I've been able to use in terminal:

sudo kill 4893 (to stop fwupd, using its PID, from running w/o any issues

Today I tried recklessly in terminal: sudo killall fwupd

now my 'files' is querky, crashng, etc. entire display will freeze, blink off, then back on and seem normal until trying something else then blink on/off...

so tried in terminal:

sudo systemctl enable fwupd

which ran for awhile then had to just do ^c to stop and then typed exit to close terminal

Tried GRUB recovery but didn't help...

everything else works fine - just file system access is screwy

any advice?

I've been trying to figure out for days what this problem is. It happened after I updated to Kubuntu 25.10. At first it minced the bootloader somehow, but I fixed that. Now I have another problem.

Safe Boot is off, EFI firmware exists, and the grub menu is correct, but when I try to boot into Kubuntu, I get nothing but a black screen. Booting from recovery mode works, though. I don't dual boot, there is no Windows install.

I've tried reinstalling Kubuntu numerous times to no avail.

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub-efi of
nvme0n1p2,
using the following options:  nvme0n1p1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file restore-efi-backups

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your UEFI firmware boot on the The OS now in use - Ubuntu 25.10 entry (nvme0n1p1/efi/****/grub****.efi (**** will be updated in the final message) file) !

I'm new to fiddling with Kubuntu, so I might be missing something obvious. I've tried to find info online, but nothing seems to work.

What could be causing this problem?

Last week I had a strange error pop up on my Ubuntu, which ended up causing my LUKS key header to become corrupted. While trying to troubleshoot and get back into my operating system I noticed the grub menu was reading this - GNU GRUB version 2.14~git20250718.0e36779 - instead of what I'm used to seeing which would have just been GNU GRUB version 2.14.

It appears that my GRUB/bootloader was the culprit.

I used an old backup from a live USB to install a fresh operating system as I made the mistake of not saving a key header backup. Upon installing the fresh OS, the GRUB boot menu looked normal - GNU GRUB version 2.12 -

After connecting to the internet and updating normally a couple of times, my bootloader appears to have reverted back to the strange GRUB version with what looks like a specific Git identifier attached to it. I haven't run into any issues yet, but can anyone explain what this is? I've tried installing a fresh grub file, but this is still showing up

IMO it looks like a non-normal version of the GRUB menu is being downloaded onto my system through the official repositories

When I try to run sudo service cups start in Kubuntu 24.04 I get a Service not found error.

Is there a way I can check compatibility of my HP laptop for Ubuntu OS I am tired of windows with the spying and selling my data and would like to move away from Windows 11 pro.

For some unknow reason it just disconnected. Now can't get it to reconnect.

I keep going round and round on suggested fixes. Nothing seems to work ... any ideas? Need more info??? Thanks for any help!

Since I'm having audio issues on both my Ubuntu machines, felt like using my improved techniques to figure out more about what's wrong on the one that at least sometimes works.

So, HDMI via internal graphics that sometimes appears as an Output Device in Sound settings, but sometimes doesn't, and for all times eventually is fixed as long as I keep resetting until a success.

But I'll rather stop having to repeated reset after a required post-update reset.

So, what I know:

~$ lspci | grep -i audio
06:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Raven/Raven2/Fenghuang HDMI/DP Audio Controller

But that doesn't currently appear in alsamixer but it did when I checked during a time it did work.

And aplay -l is empty:

**** List of PLAYBACK Hardware Devices ****

ls /proc/asound gives:

card1 cards devices hwdep modules oss pcm seq timers version WEBCAM

sudo dmesg mentions errors creating the cards:

snd_hda_intel 0000:06:00.1: cannot find the slot for index 1 (range 0-1), error: -16
snd_hda_intel 0000:06:00.1: Error creating card!

I'm assuming I'm not getting any audio out of my HDMI monitor because the card as alsamixer reports it, has 00 for everything and that everything is S-PDIF?

Someone else solved their S-PDIF issue, a.k.a "No audio from NVIDIA GPU, alsamixer only showing S/PDIF for HD" by:

After disabling intel gpu and replacing noveau with Nvidia prop drivers. I verified that the Nvidia driver loaded with dmesg and finally I had audio

Unfortunately, I can't do that since I have a NVIDIA GT 220 and that's stuck using nouveau.

Also found this 6-year-old bug that was fixed by a regression, and that's for archlinux anyway?

