I've tested Alpha 6 live CD (without installation) on my system, but the same problem happens as before: when the desktop should appear, I can hear the welcome tune, but then the screen goes back to the screen. with the Ubuntu logo and the moving white line. Then again the welcome tune starts then it jumps back again and so on until it switch the laptop off.
The last version that ran perfectly was Alpha 4 with NO updates. If I let the update manager update my Alpha 4, then this problem starts. Btw with Alpha 4 all hardware was working: webcam, bluetooth, wifi, everything out of the box. That's why I bought this laptop. Thanks!!
