I wonder if anyone could shed some light on this issue I have. The thing is that my desktop resolution in Gnome is 1280x1024@75, which is perfect. I have set it with the following modeline in xorg.conf:
ModeLine "1280x1024" 135 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync
However, the refresh rate at login screen is 85 Hz, and also the resolution is probably different (it's hard to tell, really, but the login screen doesn't fill up the whole screen horizontally).
So, how can I set the refresh rate and resolution of the login screen?