It might also be relevant that sometimes I lose the HDMI from my mixer if I wake up my monitor from sleep. And sound-test doesn't produce sound.

Currently installed sound-y packages are:

alsa-base
alsa-toplogy
alsa-ucm
alsa-utils

pipewire-alsa
pipewire-bin
pipewire-pulse
pipewire-bin

wireplumber

linux-base_4.5ubuntu9+24.04.1

Nothing that starts with pulse

And my monitor is a Hanns-G HG216D.

From earlier questions / answers I am told I cannot upgrade my laptop to the newer Ubuntu if that is the case how do I wipe the hard drive so as to reinstate Windows?

Previous post stated I cannot use laptop on newr Ubuntu 24 so would like return to Windows operating system which requires Ubuntu to be wiped from hard drive?

I'm running Ubuntu 24.04 server on a raspberry pi 4b. I set it up to auto login. It displays "Ubuntu login: gene (automatic login)". I'd prefer that it didn't display anything.

As per the login man page, in the /etc/login.defs file I tried both: HUSHLOGIN_FILE /etc/hushlogins HUSHLOGIN_FILE .hushlogin creating the files /etc/hushlogins and ~/.hushlogin respectively.

Neither of these inhibits "Ubuntu login: gene (automatic login)" from being displayed.

Should this work? Any other ideas how I could stop this from being displayed?

Thanks

Same issue as StackOverflow #79881893 on Ubuntu — InsightFace OpenVINO falls back to CPU on Intel UHD 620

I’m experiencing the exact same issue Describe here

I am using the same device and hardware as in that post (Intel iGPU — UHD 620), and I’m running Ubuntu.

InsightFace detects the OpenVINO provider, but it ignores GPU options and always falls back to CPU, even though GPU works when tested directly with ONNX Runtime.

I'm having a situation where applications are very slow to start on first launch, and often freeze with the standard "Application is not responding" dialog in GNOME popping up. If I give it a few seconds (sometimes up to a few minutes!), it will go away and the application will act like nothing's wrong. However when I switch to a different application, the same thing will sometimes happen. This happens often enough to be very annoying. I thought it might have something to do with the video drivers, since this is a bleeding edge new machine (Intel Arc graphics, and dual screens in the laptop). But reinstalling the graphics drivers doesn't fix the issue. I've also tried upgrading and downgrading to different versions of Ubuntu (24.04, and 25.10), and still have same issues, so I know it's not specific to 25.04, which is what I'm currently using, and it's likely specific to this machine (ASUS Zenbook Duo with Intel Arc Graphics).

It's odd because I know the graphics card is working - I've been using it to render Blender stuff for various clients. There are the occasional freezes, but nothing is actually broken. The mouse cursor moves freely, and the rest of the system seems to run smoothly while the application is unresponsive. I've been getting by by switching tasks, while the applications recover, which works, but is definitely not ideal.

My laptop is an ASUS Zenbook Duo, UX8406C, and here's my full system details:

Currently, after removing pipewire-pulse and replacing it with pipewire-alsa because apparently alsa is the current thing now, and PulseAudio is depreciated...

Now my alsamixer is a little bit weird. There's now 3 soundcards, not two, and the first one is unnumbered but also the "(default)" while my other two are still there.

I tried the first and second highest scoring answers of How do I select a default sound card with alsa?, so now I have:

/etc/asound.conf which is:

defaults.pcm.card 0
defaults.ctl.card 0

Since the 0-index card is the one I want.

And my /etc/modprobe.d/alsa-base.conf now ends with:

options snd-hda-intel index=0 vid=0x#### pid=0x####

Where #### are the numbers I get from the end of alsactl init since those numbers fit the 0x#### format more and the recommended numbers from the end of lspci -nn | grep Audio for my soundcard weren't working.

I rebooted my computer after every change to alsa-base.conf, so unless that doesn't make it reboot, that's not the issue.

I have a laptop running Ubuntu 25.10. I'd like to make the following setup with three screens: The build-in laptop screen, a projector, connected via HDMI, and a portable USB-C monitor. I want to mirror the view on the laptop screen to the projector, and have an independent view on the USB-C monitor. The system settings as such don't allow me to do this. It's either three entirely separate views or the same view across all three screens. I have looked at this question, which is exactly what I want, but the solution there doesn't work for me.

