Do you have Load "glx"in the "Module" section of /etc/X11/XF86Config (or /etc/X11/xorg.conf)?

Depends a bit on which distro you're using ...

It may be as trivial as editing /etc/X11/XF86Config
and loading glx in the server section ....

Or enabling dri with correct permissions.

no i dont know how ...

How ???

Code:

Section "Module"

# This loads the DBE extension module.

    Load        "dbe"   # Double buffer extension

# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.
    SubSection  "extmod"
      Option    "omit xfree86-dga"   # don't initialise the DGA extension
    EndSubSection

# This loads the Type1 and FreeType font modules
    Load        "type1"
    Load        "speedo"
    Load        "freetype"
#    Load        "xtt"

# This loads the GLX module
    Load       "glx"
# This loads the DRI module
    Load       "dri"

EndSection

Code:

 Section "DRI"
    Mode 0666
 EndSection

That's what my relevant sections look like...

As to how: use your favourite text editor.

Tink

Why do they say this ;If you already have an X config file working with a different driver
(such as the 'nv' or 'vesa' driver), then all you need to do is find
the relevant Device section and replace the line:

Driver "nv"
(or Driver "vesa")

with

Driver "nvidia"

In the Module section, make sure you have:

Load "glx"

You should also remove the following lines:

Load "dri"
Load "GLcore"
I have the same problem on some dist. and others go without a hitch,never did leave load dri in there may try that next time.

oops!

Probably because ATI chipsets are known
to run very poorly with nvidia drivers?
