I'm trying to install Ubuntu 12.04 Desktop on a Dell Precision T1600, however, I get a blank screen with only a blinking cursor in the top left hand corner (this is after the grey screen with the small Ubuntu logo at the bottom). If I remove the Nvidia Quadro 2000 card and plug a monitor into the built-in VGA port, then the installation works fine. Also, I've tried an Nvidia Quadro 2000D by PNY, but I get the same problem. Has anyone installed Ubuntu 12.04 Desktop on a Dell Precision workstation?
