Driver problems with lates kernel update

[oldgeek]

The most recent Linux update (to 6.8.0-79) apparently doesn't like my Nvidia GT 730 propriety driver (470) and automatically switches to the Nouveau driver, which only gives me 1024 X 768 instead of 1920 X 1080. I am running Kubuntu 24.04, using X11. I have gotten around this problem by switching to the previous Linux kernel, but I want to know if this is going to fixed or is the Linux kernel phasing out support for the Nvidia driver I have used for my graphics card? Will I have to get a newer graphics card?

Most likely the nvidia 'shim' module failed to build for the new kernel build - it isn't really a whole new kernel, just a security patch to 6.8.0.

You will very likely face issues in the future OS releases as Nvidia definitely does not support anything past 6.8 for this driver. There will be workarounds but really nouveau should support normal resolutions , supposedly.

The proprietary driver install adds a blacklist for Nouveau, iirc to keep it from loading, so that 1024 resolution seems to me more likely to be from the busted 470 driver.

So try reinstalling nvidia-470 using apt and see if there are any errors.

sudo apt reinstall nvidia-470

This *should* run DKMS to build/rebuild modules for your kernels, but hoping someone with actual Nvidia hardware can chime in on that.

<--Nvidia user, but a much newer card, so I don't use 470

sudo apt reinstall nvidia-dkms-580

works for me.
I have a related question, if I may. Would it be better to use pkcon?

sudo pkcon repair --autoremove
sudo pkcon install nvidia-dkms-580

Would it be better to use pkcon?

No, Pkcon is just using apt (on Deb based systems) so there is nothing fancy it is doing, and the repair option (for database repair) may not even be doing anything (again, on Deb based systems).

OK, I asked because I was told that pkcon update is better than apt upgrade.
Now, I ran into an interesting problem when my system upgraded. My Nvidia was borked, just as the OP first said. All of those commands above are a waste. I finally got it up and running with

sudo ubuntu-drivers autoinstall

Probably a numpty neon user on Reddit?

Nope, Pkcon is the commandline version of what Plasma Discover and Gnome Software use under the hood -Packagekit. This uses various backends to hook into all the different packaging systems in various distros. So it isn't better, or worse, though it hides useful output when there are errors.

As a long time neon user, I could go on a rant about pkcon if I am not careful and calm.

Good find!


Which driver did you have, and which did autoinstall give you, if it installed a different one?

Was there any interesting messaging?

The ubuntu-drivers command is scripting that does use apt to install the driver/run DKMS, among other things. I imagine knowing your card and the driver versions involved might be useful for others seeing similar issues. I would not have thought that the command wouldn't repair anything, just not do much when it sees that the packages are already present.

Things will be sooooo much better when more people are able to use the Open Nvidia driver (the new-ish one that is NOT nouveau)

I tried re-installing driver 470 but a message appeared saying it could not locate the 470 driver. I checked my driver in Settings and discovered I was using a manually installed driver which I didn't personally install. When I checked the driver in Settings with the latest kernel patch, the Nouveau driver was marked.

Well, I had 575 installed. I used ubuntu-drivers to initially install Nvidia drivers. Yesterday, Discover said I had a system update and almost everything was Nvidia based. I did the update, rebooted, and my machine would freeze up if I tried to make Youtube fullscreen. I tried the first of my codes above. I tried installing, un-installing, manually removed files (DO NOT try this at home, kiddies. It's VERY bad practice to manually add or remove stuff from the system).I went and did the ubuntu-driver autoinstall and it started by shutting Nvidia down, removed both 575 and 580, then re-installed 580, built the kernel, recreated the initrid and the boot system (grub, until I can figure out how to permanently delete it without breaking the system), restarted Nvidia and rebooted and I can watch YouTube fullscreen. I'm sold. "#1 Fan" of ubuntu-drivers.
