Title:
Screen resolution on external monitor won't go above 2560 x 1080
Status in linux package in Ubuntu:
Confirmed
Status in xorg-server package in Ubuntu:
New
Bug description:
I have an external monitor capable of 3440 x 1440. I am using a
Thinkpad T480s. Up until about 2 weeks ago, I could set the resolution
of the monitor to 3440 x 1440 just fine. Now when I try, the screen
goes black and I have to revert to a lower resolution. The highest it
will go now is 2560 x 1080. Lower resolutions work fine as well.
