Xlib: extension "GLX" missing on display ":0.0".

I have problem with my nVidia G98 [GeForce 9200M GS] (rev a1) over 3 months now.
this card only works only when i load “nv” and not “nvidia”
I search forums and i insert load module glx and this to my xorg.conf
Section “Extensions”
Option “Composite” “Disable”
EndSection

any suggestion ?

If the default Nvidia driver from the Ubuntu repositories doesn’t work, try some of the more recent drivers that are provided through these repositories:
http://www.avenard.org/files/ubuntu-repos/

Browse through the stable or unstable lists to get the package names, and then install them with apt-get once you have added the new repositories.

Always remove the default Ubuntu nvidia drivers first though.

This project used to be good at installing recent nvidia drivers, but it seems a little out of date today:

What ever you do, if you are using Ubuntu I don’t recommend trying to install the binary driver manually, it has become really complicated, if not impossible. So if you are editing your Xorg.conf file…don’t…it will just bring you pain and grief. At least, that’s my personal experience.

I put in my sources.list the repositories fromhttp://www.avenard.org/files/ubuntu-repos/

I remove all nvidia drivers
sudo apt-get remove --purge nvidia-glx (to remove ALL traces of ubuntu’s nvidia driver)

I browse the stable list but there is a confuse of which package to choose.

After 1 day …
Format my linux.
i’m without nvidia drivers . because i take a black screen.
running Xserver-xorg-nv.

a glx package like nvidia-glx-195_195.36.15-0ubuntu1_i386.deb??

Yes, that’s what you need. I can’t guarantee it will solve your problems but it’s worth a try.
