Adding NEF preview to Linux Mint file manager Nemo

Nikon Logo

If you want to be able to preview NEF (Nikon raw) images in Linux Mint’s file manager Nemo, you need to do the following:

  1. Open Preferences window for Nemo file manager from Edit -> Preferences menu
  2. Switch to Preview tab within the Preferences window
  3. Set “Show Thumbnails” to Always if you want to show thumbnails on remote drives
  4. Set “Only for files smaller than” to 100 MB
  5. Install the following packages from Software Manager UI:
    • gnome-raw-thumbnailer
    • libopenraw1
    • libopenrawgnome1

Note: Browsing remote/network directories will be sloooooooow if you enable thumbnails for remote drives.

Reconnecting a bluetooth mouse in Linux Mint upon reboot

Logitech Ultrathin Mouse

I use a bluetooth mouse with my laptop (never could understand manufacturers pushing their proprietary USB wireless peripherals – why take up a USB port when all laptops have bluetooth built-in). When I installed Linux Mint (version 17.3) it has connected to my mouse just fine and I was able to use it with no issues. However the OS would never reconnect with the mouse upon reboot which is a hassle – you have to remove/add the device every time. Clearly not the way to go.

This is what I’ve done to get the OS remember the mouse and it’s settings.

  1. Put your mouse in a discoverable state (there is usually a button on the mouse somewhere for this)
  2. Open terminal and run the following command that should give you a MAC address for your mouse:
    hcitool scan
  3. Once you’ve obtained your mouse MAC address (should look like XX:XX:XX:XX:XX:XX), run the following in terminal:
    bluez-simple-agent hci0 XX:XX:XX:XX:XX:XX
    bluez-test-device trusted XX:XX:XX:XX:XX:XX yes
    bluez-test-input connect XX:XX:XX:XX:XX:XX

Now you should be good to go.
