No video thumbs in Ubuntu Desktop (how-to fix)
How-to solve the lack of video thumbs in Ubuntu Desktop
Since I installed Ubuntu Desktop 64b some video files had no thumbs preview in Nautilus. After 3 months I decided to fix this, and it's a very easy and fast fix.
Open terminal Window and write:
$ sudo apt-get remove totem
$ sudo apt-get install totem-xine
Finally we just need to clear the thums cache by deleting the fail folder:
In Terminal window write:
$rm -rf /home/yourusername/.thumbnails/fails
Done... just open nautilus with all the video thumbs this time
