Friends,
I just got a new Dell Optiplex 780 tower. I installed Ubuntu 10.4 LTS (32-bit) without any problems but I am unable to detect my second monitor. Going through Preferences/Monitors and clicking on "Detect monitors" does not find the second monitor.
The system has two video inputs, one integrated VGA-type (the one that works) and one in the PCI slot DVI-type.
The exact same setup (same monitors, same cables) worked beautifully on Karmic Koala.
Does anyone know how I can get 10.4 LTS work with dual heads?
Any help would be greatly appreciated.
Thanks
Ethan
