http://askubuntu.com – On my work machine the second monitor, connected to the DisplayPort (DP1). It keeps flickering into and out of existence, any help fixing it in this realm of existence appreciated. I'm only running onboard graphics, ie: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) Here's xrandr when ubuntu is NOT detecting it: xrandr -q Screen 0: minimum 320 x 200, current 1440 x 900, maximum 8192 x 8192 VGA1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 408mm x 255mm 1440x900 59.9*+ 75.0 1 (HowTos)