I have tried the following gdctl command, without success:

$ gdctl set --logical-monitor --primary --monitor DP-3 --logical-monitor --monitor eDP-1 --monitor HDMI-1 --right-of DP-3
Failed to create configuration: Different monitor resolutions within the same logical monitor

Both eDP-1 (built-in laptop screen) and HDMI-1 (projector) are set to 1920x1080 at 60 Hz, so the error message doesn't make sense to me. Here's the output from gdctl show which hopefully helps to shed some light on this issue:

Can anyone suggest why gdctl set doesn't work?

Feeling pretty stupid right now.

I went through the upgrade procedure to go from 22.04 to 24.04. I haven't lost any data and my machine is functional (thank goodness, since it's what I use for the day job).

But while enabling and upgrading third-party software I noted that sources.list was still using "jammy" instead of "noble".

Long story short, I got into the situation where I cannot upgrade anything because this happens.

I was trying to follow various "fixes" from various articles but it's just got worse.

Any help in digging myself out of this mess would be appreciated.

EDIT 1: --- /etc/apt/sources.list (comments removed)

After the upgrade these were all still pointing at "jammy", I tried just changing them all and ran into errors, so (after other changes) started to edit them one by one, and this is as far as I got.

(I had tried upgrading virtualbox but I think that's where it started running into issues.)

EDIT 3: --- Various install/remove Virtualbox, and upgrade without it

First I simply tried to install virtualbox (Jammy), it said it would be deleting virtualbox-7

Then I remembered one of the references I found said that - to get rid of virtualbox - I should manually delete the relevant files from dpkg. Which I did (yes, I wish I hadn't).

When attempting to remove virtualbox-7 these messages popped up:

dpkg: warning: files list file for package 'virtualbox-guest-dkms' missing; assuming package has no files 
currently installed
dpkg: warning: files list file for package 'virtinst' missing; assuming package has no files currently ins
talled

 currently installed
dpkg: warning: files list file for package 'virt-manager' missing; assuming package has no files currently
 installed
dpkg: warning: files list file for package 'virt-viewer' missing; assuming package has no files currently 
installed

It then proceeded to load virtualbox-6.1.50 DKMS files... there followed sanity check errors:

which I assume exist because it didn't delete virtualbox-7 and finally:

It's not looking good, is it?

To give a quick explanation: A friend helped me rent a contabo server to which I connect using MobaXterm RDP and that session is running via Ubuntu LTS OS (Hopefully it makes sense, since I am not super tech savvy).

I don't run anything else other than a modded minecraft server. Problem is every day at around 10pm CET I get disconnected from the RDP session and after return the terminal is gone and if I use a screen and then detach it, it turns up dead afterwards.

Updates:

• After using uptimeI can see that the server itself does not go offline.
• I contacted Contabo support, they migrated the server (didn't fix)
• Was told to view system logs, which I did, sadly can't contact support at this time to pass them along. I assume it would not be safe to share them here.
• Tried using tmux and screen. After reconnecting tmux showed that there was nothing running as for screen it still listed my named screen, but I could not reattach and as its status it had "????" (on RDP)
• Will be trying to just use SSH and screen there this time (fingers crossed)
• When looking for ways to stop the RDP connection from shutting down I keep running into editing group policies and session limits, but try as I may I can't seem to find a definitive answer/step-by-step process on how to do this for my exact situation.

Would love any information about how I could fix this issue or be directed to a place more appropriate for this question. Be it troubleshooting or direct fixes any extra information gained on what causes this and potential fixes would be awesome. Thank you for your time.

I just upgraded from Ubuntu 20.04 to Ubuntu 22.04. All scrolling was working fine on the v20.04 but now completely fails with all applications after I upgraded to v22.04. The OS was the only thing I updated. I found this and tried but it failed.

I'm on Ubuntu 18.04 I believe. I've recently started a new Minecraft server, and it works just fine locally and from another desktop (connected with the ip4), however when I try to connect with the public IP address + port (example) 165.242.53.1:25565 it doesn't show.

I'm sure that I port forwarded well (I already ran a Minecraft server several times on Windows), but I just can't figure out why it doesn't work.

I recently discovered that netplan can manage hostapd accesspoints, but this is the extent of the example config:

    wlp1s0:
      access-points:
        "guest":
           mode: ap
           # no WPA config implies default of open

I can find no other documentations of how to define other settings like WPA security and passphrase. I need the following hostapd.conf settings defined and EAP in the future as well:

interface=wlo1
bridge=br0
hw_mode=g
channel=0
ieee80211d=1
country_code=AE
ieee80211n=1
wmm_enabled=1

ssid=SSID
auth_algs=1
wpa=2
wpa_key_mgmt=WPA-PSK 
rsn_pairwise=CCMP
wpa_passphrase=*********

I am aware netplan requires NetworkManager for access point configuration, and I don't know if keeping the bridge managed by networkd will hinder the bridging. If possible, please clarify this point as well.

