Additional monitors are forced to be OFF after updates
Hi All!
Faced new totally no-go problem:
Setup:
* Dell XPS 13 '18, Core i7
* Ubuntu 20.04
* Xorg
* DELL 3100
* 3x Dell 24" 1920x1200 monitors
0. Everything is still working superfine under Windows. This is not a hardware problem.
1. Everything was working nice for me from the release of Ubuntu 20.04
2. Last time everything worked for me in Ubunto 20.04 was this Dec 21 2020.
3. After couple of days of not touching the setup, today (Dec 24) - whatever I do - it is not possible to turn ON any additional monitors.
Monitors are detected well (I dynamically see when I plugin/plugoff some of those), but they are in the OFF state! And when I in display settings ON all of them (or only some) and press "Apply" button in the display configuration... whatever I juste wait or I press "Keep Changes" or "Revert Settings" - I fall back to a state when ALL additional monitors are just OFF in settings, and I am again is only with laptop screen.
So - not possible to ON any additional monitor, when things worked fine all these monthes before.
Could you please advise me?
