nVidia drivers installed but not recognized

[mmaleck]

Hello - I am sort of an newbie/internediate user, but in terms of this topic I am definitely a newbie, hence the post here.

I am running FC5 release 2.6.16-1.2090_FC5smp, and my graphics card is a Quadro FX 1000 (NV30GL).

I have *some* nvidia drivers installed, and my xorg.conf seems to reference these correctly.

Here is the problem:

When I am logged in as root, the nVidia drives are "found":
glxgears gives me a FPS of about 2000. Not great, but hey.
glxinfo indicates that the nVidia drivers are being used.

BUT, logged in as myself (mmaleck):
glxgears --> FPS ~500, because
glxinfo indicates that the default driver (MESA) is being used instead.

I have looked around, and I couldn't find any direct reference to this problem, and I've tried a few things. My lack of experience has me going in circles, so any tips on what could be causing this and where to start would be greatly appreciated.

Can you post your xorg.conf? Also, the X log file (/var/log/Xorg.0.log) might have some useful info.
