Public bug reported:
Running Intrepid Ibex (current as of 26 Oct 2008) on a T61 Thinkpad with
Intel gfx GM965/GL960.
Problem: When I use the brightness controls on the keyboard (Fn+Home or
Fn+End), the brightness does up or down, but with a lag of about 1-2
seconds per increment up or down. Also, each press increments 2 'ticks'.
Going from minimum brightness from 100% (or from maximum to minimum), it
takes 30+ seconds due to the extreme lag.
This ONLY occurs using the keyboard hotkeys.
Using the app from System>Preferences>Power Management and using the
slider bar labeled "Set Brightness To:" works properly.
This problem did not exist in Hardy, but WAS in Gutsy.
