Hi
1)
$ lsb_release -rd
Description: Ubuntu 20.04.2 LTS
Release: 20.04
2)
$ apt-cache policy xorg

3) What you expected to happen
I have a "HP EliteBook 840 G5 (3RF31LT#ABM)" laptop with ubuntu 20.04
Also I have a Dell dock model k17a connected with 2 monitors.
The physical display is the following:
laptop(landscape) | monitor 1 (landscape) | monitor 2 (portrait right)
When I connect the USB-C plug, I expect nothing special but having 2
more display
4) What happened instead
When I connect the USB-C plug, the whole UX gets super slow
Xorg and gnome-shell are the top 2 cpu-consuming process and both inside the
same CPU2
