Moss,

Have you made any major changes to your cygwin X server settings? I tried this with a fresh install of the cygwin Xserver suite, first thing i did, but was unable to get it to work. 

I assume you are using Docker Desktop? Do you have it integrated with WSL? 

Thanks for the quick reply! This will be my last for the night. Don't want to flood.


Chris

I can run a cygwin X app in a cygwin console and get an X window, and I can run a wslg app in a wsl bash instance and get an X window, each on their respective servers. But when I set the env DISPLAY in one to the X of the other, it breaks.

The cygwin X server is vastly superior to the wslg one, at least insofar as integration with the windows 10 chrome; cygwin X windows no matter the library will snap like a regular windows window will. Anything coming out of wslg, at least when it comes to gtk3 (emacs-git) and QT4 (qutebrowser), have no native window decorations and don't snap. I've also been unable to find a way to run a docker container as a single X root window (ie to run a DE inside of a container) but I bet if I could connect to the cygwin X server that'd be fairly straightforward.

At least thats how i landed on this topic, but it seems to me being able to run a docker container and have it hook into a cygwin X server that's already running would be a good feature generally. Especially if it would enable me to disable WSL again.
