There is also now an officially recommended way to manage which thumbnails are generated in
tumbler, the Xfce thumbnailing service. Using the method described below means nothing will need to be uninstalled from the
gstreamer set of packages, and all other thumbnails (apart from video) will be generated.
However, it is important to note that this is only possible if you have
tumbler 0.1.27, although this will be at least the version in Raring (13.04). If you are on Xubuntu 12.10, you only need to enable the Xfce 4.12 ppa to get the latest version of
On the Xfce announce mailing lists for January 2013, it was noted that, regarding
This release ships a config file installed in the xdg directory to
control the various plugins (especially the priority). There is also a
cover download plugin (dependency is libcurl), but this has been
disabled by default.
How to enable and disable various plugins is explained on the Xfce official page, but briefly here's how it works. As noted in the explanation, if you want to customise the tumbler rc file, you can make a
tumbler folder in
~/.config and then copy
/etc/xdg/tumbler to that folder. The easiest way to do it is to use these commands from the xfce documentation:
mkdir -p $XDG_CONFIG_HOME/tumbler
cp /etc/xdg/tumbler/tumbler.rc $XDG_CONFIG_HOME/tumbler/
Now, edit the file with
and you will see something like this sample rc file, which has sections for video, image and other thumbnailer plugins.
As an example, you could find the section
Video Thumbnailers in the file above and set
Disabled=true in the sections for the
ffmpegthumbnailer and the
gstreamer plugins. Using this method you do not have to remove
gstreamer0.10-plugins to stop video thumbnails being shown.

If at some later point you find that you do not want to entirely disable the video plugins, you could instead use
Disabled=false to re-enable them and set a value for the
MaxFileSize, so that only files up to a certain size were shown. This would solve problems with high memory usage when thumbnails for very large files are being generated.
Note: after making any changes to
tumbler.rc , it is crucial that you log out and log in again. Video thumbnailing for those two plugins, for example, would not be disabled until you logged in again.
Remember, this will only work if you have
tumbler 0.1.27 or a later version installed.
