Update broke Plasma Wayland Session

I am using KDE Plasma with the Wayland session, nvidia drivers.
After performing this update, I can get to the login screen of sddm. If I login as the Wayland session, I get a black screen and the only way out is to reboot. If I login as the X11 session, I get the splash screen and boot as normally.

Re: Update broke Plasma Wayland Session

Does it work again after you downgrade linux and nvidia?

If you want to help get to the bottom of the problem, yes.

I had the same issue and things are back to normal after downgrading the kernel and Nvidia version. Downgrading the Nvidia version alone did not fix the issue.

Re: Update broke Plasma Wayland Session

I was able to boot again to the Wayland session by downgrading to one version earlier:
linux-6.11.1.arch1-1  linux-headers-6.11.1.arch1-1  nvidia-560.35.03-9  nvidia-utils-560.35.03-4  virtualbox-host-modules-arch-7.1.2-3

Re: Update broke Plasma Wayland Session

Can you try to pass  `nvidia_drm.modeset=1` and `nvidia_drm.fbdev=1` to the Kernel Parameters?

(Please do not pass it to the module parameters, otherwise the patch from the "linux" kernel does not work https://github.com/archlinux/linux/comm … 78a9411924

Re: Update broke Plasma Wayland Session

I tried adding both of those parameters to no avail before I rolled the version back.

Adding KWIN_DRM_NO_AMS=1 to /etc/environment did allow me to reach my desktop but introduced a lot of jitter/stutter

Could you give the output of cat /proc/cmdline ?

Re: Update broke Plasma Wayland Session

I see the issue. On the kernel side following workaround was not applied, which could maybe introduce the issue: https://github.com/archlinux/linux/comm … 78a9411924

If you get the blackscreen with the "_" you can workaround it with:

CTRL + ALT + F3 and then go back with CTRL + ALT + F2 or F1

Re: Update broke Plasma Wayland Session

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

Please also use then the "nvidia-dkms" package.

Re: Update broke Plasma Wayland Session

Can you try to pass  `nvidia_drm.modeset=1` and `nvidia_drm.fbdev=1` to the Kernel Parameters?

(Please do not pass it to the module parameters, otherwise the patch from the "linux" kernel does not work https://github.com/archlinux/linux/comm … 78a9411924

I am a bit confused by these kernel parameter. I some places I read people that one should pass `nvidia-drm.modeset=1` and `nvidia-drm.fbdev=1` and then I read here what you recommend. What is the correct way `nvidia-drm` or `nvidia_drm`?

Re: Update broke Plasma Wayland Session

I ran into the same problem after updating.

I can confirm that setting `nvidia_drm.fbdev=1` in addition to the already set `nvidia_drm.modeset=1` fixed the problem.

Is this something that needs to be done from here on out (edit arch wiki) or is this a bug report?

With fbdev=1 I loose the Linux console. Does the console still works for you?

Thank you,

Same here. Lost the console as well. I added fbdev and modeset in the grub file. Is there a way to get it back?

Re: Update broke Plasma Wayland Session

I added nvidia_drm.fbdev=1 to my grub config in /etc/default/grub and it fixed the problem. Just to confirm, did you remember to run `sudo grub-mkconfig -o /boot/grub/grub.cfg` after editing?

I got back the console by removing fbdev (I was using modeset already).

For the moment I'm using X instead of Wayland.

Re: Update broke Plasma Wayland Session

For me the nvidia-dkms 560.35.03-5 package update fixed the Wayland + Plasma problem.

I managed to get Wayland running with console by setting nvidia_drm.fbdev=0 in the kernel parameters and copying this file into /lib/udev/rules.d/

Is there a different way to get the console back without copying a random udev ruleset from ubuntu?
