It seems like our desktop customiser does not work when using kde5 plasma. After creating an application group and defining a menu structure for that group, and activating with /opt/thinlinc/bin/tl-desktop-activate.sh, once logged in with KDE nothing but the standard menu structure is shown. With Xfce everything seems to work as expected. The file that gets generated for a customised menu structure is named applications.menu and is located in ~/.config/menus/applications.menu, according to the freedesktop.org standard. Many desktop environments seems to have their own name for this file, for example this is what we create per default -rw-rw-r--. 1 cendio cendio 816 9 mar 09.03 applications.menu lrwxrwxrwx. 1 cendio cendio 44 9 mar 09.03 kde4-applications.menu -> /home/cendio/.config/menus/applications.menu lrwxrwxrwx. 1 cendio cendio 44 9 mar 09.03 kde-applications.menu -> /home/cendio/.config/menus/applications.menu lrwxrwxrwx. 1 cendio cendio 44 9 mar 09.03 lxde-applications.menu -> /home/cendio/.config/menus/applications.menu lrwxrwxrwx. 1 cendio cendio 44 9 mar 09.03 mate-applications.menu -> /home/cendio/.config/menus/applications.menu lrwxrwxrwx. 1 cendio cendio 44 9 mar 09.03 xfce-applications.menu -> /home/cendio/.config/menus/applications.menu I verified what the system has installed for us in /etc/xdg/menus/, and there we have an kf5-applications.menu. Simply creating this symlinc in ~/.config/menus seems to solve the problem with kde plasma: ln -s /home/cendio/.config/menus/applications.menu /home/cendio/.config/menus/kf5-applications.menu
