On Plasma/Wayland I get those same settings, however the display is
running on the internal Intel GPU, not on the Nvidia. Even though the
Nvidia kernel modules are loaded, there appears to be no way to access
the GPU. Thus:
$ nvidia-settings
ERROR: Unable to find display on any available system
$ switcherooctl
Device: 0
Name: Intel® HD Graphics 4000
Default: yes
Environment: DRI_PRIME=pci-0000_00_02_0
Device: 1
Name: NVIDIA Corporation GP107 [GeForce GTX 1050]
Default: no
Environment: __GLX_VENDOR_LIBRARY_NAME=nvidia
__NV_PRIME_RENDER_OFFLOAD=1
$ switcherooctl -g 1 nvidia-settings
ERROR: Unable to find display on any available system
If I run Plasma/X11, all of the above works correctly (as it did on F33
of course). IOW, with Wayland the Nvidia GPU is currently useless.
