Is there an existing issue for this?

  • I have searched the existing issues

Are you using any gamescope patches or a forked version of gamescope?

  • The issue occurs on upstream gamescope without any modifications

Current Behavior

When attempting to run gamescope -- vkcube from a VT under NVK on my 4090 rig, gamescope fails to launch w/ KMS unless you specify --backend sdl. Including logs below both with and without the --backend sdl argument.

Steps To Reproduce

Under NVK:

  1. switch to a VT/TTY
  2. run gamescope -- vkcube

note failure to launch a window

  1. try gamescope --backend sdl -- vkcube

this should launch a vkcube window after a second or two

Hardware information

- Distro: Fedora 41 (KDE Spin)
- CPU: Intel Core i9-13900K
- GPU: NVIDIA GeForce RTX 4090 [AD102/NV192]
- Driver Version: Mesa 24.3.3

Software information

- Desktop environment: KDE Plasma 6.2.5
- Session type: Wayland
- Gamescope version: gamescope version 3.16.1-35-g19dc18e (gcc 14.2.1)
- Gamescope launch command(s): `gamescope -- vkcube` and `gamescope --backend sdl -- vkcube`

Which gamescope backends have the issue you are reporting?

  • Wayland (default for nested gamescope)
  • DRM (default for embedded gamescope, i.e. gamescope-session)
  • SDL
  • OpenVR
