Bug Description
Upstream bug report: https:/
Imgur post that explains problem: http://
When my ASUS VW193 external monitor is connected to the VGA port of my laptop (AMD Radeon 7470m) internal laptop monitor stops working. Using the Unity Control Center I'm able to set laptop monitor as primary which disables external monitor (and vice-versa). Tried manual switch to mainline Linux 4.5 kernel, same thing. Tested on 14.04, 15.10, 16.04, 17.04 and 17.10 (develop branch) with same results.
However, if I plug the Asus monitor into the laptop via VGA, plug my Vox TV into the laptop via HDMI, and set the resolution to 1280x720, it displays fine on both the monitor and TV.
Also, the internal monitor and just HDMI together show properly.
However, if I adjust to 1080i, the above working dual screen configurations show a graphical glitch:
