[Bug 640020] Re: Screen flickers, brightness toggles

 

** Description changed:

  Binary package hint: xorg
  
  machine: MSI Wind U120
  System: Ubuntu 10.04 Lucid
  
  Using the Fn keys to decrease/increase screen brightness, the screen begins to flicker, while the screen brightness bar display toggles between two values. This fault occurs erratically, i.e. not always. Sometimes I can't even adjust the brightness at all!
  While the screen flickers, the cursor moves uncontinuously, making it hard to do anything. If I'm able to do a right mouseclick on anything that pops up a menu, the flickering stops.
  This bug apparently has been reported for older versions of Ubuntu, but is marked as fixed for Lucid. Obviously it's not!
