Forgive the melodramtic title. I do have a problem, however. I just logged into my KDE 4.4 desktop today to find that my KMenu has absolutely no entries in the Application tab. And that KRunner has no apps listed either. I can still run all my apps (so I know they are there), but there's no desktop entry for them.

This is brand new to me, but I've heard of others with the same problem in KDE 4. One fellow suggested removing the /var/tmp/kdechace-[user] dir would help; it didn't help in my case, however. This seems user specific, bu rm'ing my .kde4 directory didn't help either. Anyone know what is doing this?

Try running "kbuildsycoca4 --noincremental".

If that doesn't work, check for anything in ~/.local/share/applications and ~/.local/share/desktop-directories and remove them. Removing ~/.config/menus might help also.

Afterwards run "kbuildsycoca4 --noincremental" again.

If none of this works, and it is reproducable on a new user, please check to ensure all updates are installed, and that /etc/xdg/menus/ exists and contains a file named "applications.menu"

Hmm, looks like I am missing the applications.menu in /etc/xdg/menus. I think I know why too; I just removed my GNOME desktop installation on this system and probably removed some shared package in the process. Oops...

Ok, I figured it out. When I removed my GNOME desktop I also removed the desktop-data-opensuse package, which contains all the openSUSE *.menu and *.desktop files (I had mistaken it for the "desktop-data-opensuse-extra" package, which contains extra GNOME wallpapers). I installed that and everything is ok now.

Whew... that was a bit scary.

Thanks for the help!
