[Desktop-packages] [Bug 1878951] Re: [nvidia] Hotplugging HDMI monitor is ignored, needs to be manually re-enabled

2020-08-02 Thread Frank Blah 
Workaround for me was to use external USB-C to HDMI adapter and plug the
USB-C to the computer.

  Steps to reproduce:
  1. Successfully connect AOC u2879vf external display by attaching HDMI cable
  2. Remove the cable, output switches to the built-in display and external 
display goes black
  3. Reconnect the HDMI cable again

  What is expected:
  The external screen should display the image (as in step 1)

  What happened instead:
  The system thinks the display is connected (see the xrandr output), but the 
external display is still black (no signal). The clumsy workaround is to use 
Super+P to switch to "built-in display only" and then back to "joint". After 
that, the external monitor comes back.
