[Vanessa Ezekowitz <vanessaezekowitz@xxxxxxxxx>]

I'm changing this back to confirmed because it is clearly a userland
bug, not a driver bug - some users in the bug reports that are marked as
duplicates of this bug have indicated that they are running Intel and
ATI systems as well as Nvidia.

On my own system, I have an nVidia GF6800 card, using the 185-series
driver, running in Twinview  mode with two 1280x1024 Dell flat panel
monitors.    GLX is most definitely working fine - glxgears (whether it
is a benchmark or not) gives me over 20,000 frames per second, and apps
like Google Earth, OpenArena, and so on work perfectly fine.

XFCE's composite manager runs perfectly fine and has no issues
whatsoever that I've noticed.  I have of course tried disabling it
before attempting to run Compiz, but that of course doesn't work.

Compiz simply will not work for me. All the windows get hidden briefly,
then shown without window decorations for a moment, and then once in a
while I can *just* catch the window decorations changing to what Emerald
provides.  Whether Emerald is visible or not, compiz only lasts for a
split second before dieing with a segmentation fault:

The above is while running XFCE.  Gnome also fails to start compiz,
though the error it gives is a generic "couldn't be started" error
dialog.  I don't know what that 8bit pixmap format is about, as I'm
running in 24 bit mode.

On my husband's box, which has an even older nVidia MX4000 running the
96-series driver, with only one fairly non-descript 1280x1024 Dell flat
panel (i.e. no multi-head), compiz runs fine.
