Public bug reported: the excellent instant messenger psi-plus, uses the window class "psi". Thus, after launch it will be displayed as an extra icon in both unity and gnome-shell.
This can be easily fixed by adding the following entry to the psi- plus.desktop file: StartupWMClass=psi regards, Bernhard LSB Version: core-2.0-amd64:core-2.0-noarch:core-3.0-amd64:core-3.0-noarch:core-3.1-amd64:core-3.1-noarch:core-3.2-amd64:core-3.2-noarch:core-4.0-amd64:core-4.0-noarch psi-plus: Installed: 0.15~svn3910-1ubuntu1 Candidate: 0.15~svn3910-1ubuntu1 Version table: *** 0.15~svn3910-1ubuntu1 0 500 http://at.archive.ubuntu.com/ubuntu/ oneiric/universe amd64 Packages 100 /var/lib/dpkg/status ** Affects: psi-plus (Ubuntu) Importance: Undecided Status: New ** Tags: oneiric -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/894585 Title: psi-plus.desktop misses entry StartupWMClass To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/psi-plus/+bug/894585/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
