How to logically isolate/disconnect second NVMe drive from Ubuntu system for a dual boot system? https://askubuntu.com/questions/1560606/how-to-logically-isolate-disconnect-second-nvme-drive-from-ubuntu-system-for-a-d

I am fairly new to Linux and still learning. I am using two different OS installed on two separate NVMe drives as a dual boot system. One of them is Ubuntu 24.04.3 LTS and I want to isolate/disconnect other NVMe drive (which is used by other OS system) from Ubuntu OS to prevent accidental formatting or potential altercation/formatting by penetration or ransomware/malware attacks. Please note that I do not wish to use system's BIOS/UEFI settings to isolate the second NVMe drive and physical isolation. Is there any way to perform this task in Ubuntu?

Ubuntu won't turn on the Wi-Fi [closed] https://askubuntu.com/questions/1560605/ubuntu-wont-turn-on-the-wi-fi

I have Kubuntu 18.04 installed on an old laptop, and what's happening is that the Wi-Fi won't turn on. I don't know if it happened after a power outage because I don't have a battery, and when the power goes out the laptop shuts down and I have to turn it on again, or if it was after an update. When I start it, it shows the following message:

[ 71.586695] iwl3945 000:06:00.0 iwlwifi-3945-2.ucode firmware file req failed: -2 [ 71.595171] iwl3945 000:06:00.0 iwlwifi-3945-1.ucode firmware file req failed: -2 [ 71.595173] iwl3945 000:06:00.0 Could not read microcode: -2

So I don't know if it's that the Wi-Fi driver has gone missing.

How do i dualboot ubuntu without boot menu or usb? [duplicate] https://askubuntu.com/questions/1560604/how-do-i-dualboot-ubuntu-without-boot-menu-or-usb

Look, i want to experience the ubuntu outside of virtual machine and i want to install ubuntu on my laptop. There are two problems though. First, i don't have a spare usb or something like that. Second, i have a big fear of bios-related menus meaning i don't want to access novo menu, bios setup or boot menu. My lenovo laptop didn't came with intel rst or bitlocker meaning im prepared for install. Any comment saying "bro go buy a usb/enter boot menu" will be ignored as they bring no beneficial value to my problem.

P.S.: i have the installation partition prepared on my secondary 1tb drive and ubuntu version is 24.04 LTS.

How can I fix the broadcom drivers on this Dell XPS 1394 running 24.04.3 LTS? https://askubuntu.com/questions/1560602/how-can-i-fix-the-broadcom-drivers-on-this-dell-xps-1394-running-24-04-3-lts

Previously the wireless card was detected and worked on Ubuntu 18, 20, and 22 LTS. 1-2 months ago they quit - likely after an improper shutdown, but it wasn't critical enough to fix at the time. I just upgraded to 24.04.3 LTS in hopes that would fix it, but it didn't.

Things I've checked:

  • bios has the card enabled
  • lshw shows the card
  • Check for firmware updates, install b43 firmware, update with the bug (answered this question in the process)
  • "Airplane mode" is off

Do I need to uninstall/purge and reinstall the b43 drivers?

Want multi-page from flatbed option on my HP printer https://askubuntu.com/questions/1560600/want-multi-page-from-flatbed-option-on-my-hp-printer

I have HP Linux Imaging and Printing Systemm 3.23.12, and it finds my printer, printing to and scanning from it.

On another post in this forum, I have seen a dialog box that supposedly comes from 'simple-scan' that includes scanner options for scanning from the document feeder and scanning multiple pages on the flatbed (i.e., you scan one page, then subsequent pages you scan become additional pages of the same PDF instead of a different PDF for each page.

How would I go about getting that version of the HPLIP scanning software?

Game development in Ubuntu? https://askubuntu.com/questions/1560595/game-development-in-ubuntu

My kid would like to start writing videogames, his pens use Roblox Studio, and I wonder which alternative I could propose him on Linux (Ubuntu 24.04 to be more specific)

Time in Kubuntu is not what it's supposed to be https://askubuntu.com/questions/1560594/time-in-kubuntu-is-not-what-its-supposed-to-be

I'm really not sure what the heck is going on here... I had recently switched to Kubuntu from Linux Mint (XFCE), and all things considered, I love it. The Plasma desktop is nice and responsive, and I plan to stick with it from now on. There is one issue that seems to be kinda... odd. For some odd reason, the entire system seems to think that the time is 1 am (at the time of writing this) where I live (PST, btw), however, it's supposed to be around 8-ish (again, at the time of writing) Some apps, like Discord, for example, display the right time when I have it set to my local time zone, while others just assume that the time Kubuntu thinks it is is right.

