EMC2 v. 2.5.0 crashing on startup

Hey guys,
I just installed the latest package of EMC (2.5.0) via the linuxcnc-install.sh on Ubuntu 10.04 Lucid Lynx.
That worked pretty well, i could even generate a config with the Stepconf Wizard and in the wizard i could run my stepper motors with this little testing program.
But everytime i try to run EMC you see it loading, but before the window is completely visible it crashes with this errormessage, wich does not tell me too much

Well, the errormessage i posted before was not the one from my config, but it happens with every config i try.
This is my file (please ignore the z-axis, its not ready yet)
I dont know if you need it but here is the error message form my config

I get "2.6.32-122-rtai"

Could it be something with the graphics card drivers? Thats my only idea

btw. thanks for the quick response

That both seems to work
I guess that means it is the graphics card?
My Graphics Chip is an Intel 82815

I ran "glxinfo | grep direct" and it said "direct rendering: No (LIBGL_ALWAYS_INDIRECT set)"

Thank you very much,
with the documentation i solved the problem, i still don't exactly know what it is,
but installing the software-only OpenGL package helped ( point 5.2 in the documentation if anyone has the same problem)
i can now start the program properly and run my steppers with it
