Is there a utility that displays or outputs the GPU temperatures on recent-ish nvidia GPUs and which doesn't rely on using the nvidia driver?

I run the nouveau driver, therefore nvidia-smi does not work, and the GPU monitor solutions I've found all rely upon it. lm-sensors apparently does not work with modern nvidia hardware.

Ubuntu 24.04.3 Dell T7910 3080ti FE (and sometimes a 2080 is installed)

I cannot believe that since version 20, Ubuntu has a LOT of issues on the network and it keeps being delivered that way. Does anyone know why?

I've spent the past 2 days trying to fix this alone, but it hasn't worked. my display says it's in 1024x768 when it should be at 1920x1080, and it was until 2 days ago. I have tried everything online and nothing has worked. Done xrandr addmode 1920 etc.., things with ctr, but nothing has worked. I genuinely don't know what else to do. I'm really new to linux so I'm sorry if the question isn't very clear. I'll past some things below

~$ xrandr --size 1920x1080 Failed to change the screen configuration! ~$ xrandr -q Screen 0: minimum 16 x 16, current 1024 x 768, maximum 32767 x 32767 None-1 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 270mm x 203mm 1024x768 59.92*+ 800x600 59.86

If you need any other info please let me know. This isn't all I've tried but I've tried a lot and had to clear the terminal eventually so I've lost most of it.

I recently installed Ubuntu 24.03.3 LTS on a new bought Lenovo IdeaPad 5 2-in-1 14IAL10, alongside Windows 11. Everything worked fine (except the Realtek sound card, but that's another issue) until after two days the bootloader didn't show up anymore. It's not listed in the bios either. The only option there is the Windows bootloader. I can still log in the Windows 11 partition, but not anymore into Ubuntu. With an Ubuntu live edition I downloaded "Boot repair" and got the report under https://paste.ubuntu.com/p/JhZQ9w8JSV/ Does anybody have an idea what to do? Thanks for input on the issue.

We currently are using a network booted PXE cloud-init based auto installations of Ubuntu 20.04 LTS that allow us to automate the installation of Ubuntu onto a number of workstations (if needed). In our environment, we also have a Microsoft SCCM server that automates the installation of Windows onto a number of workstations.

Right now, we have to keep these environments separated by VLANS & DHCP Scopes as the DHCP options that point to the TFTP server are different for Windows and Linux.

What I was wondering, is it possible to somehow combine these into a single PXE server giving us an option to image with Windows or Linux. Choosing the Windows option will boot into the WinPE environment needed to work with SCCM, and Choosing the Linux option will proceed with the Cloud-init autoinstall version of Ubuntu 20.04.

If this is possible, does anyone have a working version of a config file that they can share and maybe answer a few high level questions on what it is I need to configure in on PXE server to enable this?

I wanted to install Steam on my laptop with Ubuntu 24.04. I installed it via snap, but something went wrong, and I decided to reinstall Steam. While removing Steam the process got stuck and I closed the terminal and tried to remove Steam again, but I got an error snap "steam" has "remove-snap" change in progress. I tried snap abort 26 (Steam removing process), but after rebooting I got the same error.

I tried running systemctl list-units | grep snap.steam to find any related units, and tried stopping and disabling them, but that didn't work.

I also tried sudo snap refresh core, but that didn't work either.

I can connect to the internet through ethernet but I can't seem to find wi-fi connections, even though there is wifi in our home

this is the output of the wireless-info script I downloaded from another question a year ago

In X11, I can run xkill, and select an window that I want to close.

I want something similar in Wayland. The other command line options like pkill or kill involve getting the exact app name or the PID of the process.

I just want to click on a Window and close it instead. How to achieve this in Wayland?

This explains how to do this in KDE Plasma running Wayland. What about regular Ubuntu with GNOME?

Any suggestion on how to fix?

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 intentional alteration/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?

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?

My searches indicate that this is commonly caused by python and some of its modules not being up to date with respect to each other.

But as far as I can tell, they are in sync:

What am I missing?

I routinely prepare screenshot graphs from my running activities as logged on 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:

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...

For a few weeks I have been getting timeouts when trying to update snaps from snapcraft.io. So I have been googling, and one of the fixes was to remove all snaps, remove snapd, then reinstall snapd and the various snaps.

I am trying to force a user to change their password every time they log in. For example, if it is their first login, they will be asked for a new password, and when they log out and try to log back in, they will have to change their password again.

The machine crashed (system frozen) while using GIMP. The only error showing up in the logfile is NOHZ tick-stop error: local softirq work is pending, handler #40!!!

System is up-to-date (actually a relatively fresh upgrade to noble)

Any advise?

