Here is a BG for a Linux OS that I "HIGHLY" Recommend...

It's got Beryl as it's BASE Desktop.
But can easily be changed top Metacity.

It can also have the Desktop Config easily changed in the Bootup Screen.
Has almost every different Linux Desktop around already to go, JUST Pick and CHOOSE...

The Gnome and KDE Desktop have both been Merged together to offer the Best of Both Worlds...

It's Based off Gentoo, So you know it's SOUND...

A complete OS with no need to add anything UNLESS you'd like...

And the Best Part I like is it's GOT GAMES & LOT's of them.

If your interested...
Just Google Sabayon and it'll take ya right there...

ENJOY!!!
