You could try to add it manually (information taken from http://wiki.debian.org/XStrikeForce/HowToRandR12 Section III.5): xrandr --newmode "1280x1024_75" 138.54 1280 1368 1504 1728 1024 1025 1028 1069 -HSync +Vsync and then do xrandr --output VGA-1 --mode 1280x1024_75 This could work, if the above modeline was actually correct and not just an example. I don’t know wether it should work, as I don’t have any screen of that size at the moment to test with. You might also try to play with +HSync and -Vsync (or any combination of the two) if you experience short blackouts (my Samsung SyncMaster T240 doesn’t like +Hsync -Vsync but is totally happy with +Hsynv +Vsync…). If it does work, you can write a small script with these two commands to set up the display resolution automatically at startup and add this script to your DE’s autostart configuration.
