DisplayLink Forum - View Single Post - Ubuntu 22.04 with DL 5.6.1 is laggy if no WGA screen plugged

Hello the Community,

I recently updated my computer (not a laptop) to Ubuntu 22.04 (installation from scratch, new hdd)
I installed the DIsplay Link Driver version 5.6.1
I have 3 Screens connected to the Display Link.

The 3 screens are laggy if the Display Link Device is used alone (no other screen plugged to the computer)

The 3 screens work fine only if I connect a WGA screen at computer startup. Then I can unplug this VGA screen, the other screens continue to work

Previously, I was using the same computer with an Ubuntu version 20.04 and Display Link version 5.5 without any issue.

Any way to solve this? thanks

echo "$XDG_SESSION_TYPE"
returns wayland
