GAMESCOPE + TTY + NVIDIA = Failed to initialize output

[miramax001]

Hi,

I'm trying to launch STEAM from TTY

CMD:

STEAM_MULTIPLE_XWAYLANDS=1 gamescope -W 1920 -H 1080 -r 60 -e --prefer-vk-device 10de:24e0 --xwayland-count 2
-- steam -gamepadui -steamdeck

OUT:

vblank: Using timerfd.

Failed to initialize output

• gamescope: gamescope-nvidia:3.14.0-1
• NVIDIA: 550.40.07 (tkg version)
• Kernel parameters: nvidia-drm.modeset=1 nvidia_drm.fbdev=1

Anyone know out do I fix this?

Regards

nvidia-drm.modeset must be set as a kernel launch parameter, not a sysctl.d thing.

You should also probably remove nvidia_drm.fbdev=1. IDK what that is meant to do but it sounds like it could conflict.

(also isn't the module prefix nvidia-drm and not nvidia_drm, its probably not doing anything anyway...?)

hi,

It's as kernel launch parameter:

cat /proc/cmdline

BOOT_IMAGE=/@/boot/vmlinuz-linux-zen root=UUID=xxxxxxx rw rootflags=subvol=@ quiet loglevel=3 nvidia-drm.modeset=1 nvidia_drm.fbdev=1 ibt=off

I'm facing this issue on 535.43.25 vulkan beta

I'm having this issue on Arch Linux with a Framework 16 (AMD GPU). Most things just work on this computer, with this notable exception.
