I couldn't get the VESA/MESA stuff working the other night, so went back 
to fglrx, which is what the Fedora installer chose for my machine.

I keep my update rates quite modest, and I can support multiple wxGUI 
FFT sinks on the same machine.  I'm running two different applications
  24 x 7 that have both Waterfall and FFT sinks, and my machine is only 
lightly loaded.  But I keep the update rates down to 5Hz or so.

Well, the qtGUI stuff is being worked on at the moment, and it should 
have much better performance, and provided it can give a similar
  amount of user-friendly stuff, perhaps at some point, we let the 
wxGUI stuff die.  Unless some brave soul wants to seriously work it over
  and make it a better performer, and eradicate the openGL edge cases 
that it keeps tripping over.
