Hello all,
I noticed Xfdrake does not display the color bars when you click Test. Having a Mandriva installation handy made this easy to figure out.
Mageia has the file: /usr/share/mga/xfdrake/xfdrake-test-card.png
and XFdrake is looking for it in: /usr/share/mdk/xfdrake/xfdrake-test-card.png
So, to fix it just make the path /usr/share/mdk/xfdrake/ and copy the file xfdrake-test-card.png to there.
I don't know if there is a bug report yet but I'll go look.
