The regression from https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1942789.

It impacts Jammy and Impish so far.

[Steps to reproduce]
1. Find a GPU supports nvidia-390
2. ubuntu-drivers install nvidia:390
3. prime-select on-demand
4. glxinfo

[Expected result]
Shows intel or nvidia drives monitor

[Actual result]
Error: couldn't find RGB GLX visual or fbconfig

Since we are all agree "on-demand" mode as default mode.
Pre-talk with Alberto, on-demand doesn't support with nvidia-390 (no matter RTD3).
We could consider to make it as performance mode and leave a note on nvidia-settings.
I'll prepare some test packages.
