Description agilob 2015-12-23 21:02:00 UTC

After an update (in Arch) 3-5 days ago applications can't detect system tray. KDE-based applications (kdeconnectm nm-applet) still work in system tray, but others like qTox, skype, clementine can't detect it anymore.

Eg. log from clementine:
__logging_message__21:59:05.293 WARN  unknown                          QSystemTrayIcon::setVisible: No Icon set

All entries that were in system tray config disappeared, see attached.

Reproducible: Always




I use Arch linux which is updated daily, so all packages have the same version as in https://www.archlinux.org/packages/

The bug was also reported to https://bugs.archlinux.org/task/47486

Note that the package linked in the downstream report has the patch from https://bugs.kde.org/show_bug.cgi?id=355463#c9 applied, and doesn't seem to fix the issue.

Do you have sni-qt installed?
Is xembedsniproxy running?

Comment 4 agilob 2015-12-24 07:54:20 UTC

Yes.

I think so (but it wasn't 3 days ago when I reported it to arch bugs).

 ~  ps auxf | grep xembedsniproxy

I found the problem. After the upgrade some background services were disabled (system settings->startup and shutdown -> background services). Bluetooth, device manager, status notifier manager were disabled. Enabling SNM fixed my issue...
