I'm trying to start xvfb on CentOS6. But soon after I type a command to start xvfb, I faced following error.
(EE) AIGLX error: swrast exports no DRI extension
(EE) GLX: could not load software renderer
The command I typed is here:
Xvfb :1 -screen 0 1280x1280x24 &
Does anyone know the cause of this error?
