QtQuick 2.0 example -> Could not initialize GLX (SOLVED)

[borut123]

I've just installed Qt 5.0 beta 2 with installer, created a basic example with:
File -> New file or project -> Applications -> QtQuick 2.0 Application, and tried to run it.

I get "Could not initialize GLX. The program has unexpectedly finished." when I try to run it.

Any idea what should I do to make it work?

Sorry, didn't notice till now that driver for my graphics card does not work correctly under Ubuntu 12.10
