SD card, RAW and Ubuntu

I wanted to upload some photos on my Dell XPS 17, but encountered some issues to view them

The SD card is not detected when inserting it in the reader.

The trick is simple :

sudo su -l
echo 1 > /sys/bus/pci/rescan

RAW are not readable

I had to actions to do it :

install the package : gnome-raw-thumbnailer (By the way, unable to add apt:// link in Wordpress :-( )
if missing create the following file <code>/usr/share/thumbnailers/raw.thumbnailer</code>, that seems not included in the package, with this content :

[Thumbnailer Entry]
Exec=/usr/bin/gnome-raw-thumbnailer -s %s %u %o

then restart Nautilus via the menu (File → Close all windows) or nautilus -q
