I'm using gnome under Arch Linux in my laptop with a 1920*1080 monitor on the left of it, I set the monitor as my primary display in GNOME and everything works fine after I log in. However, GDM displays my log-in dialogue on my lap-top screen every time, and I noticed that my monitor was set defaultly on the right side of my laptop. I searched and found someone said mouse's position may have effect, which did not work on me.Can anybody help?
How to let GDM shares monitor configure with GNOME?
