Bug Description

When I use nvidia-settings GUI to switch to the Intel GPU, I save nvidia settings, log out, and try to log back. But nothing load and GDM restarts.

I have to open a tty and type sudo prime-select nvidia to get a successful login.

Please note the attached files are after that successful login.

I suspect gdm is not calling gpu-manager, which would make it a bug in gdm.
