotely connect to my Plex server, so it might be a more universal issue than just repositories.

Thinking this was some kind of settings issue, I tried a fresh install of the latest 26.04 LTS, but even it then was unable to connect to any Ubuntu mirrors during installation.

Is it possible for a router setting/issue to block updates like this, if it's not an issue with my specific install? It is connected directly to the router via Ethernet.

Create a Python apk using pycharm on kubuntu 24.04

https://askubuntu.com/questions/1567276/create-a-python-apk-using-pycharm-on-kubuntu-24-04

My apologies if this isn't possible. I'm just getting to grips with using python on Linux and trying to make an app for my android phone. I have a venv set up in pycharm with all the extensions I think I need. When I go to run buildozer through the terminal in I get this error:

$ sudo buildozer android debug
...
# Run '/usr/bin/python3 -m pip install -q --user appdirs colorama>=0.3.3 jinja2 sh>=2, <3.0; sys_platform!="win32" meson ninja build toml packaging setuptools wheel~=0.43.0' ...

#Cwd None
error: externally-managed-environment

× This environment is externally managed

I've tried running it directly in the konsole too from another venv that also has buildozer installed and I get the same error.

$source my-venv/bin/activate
cd file containing main.py
buildozer android debug

Could someone please explain to me what I need to do to fix this.

Edit: The complete konsole error

WiFi and ethernet suddenly drops for a brief time

https://askubuntu.com/questions/1567272/wifi-and-ethernet-suddenly-drops-for-a-brief-time

I have a laptop that has Ethernet plugged in and connected to the WiFi extender. And sometimes( quite rarely now, but more frequently before when i was on Zorin) both of these connections drop. I don't have any usb adapters, everything is in the laptop. What could be the potential cause? I've heard it might be because of power management.

On windows i don't have a problem like this, well i might have had, but it was only once a long time ago. Could this be problem related to drivers or maybe hardware?

I have Ubuntu 26.04

03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet Controller (rev 15)
    DeviceName: Onboard LAN Brodcom
    Subsystem: ASUSTeK Computer Inc. Device 208f
    Kernel driver in use: r8169

    Subsystem: AzureWave Device 4680
    Kernel driver in use: mt7921e
    Kernel modules: mt7921e

Is there any command i should execute?

PHP application doesn't recognize write permission

https://askubuntu.com/questions/1567258/php-application-doesnt-recognize-write-permission

I'm trying to install a php application (Nextcloud, if it's important) on my Ubuntu 24.04.4 server and I keep getting an error message saying:

                       Can't write into config directory!
 This can usually be fixed by giving the webserver write access to the config directory.

The thing is, the config directory already has 755 permissions and is owned by www-data. I've been trying to troubleshoot this with the Nextcloud forum and they just threw up their hands and said it's an Ubuntu problem. Their suggestion was to wipe the entire installation and rebuild; I can't do that because it's also my mail server and I need that.

Any help or advice gratefully accepted!

Oh, before I forget: the php installation is the latest 8.5 from Ondrej's repository.

(solved) WWAN refuses to connect - Ubuntu 26.04 (modem Fibocom L850-GL in laptop HP ZBook 15 G6)

https://askubuntu.com/questions/1567204/solved-wwan-refuses-to-connect-ubuntu-26-04-modem-fibocom-l850-gl-in-laptop

I have an internal modem (Fibocom L850-GL) in my laptop (HP ZBook 15 G6), and a SIM card. I checked he WANN in Windows (dual boot) and it's okay, but the WWAN refuses to connect in Ubuntu (26.04). It might be obvious, but I did not find the solution... Some help would be highly appreciated.

Here is my provider data for the APN:

name : Orange World
APN: orange
username: orange
password: orange
MCC : 208
MNC : 01
authentication: pap
Type of mobile virtual network operator : SPN
Value of the mobile virtual network operator : Orange F

I'm abroad, and the roaming is activated (at least, should be).

For my WWAN, I created a profile ("Orange Internet") including my provider data but MCC and MNC values are not included in this profile: I don't know if they are compulsory and did not find where to fill them in Ubuntu.

Bellow is the command line result and the logs:

Edit 1:
log updated.

