Ater a login with GDM and GNOME desktop I immediately get an error dialog box:
HPLIP Status Service
No system tray detected on this system.
Unable to start, exiting.
TopIconsPlus shows an error:
This extension is incompatible with the current version of GNOME.
Additional info. The solution from bug #23795 doesn't work anymore because the developement of gnome-shell-extension-topicons https://github.com/phocean/TopIcons-plus stopped and the successor is gnome-shell-extension-appindicator https://github.com/ubuntu/gnome-shell-extension-appindicator. It should be replaced in cauldron/Mageia 9.
A manual test by installing the new extension via https://extensions.gnome.org/extension/615/appindicator-support/ under cauldron worked and solved the above error. This extension should be packed for cauldron/Mageia 9.
To make it more clear: gnome-shell-extension-topicons is not compatible with new gnome shell versions like we use in cauldron.
Thanks to both of you for the report & comments.
Assigning to the Gnome people; this will have to be reflected in future Gnome installs.
Should be fixed with gnome-shell-extension-appindicator-41-1.mga9. Imported it based on .spec from Fedora.
$ urpmq --obsoletes gnome-shell-extension-appindicator
After installation of gnome-shell-extension-appindicator-41-1.mga9 and a necessary restart (i didn't test if log out/log in is enough), the extension is available under the extension menu. Enabling it removes the error from the initial post. Problem solved.
Can you check what's the output of the following cmd?
$ rpm -qa *appindicator*
I think appindicator lib or gir pkg is also required. ATM they're not pulled automatic with the pkg.
[gnome@localhost ~]$ rpm -qa *appindicator*
It's a Virtualbox Gnome installation updated from Mageia 8 to cauldron.
OK, I added libappindicator-gtk3 requires to gnome-shell-extension-appindicator-41-2.mga9.
Closing as FIXED. Feel free to reopen if needed.
