Metacity and AWN in Lenny

Earlier today, I posted my setup of Compiz and AWN.  But then, I found that, my system is taking too much CPU (mostly xorg).  Even during video playing (MP4), xorg hits 90% CPU.  Then, I started to find another composite window manager to replace Compiz.  Metacity is a compite window manager, but when I start AWN, it said:

Error: Screen isn't composited. .....blah blah

Then I try to look around in the net and finally found that, I have to turn on the “composite manager” support in metacity explicitly.  It is off by default.  So, just fire up the gconf-editor, edit the key:

/apps/metacity/general/compositing_manager

set it to true (tick the check box).  That’s all.  My system is now as fast as before and with the AWN!    Well, there goes all the compiz effects, but usability is more important.

Finally, ~/.gnome2/session (copied from /usr/share/gnome/default.session) has the following content:

[Default]
num_clients=3
0,id=default0
0,Priority=10
0,RestartCommand=gnome-wm --sm-client-id default0
1,id=default1
1,Priority=40
1,RestartCommand=avant-window-navigator –sm-client-id default1
