Ok, one step closer to solving the mystery: it seems that sflphone does not support Unity's new indicator icons. I had sflphone configured to hide the main window on startup, and, well... it did. But since I couldn't see the tray icon (or any other indication for that matter), I couldn't use it.
By turning off hide at startup, I can use it with Unity. Nevertheless, it would be better to have it in the tray as I'm accustomed to doing. Everything works as expected on "Ubuntu Classic" mode, i.e., using regular Gnome. ** Summary changed: - Sflphone window disappears immediately + Sflphone does not support Unity-style tray icon -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776656 Title: Sflphone does not support Unity-style tray icon -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
