I've installed Padman and urban terror in /opt .. created scripts to launch them in /usr/games, put icons in /usr/share/pixmaps and created .desktop files in /usr/share/applications (by copying the one for openarena and just changing the names).
So far so good, the games appear in the menu and I can play them.
After a reboot they're gone from the menu for every user, but I can get them back in the menu by simply opening a root terminal, moving the two .desktop files from /usr/share/applications to another directory and then moving them back again. And nothing more than this is required.
Have you run the following command? update-desktop-database Alternatively, you might want to use the following command: desktop-file-install http://manpages.ubuntu.com/manpages/precise/man8/desktop-file-install.8.html HTH Cheers, Peter -- Peter Reutemann, Dept. of Computer Science, University of Waikato, NZ http://www.cms.waikato.ac.nz/~fracpete/ Ph. +64 (7) 858-5174
