see libglx.so installed xserver-xorg-core package
/usr/lib/xorg/modules/extensions/libglx.so

nvidia driver installation sets alternate libglx
lrwxrwxrwx 1 root root 19 2009-08-31 12:28 libglx.so -> libglx.so.185.18.36
-rwxr-xr-x 1 root root 1.3m 2009-08-31 12:28 libglx.so.185.18.36
in same path /usr/lib/xorg/modules/extensions
nvidia driver replaces /usr/lib/libgl.so driver version of libgl.so
lrwxrwxrwx 1 root root 10 2009-08-31 12:28 libgl.so -> libgl.so.1

-rwxr-xr-x 1 root root 618176 2009-08-31 12:28 libgl.so.185.18.36

same libglcore.so.1

lrwxrwxrwx 1 root root 22 2009-08-31 12:28 libglcore.so.1 -> libglcore.so.185.18.36
-rwxr-xr-x 1 root root 16118572 2009-08-31 12:28 libglcore.so.185.18.36

whats wrong glx extension ? mean incompatibility libglx.so library nvidia ? suggest workaround ?
