x-server starts but i can see this error in terminal one (when i press ctrl-alt-F1)

This text repeats several times

i got the error when installing nvidia drivers from website after the install with apt-get... (because there appears to be no 3d acceleration in the drivers with the distro) I think that might be the problem and I don't know where to start looking to resolve it.

I removed the apt-get driver nvidia-glx but it didn't change a thing and i tried to comment out the lines about /dev/wacom in xorg.conf but then x won't start so that doesn't solve the problem.

running kubuntu 6.6

EDIT : reinstalled kubuntu and off coarse the problem is gone too. Still I don't know how to install the nvidia drivers correctly without apt-get ...

Did you try the binary nvidia driver from the site? It comes with good instructions. You can even set up twinview on different-sized monitors.

There are tons of walkthroughs on the net:
