Unrecognized Opengl Version

[stella1016]

I am running my application (using qt opengl) in Ubuntu 9.10 32bit. It works fine in any OpenSuse. But for Ubuntu 9.10, the part which is using opengl is frozen, and terminal tells: Unrecognized Opengl Version.

I don't know the reason for that. Any library missing? I am running on VM, but it also happens in local machine.
Help!

I checked the version of my opengl on both machine. Whether 2.1 is too high for my application, or there is conflicts with sth else?

OpenSUSE 11.0 32bit:
server glx version string: 1.2
client glx version string: 1.4
OpenGL version string: 1.4 (2.1 Mesa 7.0.3)
