Comment # 13 on bug 1012138 from Ronny Peine

Hi,

tumbler seems not to be any dependency, so it could be possible.
As I have seen we could also try to set "thunar/misc-thumbnail-mode" to
"THUNAR_THUMBNAIL_MODE_NEVER" through xfconf. Don't know how to integrate this
systemwide.

Most likely it could be integrated through creating an xfconf xml file e.g.
/etc/xdg/xfce4/xfconf/xfce-perchannel-xml/thunar.xml
And putting the desired properties there.

Maybe this file looks like this:
<?xml version="1.0" encoding="UTF-8"?>

<channel name="thunar" version="1.0">
  <property name="misc-thumbnail-mode" type="string"
value="THUNAR_THUMBNAIL_MODE_NEVER"/>
</channel>


Haven't tested this. But could be a nice start. This setting hopefully doesn't
lock the setting, so the user can still change it.

Kind regards,
Ronny
