How to select which application should be used by open containing folder?

  • 772

I have already read some questions and answers here and on the internet, but I wasn't able to solve my problem. I think it is related to having installed both ubuntu-desktop and kubuntu-desktop.

I have installed Ubuntu 14.04 on my laptop and also kubuntu-desktop. I mostly use the KDE sessions and hence I'd like all default applications to use KDE's programs, at the very least when running a KDE session.

Currently when I try to open a folder via Firefox's Open containing folder... Ubuntu's File application is launched. I'd like to see Dolphin instead.

I thought that firefox used xdg-open to open external files but this doesn't seem the case since:

xdg-open ~

Opens Dolphin in a KDE session.

In summary:

How can you specify exactly which application is used when clicking on Open containing folder...?

Note 1:

I have already set Dolphin as default:

$xdg-mime query default inode/directory
dolphin.desktop
$cat /usr/share/applications/defaults.list | grep inode
inode/directory=kde4/dolphin.desktop

Also in system preferences I have selected Dolphin as default file manager.

Note 2:

I have already tried to reinstall firefox in a KDE session (hoping this would trigger some re-configuration):

sudo apt-get remove firefox
sudo apt-get purge firefox
sudo apt-get install firefox

this doesn't change anything.

Note 3: I noticed the mimeinfo.cache file which contains:

cat /usr/share/applications/mimeinfo.cache.backup | grep inode
inode/directory=nautilus-folder-handler.desktop;baobab.desktop;kde4-dolphin.desktop;kde4-gwenview.desktop;kde4-kdesvn.desktop;nautilus.desktop;

However I have tried mving it (and restarting), but nothing changed. I have tried to replace the above line with:

inode/directory=kde4-dolphin.desktop;kde4-gwenview.desktop;kde4-kdesvn.desktop;nautilus.desktop;

But nothing changed.

  1. I'm use kde-standard over ubuntu-desktop, but my fix to this bug must work with kde-full and kubuntu-desktop over ubuntu-desktop too. Follow this steps:

    1. Rename nautilus:

      $ sudo mv /usr/bin/nautilus /usr/bin/nautilus.ubuntu

    2. Create a nautilus script in /usr/local/bin/ with the following content:

      #!/bin/bash
if [ '$KDE_FULL_SESSION' == 'true' ]; then
  if [ '${1}' == '--no-desktop' ]; then shift; fi
  /usr/bin/dolphin "$@"
else
  /usr/bin/nautilus.ubuntu "$@"
fi

    That's all! Maybe you have to kill all previous instances of nautilus using killall nautilus one more time.

    NOTE: I'm like the K Desktop Environment but I have to develop GTK programs: keeping the Unity desktop intact for debugging is a natural choice for me. My script allows launch both, Dolphin on KDE and Nautilus on Unity, without removing the last one with sudo apt-get purge nautilus, but I have to repeat this steps manually if the Nautilus deb package receives an update.
