Re: OpenGL, GF2 okay, GF4 freezes
Well it seems that you do have a problem, as your glxinfo output states that you don't have direct rendering enabled. (Which seems weird as the rest of if look ok)
This is a snippet of my glxinfo output:-
name of display: :0.0
display: :0 screen: 0
direct rendering: Yes << This line here...
server glx vendor string: NVIDIA Corporation
server glx version string: 1.3
server glx extensions:
GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_SGIX_fbconfig,
GLX_SGIX_pbuffer, GLX_SGI_video_sync, GLX_SGI_swap_control
As you can see from the output that in mine it states that I do infact have direct rendering enabled.
Are there any errors in X startup?? I'm going to have another look at your XF86Config files etc. And see if I can see anything that I may have missed.
