One possible reason it crashes is the python2-xlib is far outdated. The

package was added in patch db62afa55ad443cc50bcafe64eb3ba239eae9c11

(2015) and has been version 0.14 ever since. The website says it has

been migrated to github, which says the most recent stable release is

0.25. It looks like there is a similar issue (though not identical) htt

ps://github.com/python-xlib/python-xlib/issues/53 which was fixed.

I will see if updating python2-xlib fixes this, and if so I will send a

patch.

Any objections?

Jesse,

Jesse Gibbons ???

On the contrary. That's exactly what we want!

Just FYI this is still broken.

I don't understand how you are reproducing this backtrace:

$ guix environment key-mon --ad-hoc key-mon -- key-mon

Error: Missing xlib, run sudo apt-get install python-xlib

$ sudo apt-get install python-xlib

sudo: apt-get: command not found

It was worth a try.

How are you launching key-mon? Is this because I'm not using X?

Kind regards,

I get the same error when i launch it as `key-mon` from the console,

after I installed the package.

I tried with `--pure` now and I get your error:

```

Lol.

Some things discovered on IRC:

"works for me with [patch below] and by running: $ ./pre-inst-env guix

environment --ad-hoc key-mon gdk-pixbuf+svg --pure -- $(which bash) -c

'DISPLAY=:0 key-mon'"

"figuring out where to propagate gdk-pixbuf+svg remains to be found"

```patch

Are there any updates on this, did anyone get it to work? I just tried with the same issue on opening display for me too.

I'm seeing the same thing in trying to package autokey, but with the error displayed in a graphical window on the X server (and yet it says it doesn't know the protocol). This also uses python-xlib, gtk, etc.

Thanks,

John

Of course immediatly after I found a workaround, for key-mon and my case: allow all to connect to X with `xhost +`. Certainly not the ideal thing to do as it disables authentication with X, but show the problem.

Does anyone know the proper way to deal with this for these python packages?
