Public bug reported:
fresh install of Hardy beta on an IBM TP R51. display
contrast/brightness keys function improperly. specifically, attempting
to lower contrast via fn+end results in OSD applet and hardware lowering
of contrast - yay! attempting to raise contrast via fn+home results in
only hardware raising of contrast - very 'not'-yay!) the applet never
seems to see the keypress or read the current hardware brightness value.
attempting to again lower the contrast seems to result in the setting of
the hardware brightness level to whatever the previous 'low' value was.
in other words if you lower contrast all the way down, then raise
contrast all the way up then simply lower the contrast again by one
level, the actual result is that the contrast reverts to the lowest
level possible. This is a change from the entire hardy alpha series
which seemed to function properly. additionally, if I force compiz on I
notice that I no longer get the compiz style contrast OSD, its always
the regular non-compiz OSD. hope this rambling report makes sense!
