My monitor died today. :(
I plugged in an old 14"er that was sitting around, but it doesn't have the capabilities of the other monitor. How can I configure GDM for a different monitor? The graphical display was unreadable. I was able to CNTL-ALT-F3 and login to a text based display and switch to "init 3" mode so that GDM and X and all the graphical tasks are not running. Now I would like to get graphical mode working with the new monitor. In case the broken monitor is repairable, is there configuration files I can backup to make falling back to the current configuration easier?
All the info is usually stored in the file /etc/X11/XF86Config. Copy it to a new name to save that configuration.
From an init 3 console, you can generate a new config using 'redhat-config-xfree86'.
