Xephyr as a different user

Is it possible to open a gnome session in xephyr as user A while being logged in a gnome-shell session as user B?

When I tried to run `startx` after doing `su user_A`, it gave:

xauth: timeout in locking authority file /run/user/1000/.mutter-Xwaylandauth.RWEXY0

I can only assume you are not posting your full/actual commands: startx will not work from within a running X session. Xephyr will, but you said you just ran "startx".

I "su"ed into user B, opened a xephyr window, set the display env var to that window and then ran "startx"

You didn’t read, startx will not work with xephyr, because startx will try to launch Xorg in that display that is already used by xephyr...

Instead you should just launch your WM in that display, doing the other things like xinitrc.

Is there a way to launch a full-fledged GNOME session?

Only one way to know, try and launch the session with that display, it should work...

gnome-session says that WM doesn't support the session

Could it be that it’s trying to launch in wayland? Otherwise that’s all I can think of...gnome is a...special cookie

I'm using Wayland by default. Can that be an issue?

As far as I know, yes, since xephyr is X11 methinks.

You probably still want to ensure the systemd scripts in /etc/X11/xinit/xinitrc.d get sourced.

However, mutter may also not like the software GL environment and deem it insufficient (but idk that)
