Chromium GLX problem solved

Sean,

Thank you for your advice. I finally solved the GLX problem by reinstalling
NVidia driver at all my slave nodes. It appears that even i could run
glxinfo and glxgears sucessuflly, I still need to reinstall Nvidia driver in
order to run Chromim. Now, i finally can run a tiled display application!!
