Since I reported this, the Ubuntu Appindicators extension has turned up. If I enable that, and not TopIcons Plus, and log in using the Ubuntu desktop session rather than the Gnome one, the QT tray icons now show up. This appears to apply both in Xorg and Wayland. This is clearly The Future, given the planned demise of the legacy system tray, so I'm OK for this bug to be closed.
FWIW I had tried the original extension from which Ubuntu Appindicators is forked, without success. I don't know why this one's working now, but I'll take it. Actually on one system it seems only to work in the Ubuntu session, in the other it works in the Gnome session too. I'm guessing that's something that'll settle down as there seems no reason to that. On a hidpi screen (both systems) the icon is not scaled accordingly, so it shows up but it's tiny, but that's for another bug report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1712366 Title: tray icon does not appear on gnome To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/owncloud-client/+bug/1712366/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
