[SOLVED] Gnome shell 3.8 excludes some apps (.desktop) when searched

Hello there. I'm having this problem with gnome-shell 3.8, which is behaving inconsistently towards .desktop files. I have tried finding a pattern on those application launchers located under /usr/share/applications/ that are successfully found when I type their names in the shell, and comparing them to the ones which aren't. I have also modified some launchers without luck. Every installed app is shown at the "All" section, so this has nothing to do with NoDisplay=true. So far these are my clues:

  • Guest account has all programs "searchable", so I suspect I should blame myself instead of Gnome 3.8.

  • Gnome core packages (those in the gnome group) can be searched, the rest of Gnome (gnome-extra) cannot though.

  • The only searchable third-pary apps are videogame emulators, to be specific: desmume, m65py (mupen64) and dolphin.

  • This affects both official and AUR packages.
    EDITED:

  • Permission are consistent across .desktop files too.

Any ideas? Should I create a new user and stop asking for help?

1.Maybe your settings got messed up when you updated. Try creating a new user and see if you can reproduce the issue.
or
2.Delete .config folder in your home folder and It will repopulate the settings from scratch.

Deleting .config/ makes no difference at all, new users work fine however. I think it's time to start backing everything up with cp -a and then transiting to a brand-new user.

Just one more question: If I make the new account with exactly the same username (obviously after deleting current one), will I be able to restore all my stuff like settings and firefox session by simply pasting from backup to new user's home? Or is it that there's something like a unique hash per user no matter if their names are the same, or any other kind of sorcery that won't let me restore with ease?

Try running: sudo update-desktop-database

I'm kidding, update-desktop-database didn't work. According to update-desktop-database --help and freedesktop.org that command only builds a database of MIME types and their preferred application.

Re: [SOLVED] Gnome shell 3.8 excludes some apps (.desktop) when searched

This experience has taught me many things about Unix-like permissions. It turns out that the user ID (UID) is what is actually considered to be the owner of each file/folder and the user name (USER) displayed by nautilus simply wraps the UID, so even if I create 2 users with the exact same name at different times their UIDs won't match (they seem to be incremented by one each time a new user is created and the count doesn't decrease if an account is deleted, thus assuring unique and unrepeatable users per system). Therefore, "cp -a" is futile for pseudo-moving stuff from one user's home to another unless you can override the UID and Group ID, which would be stupid because  cp -a is used in situations where you don't want them to be overridden unlike sole cp. I must admit ignorance on chmod and chown, so my final option is literally moving my info to a storage media lying outside of the filesystem: slow but workable.

I suggested it because it fixed a similar issue for me. Thunderbird wasn't showing anywhere in the gnome 3.8 overlay and I had it installed, after running that it showed up as expected when searching.

Re: [SOLVED] Gnome shell 3.8 excludes some apps (.desktop) when searched

Problem is gone! After comparing my old .local/share against a new user .local/share I noticed some critical differences: I had applications, desktop-directories and mime folders whereas new user did not. My installation is about 4 years old; Gnome 2 stuff leaked and something might have become deprecated, conflicting with Gnome 3.8... dunno.

A file called X-GNOME-Other.directory inside .local/share/desktop-directories was creating the whole trouble. I removed it, restarted gnome-shell, and everything returned to normality.

@hadrons123, @bwat47: thanks for your advice.
