Hi all,
First mail, so while I'm fairly sure it's on topic please forgive me if it
isn't.
Has anyone tried to get a docker container with an X app in it to connect to
the cygwin x server?
When I run startxwin after starting the wslg container the cygwin Xserver comes
in at address (word?) :1 rather than :0, so the two servers can recognize each
other (at least to some degree). 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.
This isn't just a stupid ask for a redundant use-case, either. 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.
I'll be the first to admit I don't know too much about X so is what I'm asking
even possible? (I do mainly use linux, but normally X is one of those things
that i dont fiddle with much)
UItimately/mostly I'm just fed up of being stuck in Windows windowland at work
and not having emacs-git*. 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.
(*As an aside: while I have gotten it to compile, and it runs in the console,
so many tests break that I'm afraid to even try compiling it for gtk3; so a
docker container of debian stable seemed a logical next step and i
half-expected it to just work, to be honest, given how seamless the rest of my
cygwin experience has been recently, and I would put money on these two issues
being on docker/docker-desktop/wsl, given how poor wslg's integration is
despite being a microsoft project)
If it's of any help in understanding this, in wsl I set DISPLAY=:0
and can start X apps that connect to the Cygwin X server. I wonder
if there are issues trying to run two X servers at the same time ...
