I'm trying to get ubuntu working w/ 3 monitors. I have been given 2 video cards
lspci | grep VGA
20:01:00.0 VGA compatible controller: ATI Technologies Inc RV620 LE [Radeon HD 3450]
25:05:00.0 VGA compatible controller: nVidia Corporation NV44A [GeForce 6200] (rev a1)
I have had it working w/ two monitors plugged into the ATI correctly. and the nVidia monitor blank. Now I have the nVidia monitor working and one monitor from the ATI working, but I can't seem to get the last monitor to show anything. It does show the boot screen and works up until the point you are presented w/ the login screen for ubuntu, then it disappears and the nVidia monitor turns on. Might I have something wrong w/ my xorg.conf or do I need to do something more to get this to work?
Currently I'm seeing this error in my Xorg.0.log file, but I'm not sure where to go from here:
[ 24.746] (EE) RADEON(2): reusing fd for second head
