blank window in lxqt desktop when attach locally
cadem opened this issue · comments
I use a lxqt desktop in a docker.
I attach a session locally, but I got a blank window showed. I guess I missed something in my linux, but I don't know what is it.
The command is:
dbus-run-session xpra attach :100 --opengl=no
the log is as follow:
Warning: XDG_RUNTIME_DIR is not defined
and '/run/user/1000' does not exist

There are nowhere near enough details, please see https://github.com/Xpra-org/xpra/wiki/Reporting-Bugs
Try with a different window manager, Openbox doesn't do compositing.
It is very amazing, cairo.Context error is not related to window manager. I searched at the internet, found the solution:
sudo apt install python3-gi-cairo
After installing this package, I attach the session successfully.
Thanks!
Ah, that makes sense.
This problem only occurred here because of two unrelated issues:
- docker builds don't install all the recommended dependencies, it is likely that a normal installation would have brought in
python-cairo - running with
--opengl=nouses the fallback paint path, which requirespython-cairo
9c07f77 makes this a requires dependency for the client, a recommends one for the server (not needed unless the sync-xvfb option is used)
