hi, i use an self compiled and patched 2.6.39 rt kernel and active rtirq script with an
nvidia proprietary driver without any problems. also i run my kde desktop with compiz
window manager and a lot of nice 3d effects. most curios side effect is, that compiz in
combination with really low latency settings under jackd will perform much better than in
combination with kwin or metacity. i use the nvidia-installer instead any of the
distribution packages. the only more or less a bad side effect is, that you have to
reinstall the nvidia driver all time if an system update will update xorg packages.
system info:
kernel 2.6.39
nvidia-installer version 290.10
card is nvidia quadro NVS 140M
