According to https://community.ubuntu.com/t/testing-unity-session- in-18-04/987/257,
LO is not detecting XDG_CURRENT_DESKTOP properly. Editing exec line in .desktop seems to solve the problem. Exec=env XDG_CURRENT_DESKTOP=Unity libreoffice --writer %U Since it works on Ubuntu 16.04, I guess something went wrong in detecting Unity. Note Unity changed XDG_CURRENT_DESKTOP from Unity to Unity:Unity7:ubuntu after 16.10. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1589215 Title: 'Unknown Application Name' menu item in Indicator Applet Appmenu when LibreOffice is running To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1589215/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
