Nvidia display settings reset after logging in

[Kobold]

Yeah that’s normal on a fresh iso “yet”.

Try out LTS 6.6 with Wayland or check this out if you want to use newest Kernel 6.9:

@Yochanan

No plasma interface with kernel 6.9 + Nvidia gpu + Wayland

If you encouter a black screen with no inteface after login in, it’s probably a problem with simpledrm loading.

To solve it add nvidia_drm.fbdev=1 to /etc/default/grub
in the line begining with GRUB_CMDLINE_LINUX=" .
Verify that you also have nvidia_drm.modeset=1 in the same line.
Then exec sudo update-grub

Also, verify that you have nvidia_drm in /etc/mkinitcpio.conf in the MODULES= or HOOKS= line.
Exemple :

MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)

If it was not present, then run sudo mkinitcpio -P after adding it.
