if its running it means glx is available. if glx is not available it will
complain. ensure that the qt libs find the nvidia opengl libs and not the
mesa ones (ldd on libqt-mt.so will show which libs its linking to)

qt examples are fairly simple examples, they won't show much difference
between software driven or hardware driven opengl.
