Comment 1 for bug 110543

modified /etc/X11/xorg.conf added 1920x1200 to 16 bit depth, changed default to 16 (from 24)
tried to run 'gdm' 'gdm restart' gdm-restart' 'gmd start' -- absolutely nothing happens, back to the command prompt.
startx flashes the display black and then prints something like the message above (X Windows System Version 7.2.0....) Fatal server error: no screens found XIO: fatal IO error 104 (Connection reset by peer) on X server ":0.0" after 0 requests (0 known processed) with 0 events remaining.
