Public bug reported:
When I have my screen resolution set to 1920 x 1080 (16:9), and I use my
KVM switch to change to my laptop, if I am 'away' for more than about 10
minutes, when I click back to my Ubuntu workstation, the display is set
to some very low, barely recognizable, resolution. As a work-around, I
can click on System Settings and then click on Displays, and the screen
immediate flickers and then resets back to 1920 x 1080, without the need
for me to do anything else. This is most annoying, and it was not seen
in previous versions of Ubuntu.
All I would like is the ability to lock the screen resolution so it
doesn't change on me automatically when I am using my KVM and am 'away'
for extended periods.
