I was wrong about the way one tests for software rendering.
"direct rendering:no" means no DRI is available at all, qt4 gets

this case right already.

If DRI is avaliable, check the version string instead. If the work
is done by mesa, (software rendering library) then
it is better not to use it because it will be slower than any alternative.
