Swapping from an AMD to an NVIDIA GPU

[Kobold]

I never did a swap for myself…

I just want to throw my 2cents, i hope it helps.

I would probably swap to LTS kernel 6.6 since 6.9 makes problems with nvidia and required additional grub commands (at least for Wayland).

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.

Create a timeshift snapshot before you changing anything.

Get a Manjaro USB Bootstick ready, just in case that you can still boot and can get connection to the community, if you don’t have a second device.

Since i don’t know which “sudo mhwd -a pci nonfree 0300” installs.

You maybe need nvidia-utils and nvidia-settings…

Please take my information with a grain of salt… since i don’t have first hand experience around this topic.
