can someone help me fix this please.

I can't help you with the problem, but I do know that the moderators don't appreciate posting the same thing twice in a short amount of time.

Also, just putting "help" in the title isn't very descriptive of the problem and some people won't even look at it.

A better title might have been :
Help..Xlib: extension "GLX" missing on display ":0.0".

good luck...
