Public bug reported:
Hello,
after upgrading to 20.10 from 20.04LTS I have the following issue:
I have a laptop in docker with 3 external screens connected (1 VGA, 2 HDMIs).
If I close the laptop lid all external screens work but when I start citrix
workspace my screens start to flicker then xorg restarts and citrix either
starts on an external screen or on the closed laptop screen. This was working
without errors on 20.04 release.
Could you pls check?
Thanks, Zoltan
