Re: Chromium GLX problem at the slavenode: problem still there after fixing GLX

Okay, quick question.  Can you run (and see) glxgears on every display
involved?  I get the feeling that you don't have a complete setup on
your cluster.

If the GLX extension is missing on any of your displays, you will have
trouble doing any OpenGL, let alone Chromium.

Being root won't matter one way or the other.
