[gentoo-amd64] Troubleshooting XComposite

[Sebastian Redl]

Hi,

When my hard-disk made suspicious noises recently, I decided to replace
it - be safe rather than sorry - and use the opportunity to do a
complete, fresh install of my system. The new system is up and running
(OpenOffice troubles aside), with the added advantage that I finally
managed to get to the most recent ATI binary driver version instead of
that stone-age version that happened to not hang my system under the old
setup.

With the new driver, I want to use its AIGLX capabilities. However, I'm
having trouble getting XComposite to work. I have it enabled in xorg.conf:

Section "Extensions"
        Option      "Composite" "Enable"
EndSection

Xorg.0.log agrees:

$ grep -i composite /var/log/Xorg.0.log
(**) Extension "Composite" is enabled
(II) fglrx(0): Sync:  Separate  Composite  SyncOnGreen
(II) Initializing built-in extension COMPOSITE

I've got direct rendering and the RENDER extension:

(II) fglrx(0): Direct rendering enabled
(II) Initializing built-in extension RENDER

And the damage protocol:

(II) Initializing built-in extension DAMAGE


Unfortunately, xdpyinfo disagrees:

$ xdpyinfo | grep -i composite
$

And so does KDE4 (System Settings, Desktop, Desktop Effects), telling me
that compositing is not supported on my system, and that XDamage and
XComposite are not available.


I can't find any information on troubleshooting the problem. Can you
help me out?

Full xorg.conf is attached. I've enabled the xcomposite use flag and
done the Paludis equivalent of emerge -N world.
