When I look in my SD card, caja throws up a stupid blue banner saying "The media contains digital photos"
Not entirely sure. Related to gthumb-import.desktop, which has the text "Import with gThumb" which is in /usr/share/applications/gthumb-import.desktop
Nothing in mateconf-editor to tweak as well. Bad coding...
Uninstalling gthumb and any other image program got rid of the banner, but that is not desirable.
Open/create the file /home/$USER/.local/share/applications/mimeapps.list and add these lines (reference http://www.freedesktop.org/wiki/Specifications/mime-actions-spec)
then update the mime database and killall instances of caja
sudo update-mime-database /usr/share/mime
Had a similar problem with the Downloads directory, same stupid blue banner again, "Personal File Sharing", "You can receive files over Bluetooth into this folder".
This time I uninstalled the bluetooth sharing agent:
and did another pkill caja
in mateconf-editor the key /desktop/mate/file_sharing/bluetooth_obexpush_enabled looks suspicious
To all the retards that want these helpful hints, download Ubuntu please or better yet, purchase Windows / Mac OS.
