I just purchased a Dell U2711 monitor (max resolution 2560 x 1440) to hook up to my work desktop (Dell Optiplex 780 SFF with integrated Intel GMA 4500 graphics and with onboard DisplayPort and VGA connectors).

Under Windows 7, everything works as hoped--extended desktop with new monitor on DP (full 2560x1440), old monitor on VGA (rotated to 900x1440).

Under Ubuntu (10.04 and 12.10) with only the new monitor hooked up, the DisplayPort gets no signal. VGA max resolution on the list is 2048x1152. Saw in another thread here that someone else just had to reboot to get DP working--no such luck for me.

Any ideas?
