gnome-sushi
should work out of the box. You might need to reboot, or restart nautilus. Like so: nautilus -q
.
If that still doesn't work, try reinstalling it: sudo apt-get purge gnome-sushi
and install it again: sudo apt-get install gnome-sushi
. Restart nautilus -q
. This should work.
For gloobus, when installed with the webup8 ppa, like so:
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install gloobus-preview
It should be noted that you need extra dependencies to get it fully functional and to integrate it better with your file manager of choice. (nemo, nautilus)
This is for previewing documents a little better, although it is not optimal:
sudo apt-get install unoconv gnumeric
And the second is to integrate gloobus with either nautilus or nemo:
If you have nautilus
:
sudo apt-get install gloobus-sushi
Or if you have nemo
:
sudo apt-get install nemo-gloobus-sushi
Both applications needs to be restart before continuing: nemo -q
/ nautilus -q
