Julien said: "the Alpha 1 is a snapshot of the actual development, with minimum tests. Expect others breakages until Alpha 2. However, you can easily test it
under virtualbox or qemu".
Buggy (as known black background, the panel appears in the middle of the screen, checking the CD fail, start menu not correctly translated, splash screen may fall-back to Ubuntu text one, istaller doesn't install correct restricted packages).
Anyway, if you want to test it go to downloads section and grab it while hot.