This is what timedatectl outputs

local time: Sun 2025-12-07 01:44:36 PST #this here is not supposed to say that
               Universal time: Sun 2025-12-07 09:44:36 UTC
                     RTC time: Sun 2025-12-07 09:44:36
                    Time zone: America/Vancouver (PST, -0800)
    System clock synchronized: no
                  NTP service: active
              RTC in local TZ: no

I hope that this is at least fixable... I kinda need my clock to be right

Dual booting with another Linux OS already using systemd-boot to install Ubuntu Studio https://askubuntu.com/questions/1560590/dual-booting-with-another-linux-os-already-using-systemd-boot-to-install-ubuntu

Can an Ubuntu Studio installation process recognize an existing systemd-boot system for dual booting purposes? I don't want Grub. I use EndeavourOS as my main OS, but wish to install Ubuntu Studio on a separate disk. BTW: I do not use Windows.

I am a very long-term Linux user. I have read this helpful Ubuntu page, but it does not actually say what the install would do or whether it offers any options. I have tried the install process as far as I dare, but there was no telling what it would do about installing a bootloader. This does not help as I do not want to share a \home folder.

Loudness equalisation in Ubuntu 24.04 https://askubuntu.com/questions/1560577/loudness-equalisation-in-ubuntu-24-04

I'm currently using Ubuntu 24.04. Is there a way to get loudness equalisation similar to the feature that's built into Windows where it more or less equalises audio sources on your PC? I'm finding it a little annoying that the audio can go from being very quiet to very loud so I'm constantly having to adjust the volume depending on what I'm listening to, watching or playing.

My latest Ubuntu started to lag the mouse and keyboard since yesterday. but not at all times https://askubuntu.com/questions/1560566/my-latest-ubuntu-started-to-lag-the-mouse-and-keyboard-since-yesterday-but-not

I use Ubuntu 24.04 in Gnome. I haven't made any changes in the last few days except for a software update, however I am having a problem with my wireless mouse and keyboard which have started to lag. Should I try another USB slot for my wireless mouse and keyboard set?

Preparing Strava images for AI analysis https://askubuntu.com/questions/1560550/preparing-strava-images-for-ai-analysis

I routinely prepare screenshot graphs from my running activities from Strava for input and analysis by an AI on the free plan of ChatGPT. There are substantial limitations for image upload and analysis with ChatGPT's free plan, currently it allows only 3 images for detailed analysis per 24 hour period and these images have a size limitation.

Currently I stitch the 3 required images together with GIMP, convert them to a single image, resize this image and then export the final image. Cumbersome...

How can I semi-automate this process using the Ubuntu command line, producing a small but clear image that can be easily analyzed by an AI? An example of 3 typical images / graphs is here, labelled on my system splits.png, power.png and HR.png:

enter image description hereenter image description hereenter image description here

I usually organize the taller image 'Power' to the left side and the remaining images stacked on top of each other on the right side...

Copy big data best practice [closed] https://askubuntu.com/questions/1560503/copy-big-data-best-practice

I want to copy appr. 12TB of data from one storage to another on a ubuntu machine (ssh terminal, no desktop).

When I would start this with rsync the terminal/ssh session would loose connection after some time and I am not longer able to check the status.

So what is here the best practice to copy big data? Rsync output in file, tmux or some other way, how the pros do this? I am not interestet in getting live information for each file but I want to have information if there is/was an error and maybe an overall/atm status (atm XX percent, running time, avg speed, like that).

Bluetooth can not be turned on after login with new laptop and fresh installed 24.04. upgrade to the latest 25.xx. issue still presents https://askubuntu.com/questions/1560212/bluetooth-can-not-be-turned-on-after-login-with-new-laptop-and-fresh-installed-2

behaviour is following:

  • on the login screen. the Bluetooth is toggled on, BT device are visible. seems working
  • after login (entering PW and get into Ubuntu), the Bluetooth button is gray, and can not be turn on.

only solution for me now, is each time to "rmmod btusb btintel && modprobe btusb btintel". but once the laptop is log out and back, the BT icon can not be turned on again.

How to turn OFF (and ON) a single monitor in a multiple-monitor-system on Kubuntu 24.10 (with Wayland)? https://askubuntu.com/questions/1530446/how-to-turn-off-and-on-a-single-monitor-in-a-multiple-monitor-system-on-kubunt

This could be achieved with X easily, but although looking extensively on AskUbuntu and other sites, I did not find a solution for Wayland :-(

The closest I came to was the command kscreen-doctor --dpms off. Unfortunately this turns off all monitors at once. But I'm looking for a more granular command that can turn on/off a single monitor alone.

Some posts suggest that this depends on the compositor. So I checked which compositor Kubuntu 24.10 uses with inxi -Gxx | grep compositor and the output is:

compositor: kwin_wayland driver: X: loaded: modesetting unloaded: fbdev,vesa

But what command or command-line-tool can I use to achieve the given task?

