Changing graphical login screen refresh rate on Lenny

lbdu · 06-26-2009, 02:43 AM

Is there any way to change the resolution and refresh rate of the graphical log on screen in Lenny? I have the right resolution and refresh rates set for after I log in but I don't know which file to edit to make Lenny use the right settings for the log on screen.

You must edit /etc/X11/xorg.conf to tell GDM what resolution to use or it will just guess. Yes, changing the resolution in your GNOME session only applies to your session.

For example at the bottom of the file, add in a Modes line like this:

SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768"
EndSubSection
EndSection

The refresh rate is defined in the Monitor section of this file with HorizSync and VertRefresh.
