Hello, i implemented an application using qt-opengl under Ubuntu. When I test the app in Ubuntu 9.10 32bit, terminal shows "Unrecognised opengl version". The display can no be updated, and shows wrongly. I think this is caused by some missed libs. After testing around, I could find the correct lib to install. Anyone knows the solution? Thanks in advance.

Well that could mean a lot of things...
It would be helpful if you tell us more about your GPU and drivers. Does the hardware-acceleration work in the other programs (ex. glxgears). You can also post here the outputs of glxinfo.
