[GNOME + GDM] Stopping login services does not stop the desktop environment

To my experience, I always seem to stuck at Warning : Xorg server does not want to stop. when trying to switch. This leads to many issues, including having to manually logging out the DE and restarting the login service when switching to nvidia, and the login service (in this case gdm) crashes when trying to switch back to intel. However, when I first log out of the desktop environment and run the switching script in a virtual terminal, everything works fine and dandy.

Login manager: GDM 3.30.2 Desktop environment: GNOME 3.30.2

Great ! Thanks for testing.

I frankensteined GDM on top of my KDE install to test it, and the results have been…weird.

First, I can’t reproduce your issue. Stopping GDM does seem to stop the X server as well. Maybe that’s because I’m using KDE, I don’t know.

But then, after restarting, everything goes crazy. So far, I’ve had :

• a black screen after restart
• nvidia-drm spamming errors in dmesg
• my wifi applet broke
• even a kernel panic (how the f. is that even possible)

I’m going to test your PR and see if things are more stable with it.
