Subject: bug#36924: Mesa/GDM/XFCE
Date: Thu, 12 Sep 2019 11:54:30 +0200

Hello,

now it is my turn to experience a problem in this area. I newly installed a
machine with the graphical installer of Guix 1.0.1 (where I could use xfce
without problem), then I issued a "guix pull" and a "guix system reconfigure".

Now logging into XFCE poses problems, which I can reproduce as follows
(after removing /var/lib/gdm, $HOME/{.config,.cache,.local} once):
- When I remove $HOME/.config/xfce4/xfconf/xfce-perchannel-xml/xfwm4.xml
  I can log into XFCE once.
- The second time, various problems may occur: The terminal, which was open
  before opens, but does not receive focus so I cannot type, and the windows
  decorations for closing it are absent; or the xfce panel is absent.
- Then I remove $HOME/.config/xfce4/xfconf/xfce-perchannel-xml/xfwm4.xml
  again, and can log in once more.
And so on.

The following lines in $HOME/.cache/gdm/session.log appear when there is
a problem:

Sorry for the German, but you also have the translation:
"Zusicherung ... nicht erfüllt" = "assertion ... failed"
"auf dem Nachrichten-dbus verloren" = "lost on the message dbus"
