lightdm / cinnamon XApp Status applet issue

[Marcus Haarmann]

Hi all,

not sure where to report the issue, so I will try here. Maybe somebody can point me where to address this.

I ran into an issue in the following scenario (was able to reproduce in a clean environment):
Base is a fresh Ubuntu 24.04.3 installation
Added cinnamon-desktop-environment and lightdm

When logging into cinnamon (which works), the XappStatus applet is not showing the non-cinnamon apps
(like nm-applet).
First, in xsession.errors there was an output of several scripts in /etc/X11, which stated that has_option is not defined.
     /etc/X11/Xsession.d/30x11-common_xresources: Zeile 16: has_option: command not found
I already found a bug report for this (a directory in /usr/sbin/lightdm-session is wrong in this environment).

  *
Solution sudo ln -s /etc/X11/xinit /etc/X11/xinit/xinitrc.d

(or somebody patches the script /usr/sbin/lightdm-session (line 86), but this would be a temporary fix only if next version of the package replaces the file)
The has_option errors vanished, but had no effect on the XappStatus applet

I switched to gdm3

  *
Effect was that the XappStatus Applet was still not working

removed lightdm

  *
Effect was that XappStatus Applet was working immediately after login

I then checked which packages were removed along with lightdm and added them back one by one.

  *
Found that indicator-application package was the package which prevents XappStatus applet to work correctly.
  *
What I saw was that as an effect, the daemon xapp-sn-watcher is not running

New try with lightdm installed and afterwards indicator-application removed

  *
got a working system

So for me it is working now, but maybe somebody else is running into the same issue.
So removing the indicator-application package and setting the symlink as stated above does help.

Maybe somebody can fix this in lightdm/cinnamon integration.

Best,

Marcus Haarmann
