Kind of an Ubuntu noob here. I'm trying to run 2 external monitors along with my laptop monitor on Ubuntu 11.04. I have a Lenovo T520 with the following graphics:
VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
I have turned on all three displays under "Monitors", but only the two external screens are displaying anything. The laptop screen will not display.
Running xrandr gives the following (when both externals are hooked up):
Screen 0: minimum 320 x 200, current 3600 x 1080, maximum 8192 x 8192

HDMI2 disconnected (normal left inverted right x axis y axis)

As you can see, the LVDS1 display is "connected" but no resolution is selected, even though a resolution is selected under the "Monitors" window. Am I doing something wrong? Or is this even possible? Sorry if this is a stupid question.
