Enabling metacity compositing manager

I’ve just switched for a few days to GNOME and I remembered a discussion about activating metacity compositing manager. I haven’t found the information I was looking for on the Internet, but Olivier told me his “Jus de cuisson” mentioned a discussion thread back in January.

I eventually found the discussion thread, but what was stated was wrong (well, it was probably true when the message was sent, but not anymore) : the compositing manager is not enabled by default.

The compositing manager doesn’t give you as much effects and eye-candies as compiz, but it’s enough for a daily and professional usage. Here’s the list of things enabled with the compositing manager of metacity (quote from Frederic Crozat):

-Composited managed desktop (some applications might use it, like transparent applications such as gnome-terminal and probably others)
-brand new alt-TAB with screenshot of applications and highlight of to-be-focused app
-nice shadow around windows (now, you can have an idea on the initial design of Ia Ora window theme :)
-NO openGL required !!

So, here’s how you can enable it (should work with any distro using a recent enough metacity) :
gconftool-2 --type bool --set /apps/metacity/general/compositing_manager true
To disable compositor :
gconftool-2 --type bool --set /apps/metacity/general/compositing_manager false

    It’s useful also when you want to use avant-window-navigator as it needs compositing support.
    Before you had to use Compiz to be able to use AWN

    It was enabled when the message was written, but disabled again a few weeks later as it just caused too many problems – for several users, it broke Metacity.

    @Fabrice : Excellent, I’m gonna try AWN right away.

    @Adam : Yes, I must admit I haven’t tried yet many applications and didn’t play a lot with metacity.

    I m trying it. I was looking desesperatly for a mean to use awn without compiz on my thinkpad whose 3D card is not good. The only little bug I have for the moment is it slashes the screen in firefox for a few milliseconds when i go too fast scrolling a page.

    For information, I found out Miro is unable to play video files when you’re using AIGLX and compositing… So I went back to a non-composited desktop because I use Miro a lot.
