ThinkPad P1 gen4 with Hybrid-Graphics : black screen [SOLVED]

EnzephaloN · 2024-09-16 12:57:40

Hello

I had to reinstall Arch on my ThinkPad P1 gen4 (has Intel GPU and nVidia A2000 RTX).

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation TigerLake-H GT1 [UHD Graphics] (rev 01)
01:00.0 VGA compatible controller: NVIDIA Corporation GA107GLM [RTX A2000 Mobile] (rev a1)

It works fine with intel-GPU.
But if I install nvidia (or nvidia-dkms or nvidia-open-dkms) drivers, I see no login-screen. Just seeing a black screen with white cursor.
I had mkinitcpio.conf MODULES set and I had grub CMD_Line set. Nothing helped. I also hav symlinked /etc/udev/rules.d/60-gdm.rules to /dev/null
Nothing helped.

/etc/mkinitcpio.conf

MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm)

/etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet resume=UUID=9fdf7113-ab11-4e81-bc3a-557c5fca2a3d acpi_os=Linux nvidia_drm.modeset=1 nvidia_drm.fbdev=1"

udev.rules.de

ls -la /etc/udev/rules.d 
lrwxrwxrwx 1 root root    9 14. Sep 08:53 60-gdm.rules -> /dev/null

Tried "everything" like removing nvidia from mkinitcpio.conf or from grub. Got black screen.

I'm totally confsed, because it was working before and my etc-backups do not show any other configurations.

Maybe you have some help for me?

Best regards

Oh, I think it's my fault. The symlink has to be 61-gdm.rules ! After fixing this, it works!
