Yes, fresh install using the Mageia 2 beta 1 netinstall ISO, I selected 
the LXDE desktop to keep the install size small.

Well if I press Ctrl-Alt-F2 after waiting 10-15 seconds after the screen 
goes into standby during boot, I still don't get the a video signal 
back. I can then press Ctrl-Alt-Del and the system will shut down 
cleanly so it's not frozen, it's only the video output that doesn't 
work with Mageia.
