Hello Rutger and all,

Our Xpra package seems to not be usable directly without installing
additional items:

Hello Ludo,

Does the :100 server show up when you do 'xpra list' after the command?

If so, can you try the following commands to see if it works:
$ guix environment --ad-hoc xpra --pure -- xpra attach :100
And then on a different terminal:
$ DISPLAY=:100 gui-program

Nope:

--8<---------------cut here---------------start------------->8---
$ guix environment --ad-hoc xpra --pure
[env]$ xpra start :100
Warning: Xorg binary not found, assuming the wrapper is needed!
ludo@ribbon ~/src/guix [env]$ Entering daemon mode; any further errors will be reported to:

[env]$ xpra list

No xpra sessions found
--8<---------------cut here---------------end--------------->8---

I believe the problem should be reproducible in a ‘--pure’ environment.
Perhaps the missing Python modules mentioned in the log are the root
cause?

Thanks,
Ludo’.

FWIW I get the same problem with the recent xpra 2.4.2 update.

Hi Ludo,

apologies for the delayed reaction, I've been quite busy. Oddly enough
the commands seem to work fine on GuixSD. Can you maybe tell me what
distro you're using?

I don't have access to a foreign distro at the moment, but I'll try to
look into it next weekend.

Do you have the 'xauth' command? If not, could you install that and see
if it makes a difference?

I’m using GuixSD.  :-)

If we use ‘-C’ instead of ‘--pure’, we should both get the same result:

--8<---------------cut here---------------start------------->8---
$ guix environment --ad-hoc xpra -C 
[env]# xpra start :100

[env]# 
[env]# xpra list

--8<---------------cut here---------------end--------------->8---

Same for you?

Thanks for your feedback,

[-- Attachment #1: Type: text/plain, Size: 2161 bytes --]

So it should actually work in the container if you run the command xpra
upgrade, like so:

container$ xpra start :100 # wait a few seconds for it to start
container$ xpra upgrade :100
container$ xpra list

Just starting it in a container isn't terribly useful though since that
way you can't attach to it. If you run
guix environment --ad-hoc xpra -C --share=/tmp/.X11-unix
--share=/home/$USER/.xpra

and then start the server with the above commands you should be
able to attach to it outside of the container, like:
$ xpra attach :100
$ DISPLAY=:100 gui-program # on a different terminal

Does this work for you too?

I'm not sure why the 'xpra upgrade' command seems to be required in a
container. I have no idea how to fix that.

This command seems to work for me now (with xpra 4.2.1):

--8<---------------cut here---------------start------------->8---
$ guix environment --pure --ad-hoc xpra -- xpra start :100
Warning: using '/run/user/1001' as XDG_RUNTIME_DIR
Entering daemon mode; any further errors will be reported to:
  /run/user/1001/xpra/:100.log
$ guix environment --pure --ad-hoc xpra -- xpra list
Warning: using '/run/user/1001' as XDG_RUNTIME_DIR
Found the following xpra sessions:
/home/sarah/.xpra:
	LIVE session at :100
/run/user/1001/xpra:
	LIVE session at :100
--8<---------------cut here---------------end--------------->8---

And xpra now retains a reference to dbus, which has dbus_launch.

Can you still reproduce this?
