Are you in charge of GDM? :face_with_monocle:

If so, I noticed a bug:

When changing resolution settings, enable/disable the ā€œAdjust for TVā€ option, when changing orientation, scaleā€¦

~gdm/.config/monitors.xml

The bug:

The screen customizations mentioned above only apply to GNOME desktop, not GDM.

Jā€™ai dĆ©couvert que GDM utilise un autre monitors.xml que le bureau GNOME, qui se trouve ici:
~gdm/.config/monitors.xml (=[admin://]/var/lib/gdm/.config/monitors.xml)

In fact, you just need to replace ~gdm/.config/monitors.xml with ~/.config/monitors.xml, and your GNOME session configuration is applied to GDM.

ā€”> Could you please make it so that this manipulation is no longer necessary? :pray: :blush:

I noticed another display issue with GDM / GNOME desktop

Summary of this topic

The problem:

When I connect a setup of 2 monitors (via a usb-c dock), the screens are detected, etcā€¦ BUT the configuration of the integrated screen of my laptop changes, itā€™s extremely annoying:

I believe GNOME regenerates the monitors.xml every time an unknown display is connected. This forces me to reconfigure the displays every time I connect my laptop to a monitor setup.

Why does GNOME regenerate the entire monitors.xml?

KDE just adds a new screen configuration below everything else. Couldnā€™t GNOME do it like that? It makes the most sense.

Thank you very much for your help! :smiley:
