I have a Ubuntu MATE desktop on which my Applications menu crashed yesterday and disappeared into the cosmic bit bucket. In the process of trying to repair it (which I managed to do), I followed an instruction I found online and issued
mate-panel --reset. Big Mistake! All of my rather complex panels and drawers which I'd spent considerable time putting together followed my Applications menu into cyber-nowhere!!
I note that all the details of application launchers and drawers are still there, in
~/.config/mate/panel2.d/default/launchers/*.desktop files, but are not expressed in the (new) side panel. It looks as if the integration is done in the file
~/.config/dconf/user which is a binary file.
Is there any way to re-integrate these existing *.desktop files into the panel without totally re-creating them from scratch?
