linux-howto

http://ubuntuforums.org – Hi, I'm running into an issue when trying to set up my dual monitors with 12.04. I'm using Unity with Lightdm, and my second monitor (with desired 1920x1080 resolution) is only 640X480! Also, the second monitor is completely white with a black x for a cursor. Can anyone tell me why this is happening? Output for xrandr -q: Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 1920 x 1920 DFP1 disconnected (normal left inverted right x axis y axis) DFP2 disconnected (normal left inverted right x axis y axis) DFP3 disconnected (normal left inverted right x axis y axis) DFP4 disc (Hardware)

Hi All,

While reading another thread I ran the xrandr command and got the following output. Why are DVI-1-0 and DVI-1-1 disconnected and my system is running on DVI-I-2 & 3?
