Comment (by ttcoder):
Replying to [comment:4 korli]:
> Just a theory... If the buttons work with ACPI disabled, the reason
could be that by default the firmware handles brighness events itself.
When ACPI is enabled, the firmware would not handle events anymore, thus
leading to a "regression" for the user.
Just tried -- rebooted, disabled ACPI then proceeded with boot and... it
'''works'''! Good hint/intuition, thanks. Could get me off the hook some
day, so I don't need windows to setup the display on this laptop (an R61..
Not sure if this would be true also for this ticket's original poster, but
here it works... though of course as a side-effet I lose the "battery
indicator" in the deskbar).
