How to mount a digital camera for the right applications?

  • 772

Whenever I plug by digital camera in, a nice media-icon pops up. Great! !

When I right click on this icon, I can only open Rhythmbox or VLC-media-player. Both applications are rather senseless to be used here. When I want to download photos (be it by means of F-Spot, Shotwell or Picasa) I have to unmount the camera first. This seems to me rather illogical ? Why is the camera mounted if you have to unmount it to be used? How can I make that the digital camera is being mounted for the right applications? It looks strange to me that one has to unmount a device before one can use it!

Camera model : Canon PowerShot SX20 IS (new id has been added for this camera in libgphoto2 2.4.9. The packagemanager tells me that libgphoto2-2 is installed, version 2.4.8-0ubuntu2 => it looks like libgphoto2 can't read the camera? Anyway, the PTP/MTP- mode works fine)

  1. I think you can handle this through the Nautilus preferences.

    1. Open Nautilus (Places -> Home Folder).
    2. Click the Edit drop down menu.
    3. Choose Preferences.
    4. In the File Management Preferences window, click the Media tab.
    5. The Media Handling section should allow you to configure the system to behave the way you want when you attach the camera.[1]

    [1] The options next for Photos, include: Ask what to do, Do Nothing, Open Folder, Open F-Spot, Open with other Application...

  2. Just a stab in the dark, but if you temporarily comment out the following lines in /lib/udev/rules.d/45-libmtp8.rules, does it help at all?

# ATTR{idVendor}=="04a9", ATTR{idProduct}=="31e4", SYMLINK+="libmtp-%k", MODE="660", GROUP="audio"
