** Description changed:

  Binary package hint: gnome-power-manager
  
+ Problem:
+ The state of the numlock key affects how the brightness switching keys work.  
The OCD display does not display.  On some systems (e.g. Thinkpad 61's), it 
also prevents brightness from changing.  This seems to be a new behavior in 
Intrepid, and not reproducible on Hardy
+ 
+ A further issue on Thinkpad T61's is that the numlock key does not
+ signal toggle off properly.  This can be seen in xkbwatch, which shows
+ that some modifiers are not getting turned off when numlock is toggled
+ off.
+ 
+ Original Report:
  [regression from 8.04]
  
  I'm not sure about the root cause of this yet, but starting here.
  
  Pressing the brightness up/down keys on my ThinkPad T61 no longer
  changes the brightness of the LCD backlight.  This worked fine in 8.04,
  and at some point in Intrepid as well.
  
  When I press the brightness-up key, I see two ACPI events:
  video LCD0 00000086 00000000
  ibm/hotkey HKEY 00000080 0000501
  
  brightness-down is similar:
  video LCD0 00000087 00000000
  ibm/hotkey HKEY 00000080 0000501
  
  In xev, I see KeyPress and KeyRelease events forXF86MonBrightnessUp and
  XF86MonBrightnessDown, respectively.
  
  However, the backlight is not actually changed, and gnome-power-manager
  does not display the brightness level OSD (both of which worked in 8.04)
  
  WORKAROUND: gconftool-2 --set --type bool
  /desktop/gnome/peripherals/keyboard/host-perseus/0/numlock_on false
