Troubleshooting menu issues

If all your application menu icons and programs disappeared after installing a new app, check that the space on your root filesystem has not been (almost) completely filled. You can see the remaining space by opening an xterm window and issuing the command 

df -h

Check the output line where the column "Mounted on" corresponds to "/". If that partition has been used by 99% or 100%, chances are your menu has disappeared for this reason.

The next thing is to free some space. Most likely, you will be able to get rid of some multimedia files in /home/user/MyDocs/.images or /home/user/MyDocs/.sounds - but check also .documents and .videos.

After this step, the right command to see your menu again will be 

cp /etc/xdg/menus/applications.menu /home/user/.osso/menus/ ; update-desktop-database

NOTE: this must be issued as root. You have a root enabling package installed, haven't you? See Root access for details.

After that, you'll have a menu again. Though, it will be quite messed, and the majority of items will be in the Extras menu: you'll have to exercise your patience by tiding it all again. The quickest way is going to the Control Panel, into the Panels submenu, where you'll be able to move all those applications from Extras to other cathegories, or create/modify/cancel the submenus.
