myth12 ~ # ls -al /usr/lib/opengl/xorg-x11/extensions/libglx.so
-rwxr-xr-x 1 root root 334456 Jun 27 12:56
/usr/lib/opengl/xorg-x11/extensions/libglx.so
myth12 ~ # ls -al /usr/lib/xorg/modules/extensions/libglx.so
lrwxrwxrwx 1 root root 45 Jun 27 13:00
/usr/lib/xorg/modules/extensions/libglx.so ->
/usr/lib/opengl/xorg-x11/extensions/libglx.so
myth12 ~ #