I'm trying to set up a couple of NFS mounts to automatically mount at boot. I'm not new to this; I did this on Solaris in 1985.

Here's what I have in /etc/fstab:

iomega:/nfs/Music   /music  nfs rw,auto,user    0   0

It doesn't mount at boot and leaves this message in syslog:

Mount process exited, code=exited status=32

It didn't work in 18.04, and I just upgraded today to 18.10 and it still doesn't work. If I do a mount -a after boot, that fs mounts normally. I've tried several suggestions about adding systemd-specific parameters to the mount options, but none of them worked.

This is basic functionality. It should JFW. Can anybody tell me what the exit code 32 means and how to make this work?

I have a dual Win10 boot and (K)ubuntu 18.04 on a Fujitsu Ultrabook UH572 i5/8GBram and (K)ubuntu is running on a 32GBSSD. After a clean install of (K)ubuntu 18.04 I noticed that the touchpad wasn't working...On Win everything works fine.

It's the first time I'm running Ubuntu on this machine so I don"t know what the issue could be. In the past I never had an issue with the touchpad. Maybe it has to do with the fact that its a click-touch-pad? It has no buttons just a big area, kind like a Mac.....

In any case I can see the touchpad when typing xinput list in terminal. Below the output:

kongking@UH572:~$ xinput list

I've tried editing the etc/default/grub file and replacing "quiet splash" with "acpi=force", according the link below: SynPS/2 Synaptic Touchpad not working in Ubuntu 17.10, with no luck.

Any ideas how to tackle this??

Sorry if I misuse the Forum and your time, with an Kubuntu question but whenever I have a problem I search at Ubuntu solutions....and to be honest I couldn't find a more relevant site.

Many thanks, μρ .

I want to install a driver for the TP-Link Archer T2UH AC600 (Version 1) USB WLAN adapter on a newly installed Ubuntu 16.04 LTS (Linux kernel 4.4.0).

During compilation I got the error:

/home/peter/src/mt7610u_wifi_sta_v3002_dpo_20130916/include/cfg80211.h:35:49: error: ‘IEEE80211_NUM_BANDS’ undeclared here (not in a function) struct ieee80211_supported_band Cfg80211_bands[IEEE80211_NUM_BANDS];

so I tried the solutions given in TP-Link T2U (AC600) usb WLAN adapter driver on Ubuntu 16.10 with the following result:

$ sudo insmod mt7610u.ko

insmod: ERROR: could not insert module mt7610u.ko: Unknown symbol in module

I can not figure out in the other posts what to do next. Anybody?

O! Reading topic TPLink AC600 Driver Install Fails in Ubuntu 16.04 with Unknown Symbol I found out that this is a IMPOSSIBLE mission? No TP-Link AC600 works with a kernel 4.4 or higher???

I need to upgrade the php version to 7.2 in my Lampp. Actually, when I am checking php -v in terminal, it's showing the following result:

PHP 7.2.1-1+ubuntu14.04.1+deb.sury.org+1 (cli) (built: Jan 11 2018 22:52:58) ( NTS )

But I am running the file from opt/lampp/htdocs and there I am getting the php version as 5.6.3 which needs to be upgraded to 7.2. I was referring the following steps to install this originally.

Recently after a sudden power failure my 1TB hard drive (/dev/sda1) failed and will not mount.

It says:

Error mounting /dev/sda1 at /media/zangar_/4b84d62b-520d-408e-addc-7a2bf52cc4e3:   
Command-line 'mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/sda1" "/media/zangar_/4b84d62b-520d-408e-addc-7a2bf52cc4e3"'   
exited with non-zero exit status 32:   
mount: wrong fs type, bad option, bad superblock on /dev/sda1,    
missing codepage or helper program, or other error  

In some cases useful info is found in syslog - try
dmesg | tail or so.

I tried e2fsck but it asks me to Get a newer version of e2fsck! Then, I looked at all the other posts about updating e2fsck (here and here.) These answers did not work for me.

