Xorg failed to create screen resources after enabling nvidia_drm.modeset

Hello, I am using an optimus laptop with a GTX 1060 using the proprietary drivers. I need to use nvidia_drm to make external screen work on Wayland (using KDE 5.27). To enable it, I simply added nvidia_drm.modeset=1 to the kernel parameters.

But after setting this parameter, I can’t reach SDDM anymore, it stays on a black screen with a blinking console cursor. If I switch to a TTY and type startx, I get the error (EE) failed to create screen resources(EE).

Wayland works just fine, I can switch to a TTY and type startplasma-wayland to boot up a wayland session, and external monitors work thanks to the nvidia_drm.

I looked through the arch wiki at NVIDIA/Troubleshooting and tried adding



Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BusID          "PCI:1:0:0"
EndSection

to /etc/X11/xorg.conf.d/10-nvidia.conf

I also tried adding

xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

to /usr/share/sddm/scripts/Xsetup as explained in the arch wiki at /NVIDIA_Optimus but still no luck.

I don’t really care about X11 as Wayland can replace it for everything I need. I can always disable nvidia_drm and start the x session if I ever need it. Using a workaround to at least make SDDM work would be fine.

Anyone could help me on this please? (I know, yet another nvidia optimus issue…)

is nvidia-settings installed ?
check

pacman -Qs nvidia-settings

if not add

sudo pacman -S nvidia-settings

It got removed in latest updated and seeing how useless the settings are I did not reinstall it. Now I have, but still nothing changed.

6

have you reboot ?

Yes I rebooted and started the settings app in an X11 session, then rebooted again using the nvidia_drm param
