Wayland Nvidia 555 black screen after update

Help

Gentoo 2.15 x86_64

NVIDIA GeForce RTX 4070
Nvidia Drivers 555.58.02

Hi all,

I recently updated from Plasma 6.1 to 6.1.2. From lightdm, when I try to boot into Plasma Wayland, I get a black screen with a blinking cursor. From here, I can enter a tty. It used to work perfectly before the update. The X session still works.

cat /sys/module/nvidia_drm/parameters/modeset and cat /sys/module/nvidia_drm/parameters/fbdev both return Y.

In ~/.config/kwinoutputconfig.json, both "highDynamicRange" and "wideColorGamut" are set to false, as I have read there are issues with HDR as per Bug 488941

I use OpenRC so journalctl is unavailable to me. If it’d be helpful to post some logs, please let me know how I can access them.

Some help would be much appreciated. Thanks!

Booting into Wayland KDE from SDDM as opposed to LightDM did the trick. Cheers

found the fix

Ensure that you do not have a manually installed version of libnvidia-egl-wayland1 (especially if you are going to install version 555+ of the Nvidia driver). The driver already includes it as stated

sudo apt remove libnvidia-egl-wayland1
