Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

Previous session working 100% fine. Then I do the followinig upgrades:

[2024-10-01T09:04:01-0700] [ALPM] upgraded linux (6.10.10.arch1-1 -> 6.11.1.arch1-1)
[2024-10-01T09:04:02-0700] [ALPM] upgraded linux-headers (6.10.10.arch1-1 -> 6.11.1.arch1-1)
[2024-10-01T09:04:02-0700] [ALPM] upgraded nvidia-utils (560.35.03-3 -> 560.35.03-4)
[2024-10-01T09:04:03-0700] [ALPM] upgraded nvidia (560.35.03-6 -> 560.35.03-9)
[2024-10-01T09:04:03-0700] [ALPM] upgraded qt6-base (6.7.3-1 -> 6.7.3-2)

System completely fails to reboot. Blank screen when after entering wayland session. Usually when this happens it has something to do with HDR, however disabling HDR does not fix the issue so it seems unrelated. Plus journalctl does nto show any graphics rendering related errors.

After downgrading these packages to previous version, everything works fine again.

Same problem here. Downgrading Kernel and Nvidia packages fixes the issue.

Edit: adding nvidia_drm.fbdev=1 kernel parameter solved the issue for 6.11.1 kernel.

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

Same problem for me. I was able to switch to X instead of Wayland using the Desktop switcher and continue working. Will wait for upgraded packages to fix the broken Wayland after this update.

Please try following, this should fix the issue, with above patch pulled in:

```

sudo pacman -U https://pkgbuild.com/~ptr1337/kernel-testing/simplefb-skip/linux-6.11.1.arch1-2-x86_64.pkg.tar.zst https://pkgbuild.com/~ptr1337/kernel-testing/simplefb-skip/linux-headers-6.11.1.arch1-2-x86_64.pkg.tar.zst[/url]

```

https://github.com/archlinux/linux/comm … 78a9411924

Please use this together with nvidia-dkms.

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

@Fusion916 Thanks, downgrading the packages you mentioned did the trick. I am using hyprland and nvidia-dkms.

Thank you for your suggestion, adding nvidia_drm.fbdev=1 kernel parameter solved the issue for me too (without downgrading any packages).

Still, I get the following in the logs:

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

Unfortunately adding nvidia_drm.fbdev=1 kernel parameter generates another issue for me: I lose the Linux console completely.

Back to X for now.

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

Had the same problem and *mostly* the same solution. Downgrading QT6 broke SDDM, so I had to update that back to 6.7.3-2.

I did not need to downgrade qt6-base. See parallel thread: https://bbs.archlinux.org/viewtopic.php … 0#p2199950

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

Like others I also downgraded the kernal and nvidia drivers to get a stable system back - after disabling the phantom fb screen in hyprland config, hyprland was running at very high cpu usage prior to this...

I noticed nvidia-dkms 560.35.03-5 came out of testing today so did a system upgrade.  Unfortunately I still have the very high cpu hyprland usage... any thoughts?  EDIT fbdev and modeset are enabled.

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

For me the nvidia-dkms 560.35.03-5 package has solved the Wayland black screen issue. i do not use Hyprland, but Plasma, and do not see (using top) any abnormal CPU consumption.

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

Is this issue fixed now? I got an update this morning of the nvidia package and etc. and I can see that the gitlab issues have been closed but I don't see what solution is to enabling "nvidia_drm.fbdev=1"?

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

The issue is fixed (for me). I updated this morning and rebooted without issues. I don't have fbev as a kernel parameter so its not needed (for me).

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

Also fixed for me, linux 6.11-2 & nvidia-open-dkms 560.35.03-12 updates today have removed the performance problems.

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

I just removed fbdev kernel parameter from my grub file and I confirm that my KDE+Wayland+nvidia session runs fine. But I have lost the console still. I have run 'grub-mkconfig -o /boot/grub/grub.cfg' after I changed '/etc/default/grub'.

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

linux 6.11.2.arch1-1
nvidia-dkms 560.35.03-5
wayland 1.23.1-1
kwin 6.1.5-2
plasma-desktop 6.1.5-1

+

no related kernel parameters (defaults to modeset=1 and fbdev=1)
/sys/module/nvidia_drm/parameters/modeset = Y
/sys/module/nvidia_drm/parameters/fbdev = Y

=>

KDE + Wayland works but the console is lost

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

Had the same problem. Fixed by switching to nouveau drivers and downgrading linux and linux-headers. Switching to nouveau was probably not necessary.

Re: Upgrade this morning completely broke KDE plasma + Nvidia (Wayland)

I am on the closed source nvidia drivers and the latest update works fine again with hyprland too. I made no changes to configs or kernel parameters at any point, and did not switch to nouveau.
