Hi,
I have Intel GPU and NVidia one (NVidia optimus laptop) — GTX970M.
If I start Plasma Wayland session on my laptop (openSUSE Tumbleweed) with
/etc/vulkan/icd.d/nvidia_icd.json
/usr/share/glvnd/egl_vendor.d/10_nvidia.json
disabled, system runs with NVidia power switched off. But XWayland started without NVidia GPU registered, so only Intel GPU works. If I just enable those files and make sudo modprobe nvidia — XWayland kinda sees NVidia GPU, but vulkan can’t initialize it properly and doesn’t work.
If enable those files quit session, run sudo modprobe nvidia — GPU power is switched on and after logging in again — NVidia GPU is working fine under XWayland.
I’d like a way to restart XWayland without restarting while kwin_wayland session (and all apps with it).
Another option is to run second XWayland (DISPLAY=:1 ?), but I think that’s even more complex.
So, is there any way to do this?