I am using Ubuntu 24.04 on my Dell XPS laptop. I am experiencing an issue where image previews (thumbnails) are not displayed on my desktop. Instead I see generic icons for image files:

Steps taken to troubleshoot:

1. Checked File Manager Settings:

   • I opened Files (Nautilus) and navigated to Preferences.
   • Under the Performance tab, I confirmed that the option to show thumbnails is set to All files.

I would appreciate any assistance in troubleshooting this issue further. Are there additional steps I might have missed, or is this a known issue with a specific fix?

This is my first dip into linux and I've hit my first roadblock. The Bambu Studio software for my 3d printer is only available as an appimage. I made it an executable file in properties and it won't run from command line or double click. Tried moving to desktop and same deal. No errors, it just does nothing. Did the chmod a+x command I found and that gave no errors. Still nothing.

Ubuntu 24.04 LTS

Thanks for any help!

I don't know what SELinux is, but semanage isn't installed so I don't think that is the problem.

I've restarted the machine and server daemon since configuring everything.

I saw a share from the computer on a separate linux device after starting the server daemon the first time. However, I was never able to access it and am no longer seeing it.

I'm a PHP web developer I have some errors with new version of ubuntu, I was Installed new version of Ubuntu (22.10) but when I installed php 8.2 version I can't know how to install different version of PHP.

For example I tried to install php 8.0, 7.4, 7.0, 7.2 , ... but nothing happened I was tried many ways, please if someone know how to install multiple versions in ubuntu 22.10 ask me.

Thank You.

Xkill is a utility program distributed with the X Window System that instructs the X server to forcefully terminate its connection to a client, thus "killing" the client.[1] When run with no command line arguments, the program displays a special cursor (usually a crosshair or a skull and crossbones) and displays a message such as

Select the window whose client you wish to kill with button 1 ...

If a non-root window is then selected, the server will close its connection to the client that created that window, and the window will be destroyed.

I would like to achieve the same behavior for wayland windows, if possible.

PS: I am on Kubuntu 21.10 running a wayland session, but would prefer something DE agnostic.

I'am trying to get Maven running. I have installed JDK and Maven. Thus I have been trying to set the Java_home variable for three days now, I cannot get it working.

I have followed the instructions of another askUbuntu Topic:

• How to set JAVA_HOME for Java?
• How to set Maven home PATH on Ubuntu as User

This doesn't work. Not any explanation explains how to set the path, they rather give examples how to set their path.. So I have no idea whats wrong with mine, it is the location to the file in the etc/environment.

I installed maven by downloading the correct latest version on the site. Extracted and installed it in opt directory using known sudo-commands.

I created the maven.sh file myself, since there wasn't a file like this in the profile.d directory. You can see how I set that in the cat output and the picture below.

The Java_Home set in my etc/environement though is: JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64";This used to be /usr/opt/jdk-13.0.1 (which you will see the terminal give back the first time), because thats how I thought It needed to work according to explanation how to install Maven.

When I source my maven.sh, I get the right mvn -version in the terminal. When I close terminal, I have to source it again.

Here my terminal feedback on the versions, rember that after the first 3 commands (version -java, -mvn and echo) I source my maven.sh file manually:

It should work on Ubuntu based on this post on winehq.org. How to fix this error?

I have seen several putative answers to my question, but none of them work.

Generally I keep the touchpad switched off, since it seems to play hell with the pointer jumping about into unwanted places. But once in a while my mouse freezes up and I would like to be able to use the touchpad to get something or other going. The problem is that enabling the touchpad seems to require the use of the mouse, and if this is frozen then I am stuck. I would like to enable the touchpad from the command line. As I said I have seen several suggestions, but none of them work.

(1) xinput list

followed by xinput --list-props nn

where "nn" is the ID for "SynPS/2 Synaptics TouchPad" given by the initial "xinput list".

Problem: there is no such item given when I do "xinput list".

(2) Use "Fn+F1" to toggle the touchpad, after having done

sudo apt install xserver-xorg-input-synaptics

When I do this "sudo apt install" manoeuvre I get told that "xserver-xorg-input-synaptics is already the newest version".

However "Fn+F1" has no effect at all.

(3) synclient TouchpadOff=1 to disable the touchpad and synclient TouchpadOff=0 to enable it.

No error messages given, but nothing at all happens.

Any other ideas?

Note that my "TouchPad Indicator" on my top menubar works just fine, but of course I can't use this when I actually need to, which is when my mouse is frozen. Catch 22.

I have now had two responses, one from Stephen Boston, suggesting that I look at function keys other than F1 (one with "Square with a diagnoal line through it -- maybe?"). No such key on my keyboard; my laptop is a Dell "Latitude E7470" (???). tried all of the function keys, one at a time, holding down the "Fn" key and pressing a function key. Nothing at all happened with any of them, except that "Fn-F11" toggles an expansion of the current window. No enabling of the touchpad eventuated.

