Black desktop after starting a stopped container #1

Closed accetto closed 3 years ago

Today I started to experience black desktop after starting a stopped container. It happens under Windows 10 (updated today to Docker Desktop 3.0.0) and also under Linux (Ubuntu 20.04). Investigating the issue...

This problem can be fixed by tweeking the settings of the window manager (xfwm4).

Both of the following changes will help:

changing the value of vblank_mode from auto to xpresent or off
disabling the composition manager by changing the value of use_compositing from true to false

I've decided for the first option and set the vblank_mode to xpresent.