How to install wxWidgets on Ubuntu 24.04 [duplicate] https://askubuntu.com/questions/1522811/how-to-install-wxwidgets-on-ubuntu-24-04

I need wxWidgets as I'm getting the error. But I couldn't make sure what repository do I need for wxWidgets and I don't know how to install it.

checking for wx-config... no

Recommendation for note app https://askubuntu.com/questions/1495192/recommendation-for-note-app

I'm looking for recommendations for a note app. I'd like it to be cross platform (Android 13 and Ubuntu 22.04), to be able to set reminders, and I'd really like for it to be able to import notes from ColorNote on Android. I have over 4,500 of them, it would be a lot to input manually.

I've been looking at a few lists, such as https://itsfoss.com/note-taking-apps-linux/

My current solution is emulation. Or at least I'm trying to figure out emulation, but I'm having issues with Waydroid and I don't know how to solve them yet.

Edit: Joplin seems perfect, thank you very much!

Network UPS Tools (NUT) - Ubuntu 20.04 - Init SSL without certificate database Error: Data stale https://askubuntu.com/questions/1401545/network-ups-tools-nut-ubuntu-20-04-init-ssl-without-certificate-database-e

OS: Ubuntu 20.04 NUT: 2.7.4-11ubuntu4 amd64

I have installed and configured the associated .conf files for a "Standalone" mode Network UPS Tools (NUT) driver/server/client using USB connector to UPS. The behavior I am experiencing is as follows:

1.) Initially when the applications are run (after a reboot), the upsmon (client) seems to be able to connect to the upsd (server) and access status information from the UPS. Example as follows:

upsc "my ups name"@localhost
 
Init SSL without certificate database

battery.charge: 100
battery.charge.warning: 30
battery.runtime: 2450
battery.type: PbAc
battery.voltage: 0.0
battery.voltage.nominal: 12.0
device.mfr: Tripp Lite
.....

2.) After some time period elapses, and I run the same command, the following occurs:

upsc "my ups name"@localhost
Init SSL without certificate database
Error: Data stale

My high level question is how do I fix this "Data stale" problem? My lower level question is can I run this without SSL certificates (this is a Standalone implementation, so I am not concerned about "man-in-the-middle" issues with user/password in plain text going over the network).

I have already read the thread nut (UPS) and SSL certificates on this forum, but it is not directly related to the problem above.

Many thanks in advance for the forums help (I am a Noob).

I think I have established that the issue lies in the USBHID-UPS driver and this SSL certificate message is a "red herring" in terms of my issue. The answer to my question lies somewhere in the driver interface as when I restart the driver (usbhid-ups) the issue resolves itself for an undetermined period of time and then fails again.

Further to this, if I stop/start the driver this "resets" the connection and then upsc command works until some time later when it shows Init SSL without certificate database Error: Data stale.

Commands to stop/start driver:

sudo /sbin/upsdrvctl stop
sudo /sbin/upsdrvctl start
Lenovo Battery Conservation mode fail https://askubuntu.com/questions/1367327/lenovo-battery-conservation-mode-fail

I've been trying to get battery conservation mode to work by doing the below, but ultimately I have been unable to get the setting to change from 0 to 1

Running kernel 5.11.0-37

Tried previous posted solutions of

echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode

however, when I look at the file ...

cat /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode
0

Trying this using sudo su also had no effect.

Also tried editing the file manually as root, but when reopening the file it is once again set to 0

Tried: TLP, which seems to confirm I can set an upper threshold for my Lenovo 7i, but it also references conservation_mode being set as 0 (100%)

sudo tlp setcharge 80 1

18.04 Error while booting. Hangs on line "stopping user manager for uid 123" https://askubuntu.com/questions/1057642/18-04-error-while-booting-hangs-on-line-stopping-user-manager-for-uid-123

My sisters main computer is having major problems booting up and I cant quite figure it out. During boot it hangs on line "stopping user manager for uid 123".

I have done both sudo dpkg-configure lightdm as well as editing the custom.conf file by using command sudo nano /etc/gdm3/custom.conf and then unmarking the 'WaylandEnable=false' line.

Still nothing. I removed her nvidia graphics card and ran the sudo dpkg-configure lightdm line again. This seems to fix the problem for most people. Booting up shows me a blank screen. After pressing CTRL+ALT+F4 I begin to type her login and then the regular Ubuntu login appears out of no where. At least she can use her computer right now but its a pain to get it to the regular logon screen. Ive ran all updates and everything is updated and seems great otherwise.

Any tips or commands I could do to solve these issues? Ultimately Id like to get her computer working again with the nvidia card in it since she plays games like WoW (worldofwarcraft).

