Hello,
I am trying to configure two1920x1200 screens with a Dell E7440 and E-Port Simple II docking station. One of the monitors is connected to DVI output, another monitor is connected to the DisplayPort output. The laptop runs Linux, which is probably part of a problem, but still... Here's the problem:
I do not see two screens. Instead, xrandr outputs a 'virtual' screen 3840x1200 that is a combination of my two screens. But I want two independent screens! Any idea how to have them?
~$ xrandr
Screen 0: minimum 320 x 200, current 3840 x 1200, maximum 8192 x 8192
