Change Login Resolution in Xubuntu 13.04?
I just installed Xubuntu 13.04 and enabled the drivers from fglrx-update for my Radeon HD 5400 Series video card. However, once the login screen comes up, I get a warning from my monitor about the resolution not being supported.
I can change the resolution once I’m logged in, but I keep getting the same warning when I boot up the computer and try to log in.
Most guides/sites I could find about this problem suggest editing xorg.conf, but that file is not present on my system. I tried the solution in http://www.bingshui.org/tech/defining-display-resolutions-in-xubuntu-12-04/ but this caused the system to freeze right before the login screen comes up, and I had to delete the file created when trying that solution.
How to change the screen resolution for the GDM login screen? suggests editing /etc/gdm/Init/Default, but again, there is no gdm directory in /etc.
Is there a way to fix this?
