?HOWTO: Beryl on Debian

Last week Jordi Fernández gave me a quick hands-on tutorial for a working Beryl setup on Debian. He owns a Dell Latitude D620 running Debian GNU/Linux just like mine, so leeching his setup was even easier for me. What sold me immediately into Beryl is that you don’t need to install Xgl.
Basically I edited /etc/X11/xorg.conf and added these lines to the Device section:

Option "RenderAccel" "true"
Option  "backingstore" "true"
Option "XAANoOffsetScreenPixmaps" "true"
Option "AddRGBGLXVisuals" "On"

and added a new section to the very end:

Section "Extensions"
        Option "Composite" "Enable"

My updated xorg.conf is available right here.
After restarting X (ctrl-alt-Backspace for lazy users like me) you can type this on a terminal:

$ beryl-manager &
$ beryl

I have the official nvidia drivers (1.0-8776) installed via module-assistant and a Beryl version that is kind of old (0.2.0+svn20070205-r3687+imudebian0, rather ancient in Internet Time). This worked immediately for me but Your Mileage May Vary.
There you have it. A working beryl setup in a few minutes. Thanks to Jordi for this tutorial and the rather impressive demo that followed, and to the Compiz and Beryl developers for their hard work.