Edit 2:
After a lot of tests and web search, I found a lot better configuration. Now, the modem connects, but Fiferfox still cannot reach pages. As my provider needs an authentication, I had to include in the bearer that an authentication is needed and then specify username and password and only allow pap connection. Very important: the APN mustn't be named in the bearer, otherwise, it doesn't connect.

st@ZBook-15-G6:~$ nmcli c add type gsm ifname wwan0at1 con-name Test4 gsm.apn orange gsm.username orange gsm.password orange gsm.initial-eps-bearer-username orange gsm.initial-eps-bearer-password orange gsm.initial-eps-bearer-noauth no gsm.initial-eps-bearer-refuse-eap yes gsm.initial-eps-bearer-refuse-chap yes gsm.initial-eps-bearer-refuse-mschap yes gsm.initial-eps-bearer-refuse-mschapv2 yes
Connexion « Test4 » (fdb43a3d-a956-4347-92ba-a350ddce6b33) ajoutée avec succès.

Then I activated data, roaming and switched on the mobile network in the GUI.

Now, the Modem connects, but internet is still not reachable (tested in Firefox). Remark: nmcli monitor says "limited connection"...

Here are the new logs:

Edit 3:
In console mode, I was able, for example, to ping 216.239.38.120 (google.com) but ping google.com did not work. So it was a DNS problem.

There was no DNS, so I manually included it:

nmcli c modify Test4 ipv4.dns "1.1.1.3 1.0.0.3"

nmcli c modify Test4 ipv4.ignore-auto-dns yes

and I did the same for ipv6 (after I tested it was already working only with ipv4):

nmcli c modify Test4 ipv6.dns "2606:4700:4700::1113 2606:4700:4700::1003"

nmcli c modify Test4 ipv6.ignore-auto-dns yes

After restarting the network, everything is okay.

====================================
useful tips (personnal reminder):

to modify a parameter (for example gsm.initial-eps-bearer-noauth): nmcli c modify Test5 gsm.initial-eps-bearer-noauth no
to list all profiles:nmcli con
to delete a profile (for example Test5): nmcli con delete Test5

SOLVED - Issue with kernel 7.0.0-15 after update from Ubuntu 25.10 to 26.04

https://askubuntu.com/questions/1566991/solved-issue-with-kernel-7-0-0-15-after-update-from-ubuntu-25-10-to-26-04

I have updated my Ubuntu from 25.10 version to 26.04, I received some error dusring the installation about the kernel.

At the first start I had a kernel panic error, I solved it starting my PC with the previous kernel version then I provided the following commands:

 sudo update-initramfs -u -k version

Now I can boot with any problem my PC with the latest kernel available 7.0.0-15.

But I think there is a problem, if I try to update my system via terminal this is what I have:

Same issue

----EDIT---- Thanks everyone for the advices. After reading around, I realized that dracut completely replaced initramfs and that their coexistence could cause problems. So I tried completely removing initramfs and checking if everything was OK with dragcut:

sudo apt purge initramfs-tools initramfs-tools-core initramfs-tools-bin
sudo apt install dracut dracut-core
sudo dracut -f --regenerate-all
sudo apt update && sudo apt upgrade
sudo apt autoremove

By running these commands the problem was solved and I no longer get the error message.

Configure two ethernet interface on Ubuntu

https://askubuntu.com/questions/1422727/configure-two-ethernet-interface-on-ubuntu

I'm trying to configure two Ethernet connections on the same computer running on Ubuntu but every attempts that I have made doesn't allow me to enable both Ethernet connections at the same time and I don't understand why. To have a better understanding of what I want to do, here is a description of the three involved computers represented at the following picture:

Computer A: my personal computer (running on windows) which is connected to internet
Computer B: a computer running on Ubuntu 22.04, connected via Ethernet to internet and to the computer C
C : a Ubuntu server 22.04 which is only connected to the computer B via Ethernet

I want to have access to the computer C from the computer A with SSH. I already have set static ips on computers B and C:

On computer B: xx.yy.zz.101 for the Ethernet port linked to the Ethernet port of the computer C
On computer B: xx.yy.zz.100 for the Ethernet port connected to internet
On computer C: xx.yy.zz.102 for the Ethernet port linked to the Ethernet port of the computer B

