Title:
Only one monitor working at the time (xorg-amdgpu)
Status in xorg package in Ubuntu:
New
Bug description:
When external monitor is connected to VGA port (AMD Radeon 7470m) internal
laptop monitor stops working. I'm able to set laptop monitor as primary which
disables external monitor (and vice-versa)
I was using fglrx without problems however after fglrx support dropped in
recent Ubuntu update I was forced to return to xorg driver. Tried manual switch
to mainline Linux 4.5 kernel, same thing. Tested on 14.04, 15.10, 16.04 with
same results.
