[Bug 698873] Re: Screen Brightness not working in Sony Vaio

 

** Description changed:

  Binary package hint: xorg
  
  I thought I already submitted this bug, but I can't find it  anywhere on
  my profile.
  
  The screen brightness buttons don't work in ubuntu 10.10.  I'm not sure
  what package this is in, but I would imagine it's in xorg.  Note though
  that when I unplug the machine, the screen brightness dims (unless I
  uncheck it in the power manager), and when I turn up and down the
  brightness nob in the power manager, it does go up and down, but the
  screen will not become brighter/dimmer when pressing the command keys to
  do so.  (So maybe it's just an issue with the key bindings?).
  
  I am running ubuntu 10.10, and it previously worked fine in ubuntu 10.04