So, I should be able to access first from computer A to computer B with the command:

ssh xx.yy.zz.100

and then from computer B to C with the command:

ssh xx.yy.zz.102

Nevertheless, I can do only one of the two connections (depending on which one is active). The netplan configuration file of the computer B is:

---
network:
  version: 2
  ethernets:
    enp35s0: # Connection to computer C
      dhcp4: false
      addresses: [xx.yy.zz.101/24] # Need to configure a static ip
      gateway4: xx.yy.zz.1
    enp42s0: # Connection to internet
      dhcp4: false
      addresses: [xx.yy.zz.100/24] # Need to configure a static ip
      gateway4: xx.yy.zz.1
      nameservers:
      - addresses: [a.b.c.d, e.f.g.h]

and the command "ip a" shows:

Can you help me to understand why the two Ethernet interfaces can't be used at the same time? I already tried several options, like using the routes option with some priority but I have never succeeded to do what I want so I don't know which is simple way to do what I want.

Giving Plex Media Server Access to External EXFAT Drive on 19.10.1 RaspberryPi 4 4gb

https://askubuntu.com/questions/1208132/giving-plex-media-server-access-to-external-exfat-drive-on-19-10-1-raspberrypi-4

Edit2 (SUCCESS): First off, thank you to all who responded! I got my Plex server working perfectly. I didn't get email notifications with updates to the question for some reason so I just checked and got it all working.

@Terrance, I did manually create an actual mount point under "/media/HDD-M" (HDD-M s the drive name, HDD-Movies) through the initial guide I referenced. It did seem to work but Plex was still blind. Following that new mount point would lead me to my drive and allow access but made no difference to Plex. After following @user535733 response I realized the original guide I found may have allowed me to screw things up so I followed it backwards and undid everything before trying the link you posted @Terrance which worked after I messed with the mount point renaming a bit until Ubuntu was satisfied with my efforts. Just like that, it read and streamed without a hitch. For some reason, Ubuntu didn't like "/media/HDD-M" but once I changed it to "/media/SG" it worked without issue. No clue why that syntax made any sort of difference, but it did..

Either way, I really appreciate the assistance so much from you all. I was running Ubuntu fulltime ~13 years ago as a young nerdy kiddo and abandoned it when my mom got me a Macbook for graduating high school early so I forgot most of what I had learned. I plan on this getting me back into linux and eventually being proficient enough to help others like you all helped me.

Edit: I followed @user535733 instructions and immediately hit a wall at step 2 trying to edit permissions. I tried changing the file access to read and write and that seemed to work but had no effect on Plex. Upon trying to change the group I was modifying permissions for, a message came up stating I do not have permission to change the group.

I started off this incredibly frustrating journey a few weeks ago and came to this guide when plex couldn't see directories on my external: https://forums.plex.tv/t/using-ext-ntfs-or-other-format-drives-internal-or-external-on-linux/198544

This flew over my head very fast because of the way it was written, maybe I'm just an idiot and these steps really are perfectly formatted; but I couldn't ever get it to work at any point no matter how many times I tried.

Found AskUbuntu and looked through it which brought me to this post (plex folder access)

It was several years old which concerned me but I figured I would give it a shot. All the commands seemed to work fine but my drive is still inaccessible by Plex.

It is perfectly visible on my desktop, I understand this is a permissions issue with the way Linux is designed, not a fault of Plex or anything.

If anyone could help me out, I would really appreciate it because it's starting to drive me a bit crazy.

DHCP server won't start. Gives 'Not configured to listen on any interfaces!' even when configured

https://askubuntu.com/questions/536531/dhcp-server-wont-start-gives-not-configured-to-listen-on-any-interfaces-eve

I have just setup isc-dhcp on my server. I even setup the correct interface. But still the dhcp server won't boot. Its says Not configured to listen on any interfaces! in the syslog. And when I try dhcpd -t /etc/dhcp/dhcpd.conf it gives this error : /etc/dhcp/dhcpd.conf: interface name too long (is 20

Here's my dhcpd.conf :

Is there a tool for removing metadata?

https://askubuntu.com/questions/308250/is-there-a-tool-for-removing-metadata

the title says it all. is there a tool?

I installed ExifTool, but can't find a way to remove all at once with one command.
