 Posted: Sat Oct 01, 2022 9:47 pm Post subject: KDE system tray icons missing |
 |
|
When i launch kmix from a konsole during a KDE session, i get the following error message after a waiting time of a few minutes:
| Code: | | kf.dbusaddons: Couldn't register name 'org.kde.kmix' with DBUS - another process owns it already! |
and kmix is not launched. However, this is just one symptom among many that i think are related in that there is a "lack of communication" with system tray applications. For instance, switching keyboard layout via the keyboard shortcut that i defined (Alt+Space) does work, but the keyboard layout widget does not change its language indication. In fact, sometimes the keyboard widget does not display at all, along with other missing system tray icons. Similarly, some applications that normally place an icon in the system tray (such as an audio player, e.g. deadbeef) fail to do so.
My situation is very similar to the one described here: https://forum.manjaro.org/t/applications-icon-missing-in-system-tray/109433 . I tried their suggestions:
- I deleted all KDE-, plasma- and Qt-related files and directories in $HOME/.cache
- rm $HOME/.config/Trolltech.conf
- rm -r .dbus/ and restarted dbus
- rm $HOME/.config/plasma-org.kde.plasma.desktop-appletsrc
- rm $HOME/.config/kwinrc
- kbuildsycoca5 --noincremental
- Created a new user
Unfortunately, none of the above worked for me.
This is a rather debilitating situation as the working environment is quite severely degraded. Suggestions are appreciated! |

What is the output of
| Code: |
echo $XDG_RUNTIME_DIR
ps -ef | grep -i kmix | awk '{ print $1 }'

Are you launching it as root or as your ordinary user?

Funny that you asked because when i type "kmix" in the terminal, i get the following message twice:
| Code: | QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-<my_username>'
|
and then it hangs for a few minutes before reporting the DBUS error message that i mentioned above. So i guess the answer to your question is not surprising:
| Code: | % echo $XDG_RUNTIME_DIR
XDG_RUNTIME_DIR: Undefined variable.
|
I had looked into the origin of this message before, but at the time it seemed innocuous to me, since it seemed to be finding its own solution (creating the directory in /tmp). Now that you mentioned it i looked it up again, and the references that i found are all from systemd users, where XDG_RUNTIME_DIR should be set by pam_systemd using logind but was not. However, i use OpenRC and i am not sure how this information translates to this case (elogind?)

<my_username>
<my_username>
<my_username>
|
where <my_username> is my username (not root). Also, in case it helps any:
| Code: | % ps x | grep -i kmix
8824 pts/9 S+ 0:00 grep --color=auto kmix
28728 ? S 0:00 /usr/bin/kmixctrl --restore
29281 ? Sl 0:00 /usr/bin/kmix --keepvisibility
% kill -QUIT 28728 29281
% ps x | grep -i kmix
13325 pts/9 S+ 0:00 grep --color=auto -i kmix
% kmix
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-<my_username>'
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-<my_username>'
percent 5 -> divisor 20

This is the first time i see this "percent 5 -> divisor 20" line. And now kmix just hangs there. I CTRL-C'd it after 10 minutes or so, and "ps x | grep kmix" returned empty, so nothing was launched.

As my ordinary user. The entire KDE session is also launched from my ordinary user, of course. |

Do you have a
directory?
For some reason your kde is not exporting XDG_RUNTIME_DIR.
This is done via /etc/pam.d/elogind-user
Is elogind running?
Try
| Code: |
cat /etc/pam.d/elogind-user
|
Are you using systemd or openrc
What happens if in ~/.bashrc
you include
| Code: |
export XDG_RUNTIME_DIR="/run/user/$UID"
|
?

You were spot on about elogind, something went wrong with it for some reason:
| Code: | # rc-service elogind status
* status: stopped
# rc-service elogind start
* Starting elogind ...
* start-stop-daemon: /lib64/elogind/elogind is already running [ !! ]
* ERROR: elogind failed to start
# rc-service elogind stop
* WARNING: elogind is already stopped
# rc-service elogind zap
* Manually resetting elogind to stopped state
(orb:~) # /etc/init.d/elogind status
* status: stopped
(orb:~) # /etc/init.d/elogind start
* Starting elogind ...
* start-stop-daemon: /lib64/elogind/elogind is already running [ !! ]
* ERROR: elogind failed to start
# ps ax | grep elogind
3384 ? S 0:00 elogind-daemon
# kill -QUIT 3384
# ps ax | grep elogind
# rc-service elogind start
* Starting elogind ... [ ok ]
# rc-service elogind status
* status: started
|
At that point i logged off the KDE session to SDDM, and logged back in again. Now the problems you mentioned are fixed:
| Code: | % echo $XDG_RUNTIME_DIR
/run/user/1000
% ls /run/user/
1000 |
However, my original problem is still not fixed. kmix does not hang forever and does not produce the "XDG_RUNTIME_DIR not set" anymore, but after a couple of minutes of waiting it issues the same error message:
| Code: | % kmix
kf.dbusaddons: Couldn't register name 'org.kde.kmix' with DBUS - another process owns it already!
