[FC6] Installed 9629/9631, I can't get into graphical login screen in level 5...

[LendyZhang]

Hello, everyone.
I installed nVidia official driver 9629/9631 in FC6, and I can't get into graphical login screen in level 5 now...
Start FC6 in level 5, but result in a text login screen just like level 3. (Altho I can press Ctrl+Alt+F7 to go back into gdm, I really don't want to do this all the time T_T ).

I've been in this trouble for a long time...hoping that the new nvidia official driver would fix this problem...however....the 9631 driver is still the same....

Maybe I could reinstall the kmod-nvidia driver...It surely would solve this problem.
However, I do want to use the nvidia offical driver. Because:
(i) the kmod-nvidia does not update the GL headers.
(ii) Maya7.0 cannot run with kmod-nvidia driver (except replacing the libGL.1.2 with nvidia/libGL.1.0.96xx)

So...
Does anyone get any ideas to fix this problem?