Thanks so much!

Malayalam Subtitle font rendering issue with VLC for 16.04 https://askubuntu.com/questions/951181/malayalam-subtitle-font-rendering-issue-with-vlc-for-16-04

When I use a Malayalam (a very popular south Indian language) srt file with VLC (UTF-8 + Malayalam font in preferences) for Ubuntu 16.04, the subtitles are displayed. But not correctly. Certain joint symbols break giving an awful, unenjoyable subtitle display. Please check the screen shots:

enter image description here

enter image description here

For comparison, this is how that line should actually look with the AnjaliOldLipi font:

enter image description here

How can I fix this issue? It works fine with SM Player. I also took some suggestion for using .ass instead of .srt. It didn't go well either.

I could only think of some issue with font rendering inside VLC. Malayalam works well in most other software. Thanks.

Apply static IP address change in /etc/network/interfaces in Ubuntu 16.04 https://askubuntu.com/questions/793877/apply-static-ip-address-change-in-etc-network-interfaces-in-ubuntu-16-04

TL;DR: In Ubuntu 14.04, If you change a static IP address in /etc/network/interfaces and apply the changes with ifdown and then ifup command everything works fine. But this sequence is not working in 16.04. What is the best alternative?

In ubuntu 16.04, after changing interfaces file and ifdown/ifup sequence, ip addr show <device> command shows both old and new static IP addresses for <device>. I used -v (verbose) argument with ifdown/ifup in both ubuntu 14.04 and 16.04. The difference was in ifdown. In ubuntu 14.04 ifdown executes this command:

ip -4 addr flush dev <device> label <device>

While in 16.04:

ip addr del <ip-address-in-network-interfaces>/<subnet> dev <device> label <device>

So I figured out, in 16.04, If I first run the ifdown command. Then change the IP address in /etc/network/interfaces file and then use the ifup command to bring the interface up again, the old IP address will be deleted correctly.

Another solution is running the ip addr flush command before ifdown/ifup:

ip addr flush dev <device>

It seems that I already answered my question, but I want to know what are the alternatives and what is the best solution to change a static IP address in Ubuntu 16.04?

How to disable upgrade/update of selective packages permanently? https://askubuntu.com/questions/781651/how-to-disable-upgrade-update-of-selective-packages-permanently

I read this Q&A about How to prevent updating of a specific package?

But, I would like to disable/prevent update of a lot of packages, how can I do this efficiently?

The above given method works( as shown in image below), but it's hard to find the names of packages that exactly apt-mark understands. See the screenshot below, I need to disable or put on hold all of these except a few.

The software updater pops up many times (I know i can skip it always), but I am on low bandwidth and can't update each and every package. And I hardly use them, e.g. Thunderbird, simple-scan, music player.

It would be very good, if this software-updater had a option to disable update of a package by just right-clicking or some other way.

Additional Drivers for NVIDA Quadro K620 Required for Ubuntu Installation https://askubuntu.com/questions/697344/additional-drivers-for-nvida-quadro-k620-required-for-ubuntu-installation

I just purchased a new Dell computer for my work which has a NVIDIA Quadro K620 (The salesman assured me that it would work on Ubuntu which it does with installation of additional drivers, I've been able to do this from the terminal).

However, the problem is I can only get this working on 15.10 only and not on lower versions, albiet versions 15.04 and 14.04 are the that are compatible with my programs I need at the workplace.

In an attempt to install from a Flash Drive (USB), The Ubuntu 14.04 it says that the graphics card is not compatible and I need to download drivers and asks to run the initial installation in low graphics.

But when I do run in low graphics the screen turns black and does not proceed.

For 15.04 on boot up it gets to a login screen which I use the User Name and blank password to proceed to an installation page. For this one it stays black and the speaker plays the Ubuntu sound over and over as if it is stuck on a loop.

I was able to install 15.10 with some unexpected text problems but when I installed the additional drivers from the terminal this was fixed and it is working great.

The problem comes with my work programs, they are not compatible and have not been tested for Ubuntu 15.10, and I can't install the programs without GCC header problems.

I have installed these programs on multiple releases of Ubuntu with no problems on other computers, this is the first time it does not work for me.

In my opinion, I think that there are two solutions to this which I need help getting to.

  • Install Ubuntu 15.10 then downgrade to 15.04, but the forums I've read on this say to do a fresh install.

The other option (preferred) is

  • During the boot from Thumb Drive (USB) if there is a way to get to the graphics drivers via terminal and install them before installing Ubuntu 15.04, or to install Ubuntu via terminal from the Thumb Drive (USB)?

Does anyone know how the correct method to do so and what is the best way to solve this problem?

Unfortunately, I don't know how to get the graphics card working without having ubuntu installed.
