Title:
When returning from suspend, my external Apple monitor is not
detected, and nothing I do seem to enable it. Rebooting makes
everything work as it should. This was not a problem on 15.10.
Status in xorg package in Ubuntu:
New
Bug description:
After rebooting, xrandr --prop gives me:
DP2-1 connected primary 1920x1200+0+0 (normal left inverted right x axis y
axis) 495mm x 310mm

After suspend, it is simply listed as disconnected, trying various
xrandr commands doesn't make me able to connect it, adding a mode and
trying with "xrandr --output DP2-1 --mode 1920x1200" just gives me
