DisplayLink Forum - View Single Post - DL 5.6 Ubuntu 22.04 - Extreme Machine lag when using external display

mTUX · 08-21-2022, 05:13 PM

Usually I use the same (I mean literally) system (currently Ubuntu 22.04) on every machine I use, and today the first time I attempted to use on an AMD machine (Steam Deck). I also have this severe performance hit (1-2 FPS) on Xorg OpenGL, but not with Wayland. Unfortunately KDE Plasma is just not Wayland-ready yet, so I'm stuck with Xorg right now.

The strange thing is the problem only occur if I set my primary monitor to the one which uses DisplayLink. As soon as I change the primary monitor back to the internal everything works fine.
