I was finally able to completely circumvent this problem by enabling *both*
indirect rendering and loose bindings for compiz (by modifying the appropriate
line in /usr/bin/compiz). Compiz runs really fast now (a lot (!) faster than
with indirect-rendering only and even more faster than without both).
I'm running an unsupported combination of software versions however, so could
someone check whether this works with plain Intrepid, too?
I am running:
Ubuntu 8.04 with stock compiz 0.7.4
Nvidia driver 180.29, installed manually
on a Quadro FX 370 (dual monitor setup)
Without loose-bindings I especially had very bad performance when
running OpenGL applications with compiz enabled.
I now have in my /usr/bin/compiz:
build_args()
{
[...]
if check_nvidia; then
if [ "x$INDIRECT" != "xyes" ]; then
COMPIZ_OPTIONS="$COMPIZ_OPTIONS --loose-binding
--indirect-rendering "
fi
fi
}
