Public bug reported:
Extended test case:
Prerequisites: A laptop with nvidia hybrid gpu
Latest repo nvidia drivers installed (384
Prime sync not yet enabled
While on the nvidia driver profile boot up, login screen should only offer the
xorg session.
In nvidia-settings switch to Intel, restart (one must *always restart with gdm3*
What happens:
At log in both the wayland & xorg session options are present (correct behavior
Switch back to nvidia in nvidia-settings
Enable prime sync (how below
Restart
What happens:
At login only the xorg session is presented (correct behavior
Now again open nvidia-settings, switch to Intel
Restart
What happens:
At log in only the xorg session is present (incorrect behavior
What should happen:
Both the wayland & xorg sessions should be present
To enable prime sync:
sudo nano /etc/modprobe.d/zz-nvidia-modeset.conf
Insert this line, save:
options nvidia_384_drm modeset=1
Run
sudo update-initramfs -u
