Silently fails in Wayland session

[Chris Halse Rogers]

I've got an nvidia/intel hybrid laptop. In a Wayland session nvidia-settings fails silently when started from the shell. When started from a terminal, it prints:

ERROR: Unable to load info from any available system

and then quits.

While I can certainly confirm, what is the use case?
It would seem only useful when in a wayland session to switch from the intel profile to the nvidia one before rebooting to an xorg session. I guess that could save a little time/effort.

[Chris Halse Rogers (raof)]

It's certainly possible to log out, log in to an Xorg session, and then log out again/reboot to switch to NVIDIA. *If* you know that's what you need to do.

Since nvidia-settings silently fails *and* we default to Wayland if possible users who don't know this is what you need to do will find it very difficult to switch back from Intel.

[Doug McMahon (mc3man)]

Currently with hybrid systems a wayland session is presented when nvidia drivers are in use though the user is logged into wayland using the Intel gpu.
So the fact that while in wayland the user can't use nvidia-settings > prime profiles to *actually* switch back to the Intel gpu makes this bug more of an issue.

I see "ERROR: Unable to find display on any available system" when starting with Wayland. Is there and update on this issue?
