How do I fix some broken thumbnail preview settings in Nautilus?

  • 772

Okay, I wanted previews for psd files in Nautilus. So I tried the scripts found on this page: How to make Nautilus display .psd thumnails?

This did not work, so then I found this maintained PPA, and I decided to try that.

It did not seem to work either. But it does krita files in addition to psd so I made a krita file and that preview worked!

So I think the issue is that the first script I ran somehow messed up my settings so that the installed PPA won't work.

Any clue on how I can reverse the effects of the first script? I don't know enough about the internals of Linux etc to really manipulate this stuff very well. I can use Linux, and do web development but I'm not really clear on how it actually manages thumbnail settings etc. I assume that's something that the shell does etc.

  1. Revert what the script did

    sudo gconftool-2 --unset /desktop/gnome/thumbnailers/[email protected]/enable
sudo gconftool-2 --unset /desktop/gnome/thumbnailers/[email protected]/command
sudo rm -f /usr/lib/psdthumbnailer /usr/share/thumbnailers/photoshop.thumbnailer
## Optionnal, you may want to keep ImageMagick
## sudo apt-get remove --purge imagemagick

    If needed, here is how to clean the Thumbnails cache
    Thumbnails will be re-ceated while browsing directories

    rm -rf ~/.cache/thumbnails/*

    Install the Ubuntu PSD thumbnailer

    sudo apt install librsvg2-common
