Hi, I am on 21.10 with intel driver and latest displaylink from their website. Everything used to work decently until a couple of day ago when I started seeing the external monitor very slow. I was on 21.04 and after an update it has started being slow.
1. It is slower when more things change on the screen, only the mouse works slow a full screen rendering is unusably slow. 2. on the login screen the screen works very well, as I was used to. 3. Audio work fine, rendering is very slow About my pc 1. Linux vin 5.13.0-20-generic #20-Ubuntu SMP Fri Oct 15 14:21:35 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux 2. Driver from display link displaylink-driver-5.4.1-55.174 3. Tried X11 and Wayland from GDM with Gnome I tried to troubleshoot as described here https://wiki.archlinux.org/title/DisplayLink and setting LIBGL_DRI3_DISABLE=true as said here but it does not change Any hint is appreciated!
