Re: geforce 8800gtx, 9746 driver and X lockup
I see two problems in your bug report. First, you're not using the glx module that ships with the NVIDIA X driver. Second, you don't have the required libwfb library, which also ships with the NVIDIA X driver. Both of these indicate that the NVIDIA X driver was not correctly or fully installed.
(II) LoadModule: "glx"
(II) Loading /usr/lib/xorg/modules/extensions/libglx.so
(II) Module glx: vendor="X.Org Foundation"
compiled for 7.1.1, module version = 1.0.0
ABI class: X.Org Server Extension, version 0.3
(EE) NVIDIA(0): Need libwfb but wfbScreenInit not found
