Hi,

I am new to OSG so be gentle. Many of my users want to run their gui on a 
remote server through VNC, however, when I run the osgviewer cow.osg over vnc 
nothing gets rendered and I get lots of errors echoed to the terminal such as:

Got an X11ErrorHandling call display=0x643b30 event=0x4084f7c0
GLXBadRenderRequest
Major opcode: 148
Minor opcode: 1
Error code: 157
Request serial: 1620
Current serial: 1621
 ResourceID: 44

Even the very simple example in the quick start guide fails to render. glxgears 
runs fine so I know I can get a glx context. Actually osgviewer glsl_simple.osg 
renders its shapes but gives the following errors:

VERTEX glCompileShader "" FAILED
FRAGMENT glCompileShader "" FAILED
glLinkProgram "" FAILED
FRAGMENT glCompileShader "" FAILED
VERTEX glCompileShader "" FAILED
glLinkProgram "" FAILED

Is using OSG over VNC just a bad idea or is there some flag(s) I need to toggle 
to turn off some incompatible rendering feature?

Thank you!

Cheers,
Harry
