I want to change the default file explorer from nautilus to Thunar. I searched hours around the web and followed all the advices but nothing did work.
What my expected result is: When double-clicking on a folder on the desktop Thunar should open.
My system is VERSION="18.04.3 LTS (Bionic Beaver)"
What I've done so far:
I changed all some files (so all files in which nautilus was set to open folder) in /usr/share/applications/ to use Thunar:
user@computer:/usr/share/applications$ grep -i Thunar * (and exclude the Thunar-Files itself)
backup-mimeinfo.cache:inode/directory=org.gnome.baobab.desktop;nautilus-folder-handler.desktop;org.gnome.Nautilus.desktop;Thunar-folder-handler.desktop; defaults.list:inode/directory=Thunar-folder-handler.desktop
defaults.list:x-directory/normal=Thunar-folder-handler.desktop
mimeinfo.cache:inode/directory=org.gnome.baobab.desktop;nautilus-folder-handler.desktop;org.gnome.Nautilus.desktop;Thunar-folder-handler.desktop;
nautilus-autorun-software.desktop:TryExec=thunar
nautilus-autorun-software.desktop:Exec=thunar
nautilus.desktop:Exec=thunar
nautilus.desktop:Exec=thunar
nautilus-folder-handler.desktop:Exec=thunar
nautilus-home.desktop:Exec=thunar
nautilus-home.desktop:Exec=thunar
org.gnome.Nautilus.desktop:Exec=thunar
org.gnome.Nautilus.desktop:Exec=thunar
thunar-volman-settings.desktop:Exec=thunar-volman-settingsI changed the Mime-Association
sudo xdg-mime default Thunar.desktop inode/directory application/x-gnome-saved-search
I checked the mimeinfo.cache:
user@computer:/usr/share/applications$ grep inode mimeinfo.cache inode/directory=org.gnome.baobab.desktop;nautilus-folder-handler.desktop;org.gnome.Nautilus.desktop;Thunar-folder-handler.desktop;
I changed mimeapps.list in my home-directory:
user@computer:~/.config$ cat mimeapps.list
[Added Associations]
application/x-nautilus-link=Thunar-folder-handler.desktop;
inode/directory=Thunar-folder-handler.desktop;
[Default Applications]
inode/directory=Thunar-folder-handler.desktop
application/x-gnome-saved-search=Thunar-folder-handler.desktop
But it's still not working. So in principle my only question: How does ubuntu decides what to to when double-clicking on a folder placed on the desktop?
