Help! I just installed Fluent 6.1.22 on Red Hat 9. it all work fine until you try and open a graphics window, to, for example plot contorus or residuals. I get this error:

Error message from graphics function Show_Device_Info Server does not have a GLX extension.

Any help, please? I have run fluent on this machine befor without these problems.

Try running:

xdpyinfo

(or possibly xdpyinfo | more)

Does it mention GLX as an extension?

What about glxinfo?

Sounds like your x server is not configured correctly, so have a look at the log file for it (probably /var/log/XFree86.0.log) and the config file (/etc/X11/XF86config-4)
