How to get gamescope working on Zorin OS 18

i use x11 and stil not working any help?

It is really difficult to install this program on Zorin 18 because there are many missing dependencies. Did you try to build it from source?

Maybe this github thread can help? But I'm not familar with this topic.

Gamescope only works on Wayland by default, or on X11 if you have the right compositing setup. On plain X11 without compositing, it might not start at all. You could try switching to a Wayland session or installing the required packages for X11.
