I have some problems to get the second monitor working on my Ubuntu 12.04.3 LTS. If I click on the detect button it does not work. Info about my system:

$xrandr -q
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1366 x 768, current 1368 x 768, maximum 1368 x 768
default connected 1368x768+0+0 0mm x 0mm
   1366x768        0.0  
   1368x768        0.0*

Before upgrading the system, xrand -q showed my much more resolution options and the other monitor.

I have tried to install intel-linux-graphics-installer but this version of ubuntu is not supported

Any help will be apreciated!!
