Black screen after fresh Manjaro installation

[Kobold]

Do you can still see a mouse cursor when you have a black screen?

Do you see your Login before the screen goes black?

It could maybe the plymouth bug, when you can’t even see login screen.

Option1:

Open /etc/default/grub and remove the word splash & quiet from the Grub command line.

Then save the File and use this command:
sudo grub-mkconfig -o /boot/grub/grub.cfg

In addition you can also remove plymouth hook from /etc/mkinitcpio.conf

Then save the File and use this command:
sudo mkinitcpio -P

Option2:

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.
