Bug#990733: xfwm4: Resolution drops from 3840x2160 to 2560x1440 on power save
Package: xfwm4
Version: 4.16.1-1
Severity: normal
Dear Maintainer,
Occasionally - maybe once a week - after re-waking a sleeping monitor, the screen resolution changes as per subject. Settings, Display then shows a maximum available resolution of 2560x1440. Logging out and in keeps the lower resolution, but Settings, Display now allows it to be changed back to 2840x2160.
Monitor is Dell P2715Q; graphics card is NVIDIA Corporation GP107GL [Quadro P620] (rev a1).
