Comment 28 for bug 1069843

The
sudo mv ~/.cache/thumbnails ~/.cache/thumbnails_
ln -s ~/.thumbnails ~/.cache/thumbnails
did the trick for me as well.

I have noticed that ~/.cache/thumbnails only had permissions for the root user. Plus, it just had a size of just 24kilobytes, which means it did not really contain thumbnails. Which is why nautilus did not display any on 14.04.

In the end, I can work three times as long as before on battery and, as a bonus, I even can SEE the thumbnails. By simply fixing a symlink. I just can't understand why this bug, which is fixable THAT easy still is not fixed in the packages.

Btw, I did not notice the cpu consumption of nautilus in 12.04.4, which means it seems to be a regression after updating to 14.04.

And I updated just some days ago, so I guess the transition during the update to 14.04 still is buggy.