Transcription of the error:

e2fsck 1.42.13
/dev/sda1 has unsupported feature(s): metadata_csum
e3fsck: Get a newer version of e2fsck!

Any help is greatly appreciated, as I have time sensitive documents in the unmountable drive.

I have googled and searched and i want to move back to windows (as this setup works FLAWLESSLY with windows 10, sigh)

I have an MSI A68HI-AC mb with A10-something CPU, 12GB ram, a shiney gigabte RX 460 2gb gfx card and much much pain.

1 week trying to get hardware graphics on this on Linux, I've re-installed more than 10 times with Kubuntu, mint and ubuntu.

Currently i have ubuntu 14.04.1 and updated the kernel to 4.9. This is the MOST i have advanced and its still working, the other distros all crashed X / Xorg / grafics anything at this point. And yes, i even tried 17.3, 14.4 and flicking up and down kernels with each distro. I'm serious when I said I have tried a LOT of alternate "fixes".

kernel 4.9 It apparently has improved support for ATI/AMD GPUs. apparently. i cant copy and paste stuff from the Linux box as I am writing this from my working windows 8.1 laptop.

$ lspci | grep VGA
VGA compatible controller Kaveri R7                ## assuming its my on-cpu graphics
VGA compatible controller Device 67ef (rev cf)     ## assuming my RX 460?

$ glxinfo | grep OpenGL
renderer string: Gallium 0.4               ## I assume again this is onboard/CPU and not GPU)
core profile string: 3.3 Mesa 17.1.0-devel1 - padoka PPA
version string: 3.0 mesa
ES profile string: OpenGL ES 3.0

I am about to install the AMDGPU-Pro ...annnnnnd it gone. I need to log in to the pc using Ctrl-Alt-F4

I am using Hyper-V for my Linux lab.

I have Ubuntu Server 16.04 which contain 2 network cards, shown in the system as 2 interfaces.

eth0: Configured to get IP address from DHCP server (my D-Link router provides internet access).

eth1: Configured as static IP for my internal network.

This is the /etc/network/interfaces file that I edit:

# Primary Network interface
Auto eth0
Iface eth0 inet DHCP

# Internal Network interface
Auto eth1
Iface eth1 inet static 
address 192.168.1.1 
netmask 255.255.255.0 
gateway 192.168.1.254 
dns-nameservers 192.168.1.254

After I finish to edit the configuration file and reboot, I lose my Internet access.

Even if I try to ping to 8.8.8.8 from eth0 (with ping -I eth0 8.8.8.8), it fails.

When I delete the internal network interface from the configuration file and reboot, my internet connection gets restored.

What am I doing wrong? How can I configure my machine so that the eth0 device will use for internet access only, and the eth1 will use for my internal network?

I guess you could say that I'm a slightly educated noob (I know, a little knowledge is a dangerous thing).

My drive worked fine in Mint 17.3, but I am now running Lubuntu 16.04 and my DVD drive has not worked yet. I have tried multiple CDs and DVDs; music, data, and blanks.

lsblk -f returns:

sr0          

cat /dev/sr0 returns:

cat: /dev/sr0: No medium found

So I tried lshw and got this:

*-scsi

     logical name: scsi0
     capabilities: emulated
    *-cdrom
         description: DVD-RAM writer

         serial: [
         capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
         configuration: ansiversion=5 status=nodisc

And then there's this:

$ mkdir ~/dvd | sudo mount /dev/sr0 ~/dvd
mount: no medium found on /dev/sr0

I'm pretty much grasping at straws at this point. So, what now?

Update on info: I can locate it in Disks with no problem, but it shows no media when I have a DVD in the drive. I have already cleaned the lens, but that was never an issue as it worked fine before I installed Lubuntu 16.04

I need some help, I installed Ubuntu 14.04 from 12.04. I had some problems when it rebooted so I had to install unity using sudo apt-get install ubuntu-desktop and continue tu update all packages using the virtual console. Ctr + Alt + F1.

But when I tried to login, after entering my user and password nothing loads, no dash, no launcher, etc. I tried everything but most I find is for older versions so I need help with this version or how to install a Gnome panel to replace unity and set it as defaul.

using ccsm show the unity plugin checked.

P.D.: I'm using an Acer Aspire 4520 with and Nvidia card.

I have a problem with a installation of ubuntu 12.04 server on HP SL4540 with raid controller b120i. Ubuntu during installation does not recognize the raid controller, and displays the disk separately. Can you tell me how to recognize the controller?
