This question might have been asked before but the solution posted there don't work for me. I have a laptop with the usual VGA output for a second monitor. On Windows I had no problem with connecting the second monitor but on Ubuntu 12.04 when I do it they start flickering like hell and I can't do anything (click, drag, open windows). I have installed the ATI driver (by following these instructions: Installing the AMD/ATI Catalyst drivers for 12.04 LTS) and everything goes well on the laptop's monitor.

I don't know if it is the driver or the system. I tried this solution and several xrandr changes but it doesn't work. My card is AMD Radeon HD 7600M series and the second monitor is a 19" Acer.

I can't believe that at this stage we have this kind of issues with something that should work without problems. Sticking to Ubuntu is a great challenge for me every day.

For those who my encounter this problem: you have to execute the commands after you connect the second monitor. Type them before, connect and when the flicker starts press ENTER. Remember:

xrandr --output VGA1 --auto --left-of LVDS1 --output VGA1 --auto --scale 1.0001x1.0001

or

xrandr --output VGA1 --auto --right-of LVDS1 --output VGA1 --auto --scale 1.0001x1.0001
  • God bless you! It works for me after, maybe, 6 hours! – Efog Jun 7 '16 at 17:20
