nvidia in Fedora 9
…doesn’t work properly (at least on my laptop, using a GeForce 7000M). the reason for this is that Fedora 9 uses the latest version of xorg and NVidia‘s driver does not yet work with it (3D is not fully working).
To get stuff at least minimally working, you need to downgrade your xorg RPMs to the Fedora 8 versions.
Unfortunately, KDE4 appears to require fully working GLX in order to display the kicker (or whatever the hell they’re calling it now), so my KDE is slightly crippled at the moment. A pity, really, as KDE4 is beautiful and almost as usable as 3.5 was.
