Works for me, NVIDIA 6111 driver, xorg-x11-6.8.1-3,
xcompmgr, transset and everything...
VendorName "Videocard vendor"
BoardName "NVIDIA GeForce FX (generic)"
Option "RenderAccel" "true"
Option "Composite" "Enable"
Works fine with my computer. I'm using the vendor provided nvidia

Thanks for the report. The COMPOSITE extension will be supported
in a future OS release, however at this time it is only an
experimental X server extension. In order to use COMPOSITE, you
must manually configure it by hand as you've done in your config
file, and you must install a compositing manager such as 'xcompmgr'
which is not included with Fedora Core. You can get 'xcompmgr'
from freedesktop.org if you don't already have it or a window
manager that has a built in compositing manager.
Several people have reported to have gotten COMPOSITE to work,
so it is possible that your X server may be misconfigured or that
the vendor driver you are using doesn't support your combination
of OS/X server/kernel/hardware.
If you experience any problems with the COMPOSITE extension, please
report them directly to X.Org, so that any problems that arise
can be investigated by X.Org developers and fixed before COMPOSITE
becomes an officially supported X server extension.
http://bugs.freedesktop.org in the 'xorg' component
Also, if you are using unsupported proprietary video drivers and
having any difficulties with them, you can try any of the following
support mechanisms to try and get assistance:
- The hardware vendor's website. Be sure that the vendor claims
that their drivers officially support the OS release, X server
release and specific functionality you are wanting to use. In
particular it may take hardware vendors several months before
they have added support for new X server functionality into their
drivers and officially support it on the OS release you are using.
- The hardware vendor's public help forums (if any). Many hardware
vendors (such as Nvidia) have public web support forums.
- The X.Org, freedesktop.org and/or XFree86 mailing lists.
- The Red Hat public mailing lists.
Setting bug status to "NOTABUG". If you continue to have
difficulties, you may wish to use one of the above suggested
support forums for assistance.
Composite is working for me very nicely using the nVIDIA 6111 driver,
FC3t2 with these package versions:
I have built the kernel module independently but have installed the
driver with the Livna.org package. Composition works in both Gnome
(metacity) and XFCE4 using xcompmgr from freedesktop.org cvs
(26sept2004). I use the command line:
xcompmgr -c -C -f -F -o 1.0 -I 0.08 &
Some windows have slight issues but the majority work correctly, even
flash objects drawn in Firefox are composited with no major slowdowns.
Firefox was reported elsewhere to crash X when composited.
plays nice here too with latest nvidia & rawhide.
openGL windows don't render correctly (overlay issues, x crashing
sometimes..., but removing the composite config lines from xorg.conf makes
openGL work fine again...)
and sometimes windows don't get updated and are tearing a bit,
but nevertheless its working great for a *preview* ! :)
ps. here is an mail from nvidia about this topic i got

Greetings, Lars. Thank you for your email. We are investigating
adding GLX support for Damage/Composite in a future release, but
I do not have an ETA at this time.
Thanks for your interest,

here is how-i-did-it
in /etc/X11/xorg.conf i had to add:
Option "Composite" "Enable"
and in the nvidia device section of the same file:
Option "RenderAccel" "on"
after restarting X one needs the xcompmgr
get it with:
cvs -d :pserver:firstname.lastname@example.org:/cvs/xapps login
cvs -d :pserver:email@example.com:/cvs/xapps co xcompmgr
make it, and start it with "xcompmgr -c -f -F" when X is running.
I add option "GLXWithComposite" in NVidia's driver in xorg.conf and
now, GLX AND Composite run fine.
Bugs with GLX Windows in move windows and GLX was always in front but
This bug it's the same with ATI drivers.
When Composite is ''on'' the ATI Open glx is don't load.
But mesa open gl is load. also the 3D hardwear don't work.
the driver ati used is : fglrx_6_8_0-8.12.10-1.i386.rpm
the kernel is the last kernel 188.8.131.52.14 or/and 2.6.10-xx 770.
Please ! don't forget Ati !!!
(sorry for my english!)
ATI isn't reading this bug report most likely. You'll need to contact
ATI directly if you want them to add this support to their drivers.
We do not even ship ATI's fglrx driver, so your request in our bugzilla,
definitely isn't going to be seen by anyone who can make it happen.
Visit: http://www.ati.com go to the drivers section, and somewhere in there
is a link where you can provide ATI feedback. I don't remember the exact
URL, but it shouldn't be hard to find, as long as they still have the
web form there.
Hope this helps.
