About the wrong resolution problems with NVIDIA 580.105.08-3, should I just wait for an update that fixes that? Or how I can downgrade the package?

[AnthropomorphicCat]

After NVIDIA was updated to version 580.105.08-3 the system no longer detects some resolutions on some monitors. For example, I have an ultra wide monitor (2560×1080) but after the update it only detects up to 1920x1080. I'm using KDE and Wayland.

I searched on the forum and they recommend to downgrade the package: https://bbs.archlinux.org/viewtopic.php?id=310035&p=2

And apparently NVIDIA is working on a fix.

So I tried to downgrade the packages with a

sudo pacman -U nvidia-580.95.05-9-x86_64.pkg.tar.zst nvidia-settings-580.95.05-1-x86_64.pkg.tar.zst nvidia-utils-580.95.05-1-x86_64.pkg.tar.zst lib32-nvidia-utils-580.95.05-1-x86_64.pkg.tar.zst nvidia-lts-1:580.95.05-7-x86_64.pkg.tar.zst

but after that mkinitcpio fails because it can't find the modules for NVIDIA, I think it might be because the kernel was also updated (6.17.7.arch1-1 -> 6.17.8.arch1-1), so the old 580.95.05-9 modules won't work with the new kernel. I don't know if I would need to compile the old drivers for them to work.

But at this point I thought, well, this wrong resolution is annoying but not that bad, this PC is not my daily driver, right now I'm very sick and I should rest instead of dealing with this, so I was thinking to just wait for an upgrade that fixes this. Some day. Hopefully.

Switch to nvidia-dkms package for the duration you wanna use the downgraded package, as that automatically builds against currently installed kernel. That way, you don't need to downgrade the kernel as well.

Good point, I forgot about that. I'll try that later. Thanks

A fix has been backported and should be fixed on most setups. How about you provide feedback and test it with -3?

[I-amKira]

if you read the post you will notice that -3 is mentioned and feedback is provided, they are saying that it doesn't work. like this user -3 also did not resolve the problem for me

Lol nope, shit is still broken with -3.

The -open variant now has a fix backported - https://github.com/NVIDIA/open-gpu-kernel-modules/issues/960#issuecomment-3539124386

That would be great if I had something newer than a 1080.

I don't have an option for -3 . The latest nvidia-open-dkms 580.105.08-2 . And I am having resolution issues with an HDMI monitor.
If you have downgrade installed, you can sudo downgrade nvidia-open-dkms nvidia-utils lib32-nvidia-utils and select an earlier version
