We should probably open a new bug about those problems in Wayland
sessions. If you wanted to just focus on Wayland then we can close this
bug about Xorg crashes. If you like? Or we can keep two bugs open, I
don't mind.

Title:
  [DisplayLink] Xorg crashes and return to login screen

Status in evdi package in Ubuntu:
  Incomplete
Status in xorg-server package in Ubuntu:
  Incomplete

Bug description:
  The bug is that all at a sudden gnome reset to login screen. When i
  log again, the only "sound output" allowed is simulation, my devices
  are not displayed.

  I'm using 
  - Ubuntu 20.04 (I upgraded from 18 some months ago, I don't think this bug 
was present at that moment but i used less my ubuntu station). 
  - Portable PC

  The bug happen
  - When I use my PC with screen pluged directly : some times
  - When I use my docking station with 144Hz display in DVI 
(https://i-tec.pro/fr/produkt/u3hdmidvidock-4/) : quite frequently
  - When à Use my docking station and watch some full screen video : very 
frequently

  It seems to be linked to displayLink use, but not only because it
  happen too when i don't use the docking station. It seems to be
  frequently when i "Stress" the screen.
