Sometimes I get the error that seems to be described in this thread (see this post for an image). However, despite it being an error, I actually enjoy the theme (or lack thereof) with it's carved buttons, no rounded corners and clear boundaries between elements. Maybe it just feels nostalgic, but anyway -- I want to know how to keep that theme (non-theme?) permanently.
Btw, it doesn't seem to be the Clearlooks theme, which according to what I read is the default Gnome theme, so I'm inclined to believe that it is Gnome unthemed.
1) Open the file "%gconf.xml" at "~/.gconf/apps/metacity/general" (
gedit ~/.gconf/apps/metacity/general/%gconf.xml)2) Search for
<entry name="theme" mtime="1335845353" type="string"><stringvalue>Radiance</stringvalue>
3) Change "Radiance" for a non existing theme like "nonexistingtheme",
4) Save,
5) Logout and log back in.
6) Enjoy ;-)
Based on this post, I am inclined to believe that the "unthemed" interface was actually the Raleigh theme.
I can't confirm that's true because the image linked to in the question has been removed from tinypic, so if someone knows better (any GTK whizzes around?), please comment below :)
