Comment 65 for bug 415023

A possible workaround to avoid the flicker (at least in my case) is to disable kernel modesetting, that way g-p-m does not seem to get out of sync, although it is still buggy in that each brightness keypress is handeled twice, that is both by g-p-m and in hardware.

The main problem is making g-p-m not react to the brightness key presses. The MSI Wind apparently handles them in the BIOS while still passing through keypress events which are noticed and reacted upon by g-p-m. Adding the brightness_in_hardware setting to HAL is not a proper solution because the Intel xorg driver supports handling the backlight through xrandr which g-p-m prefers over HAL and HAL support will most likely be dropped from g-p-m once all other drivers support this through xrandr as well.

An please STOP spamming this bug with pointless and completely irrelevant comments, it makes the ubuntu bugtracker such a pain to use when one has to wade through dozens if not hundreds of posts to find some relevant information.
