Date: Thu, 27 Apr 2017 22:22:05 +0000

At the moment trying to login through SLIM (same with SDDM) into LXDE
you get the message "Failed to execute login command" for
about 2 seconds, then the X session terminates and your are
back at SLIM.

Effectively through the login managers we have, LXDE is not
usable at the moment. I haven't tested using just "startx".

I open this bug so that it can be referenced and is visible. To me
it is known since I've sent in the meta package for LXDE.

Does ~/.xsession-errors contain any hint?  That is, try to log in and
fail, then go to tty1 with ctrl-alt-f1, log in, and run
“cat ~/.xsession-errors”.

Thanks,

Hi,

I would've appended the file if it existed. But $home/.xsession-error
doesn't exist here.

Indeed, not sure why.

I was able to reproduce the problem in a VM with the attached config.
It boils down to this:

--8<---------------cut here---------------start------------->8---
$ /gnu/store/9fdxlzwbsfzhncwznlx2lrp8rdq61f7v-lxde-common-0.99.2/bin/startlxde 
cp: cannot stat '/etc/xdg/openbox/LXDE/rc.xml': No such file or directory
/gnu/store/9fdxlzwbsfzhncwznlx2lrp8rdq61f7v-lxde-common-0.99.2/bin/startlxde: line 47: /gnu/store/9fdxlzwbsfzhncwznlx2lrp8rdq61f7v-lxde-common-0.99.2/bin/lxsession: No such file or directory
--8<---------------cut here---------------end--------------->8---

The ‘cp’ error seems harmless but the other one is obviously
problematic.

Could you check what’s wrong with ‘startlxde’?

Thanks!

Ludo’.

Thanks.

Yes, I will do so though if someone else feels like picking
this bug up, feel free to do so as it could take some time
for me to get back to this.

Please email bug-guix if there are other problems with LXDE.

Thanks,