The other response was from "PRATAP" who suggested that

https://askubuntu.com/a/1140700/739431

might be a workaround. I tried to do what this link suggested:

xmodmap -pke | grep TouchpadToggle

produced

keycode 199 = XF86TouchpadToggle NoSymbol XF86TouchpadToggle

So I then did

xmodmap -e "keycode 199 = XF86TouchpadToggle"

in accordance with what I understood the instructions to be.

After doing this I tried "Fn+F5" --- not a sausage --- and "Fn+F1", likewise.

I don't understand step 2 of the instructions "check the symbol on keyboard which is given for Toggling of Touchpad.. in mycase it is on F5 #Change F5 with your key on keyboard".

As far as I can see NO symbol on the keyboard is "given for Toggling of Touchpad".

If I do

xmodmap -pke | grep F5

I get

keycode  71 = F5 F5 F5 F5 F5 F5 XF86Switch_VT_5

which is exactly the result in the given example.

So I then tried (hammer and hope; no clue what is going on!)

xmodmap -e "keycode 71 = XF86TouchpadToggle"

The first time I tried "Fn+F5" the touch pad seemed to be toggled on, and I thought I had a success. But it wouldn't toggle off again. I turned off the touchpad using the icon on the top menu bar. Then "Fn+F5" had no effect thereafter.

This is exasperating.

And the exasperation continues. The

synclient TouchpadOff=0

construction (recommended by "bistoco") does NOT work for me. (I also tried it with a lower case "o" in the "Off"; same result.)

Why do computers pick on me???

I have one 4K monitor (3840 x 2160) and two QHD monitors (2560 x 1440) and I want to have them side by side. This is currently not possible though, since the horizontal virtual resolution required for this is 8960 pixels (3840+2560+2560) but the maximum (horizontal) virtual resolution set by the X server is 8192 pixels. Is there any way to increase the maximum virtual resolution past 8192x8192 pixels?

What I have tried up to now:

• I do not have a xorg.conf file - I tried manually creating one myself including the "Display" sub-section and setting a different "Virtual" value in there, rebooted, nothing changed.
• Tried various xrandr command variations with the --fb and/or --panning parameters set to the desired maximum (8960x2160+0+0), again to no avail. (output: xrandr: screen cannot be larger than 8192x8192 (desired size 8960x2160))

I did read a claim somewhere (EDIT: here) that Intel's graphics processors do not support greater virtual screen resolutions than 8192x8192 pixels (my system is using a Core i7-6700HQ CPU with the Intel HD Graphics 530 graphics processor), but I unfortunately have been unable to confirm this information - hopefully this is not the case.

EDIT: It is indeed probably not the case:

#: glxinfo -l | grep GL_MAX_TEXTURE_SIZE
GL_MAX_TEXTURE_SIZE = 16384
GL_MAX_TEXTURE_SIZE = 16384

My xrandr output (I currently have the third monitor positioned bottom-right, hence the 8192x3600 virtual screen resolution):

I'm trying to compile a project that has a dependancy on gettext 0.19.3. I currently have 0.19.2 installed.

I've tried:

• sudo apt-get install gettext
• sudo apt-get install autopoint
• sudo apt-get install --only-upgrade gettext
• sudo apt-get install --only-upgrade autopoint

None of those commands will cause gettext to update. The terminal always says

gettext is already the newest version
0 upgraded, 0 newly installed, 0 to remove and 138 not upgraded.

How do I install 0.19.3 or 0.19.4?

Before, I was using Gnome desktop on Ubuntu 14.04. Then, I installed Xubuntu desktop and, just recently, when I login it does not work. I don't know what's wrong.

When I drag something, its' image repeats many times (see below) and stays on the desktop and nothing works. Gnome is still ok.

How can I restore Xubuntu desktop to its' defaults?

I installed MATLAB on a new Ubuntu 14.04 installation. I don't get any errors, but when I try to run it in the terminal with the matlab command, the screen doesn't advance past the MATLAB logo:

I'm not sure what to do because it's not giving me any errors. I've already tried reinstalling MATLAB. Any advice would be appreciated as I'm unfamiliar with the Ubuntu environment.

I have Broadcom bcm43224 wifi card with proprietary broadcom sta driver. At home wifi connection works well, but in the office when I ping some resource there is a lot of loss packets and I cant browse websites.

I have tried another way to check internet connection - download file with wget.

wget google.com - very slow speed

wget -4 google.com - normal speed

So, it seems that the problem is with the ipv6 configuration at the office, can I force my wifi connection to use only ipv4 and completely ignore ipv6 ?.
