Subject: linux-image-2.6-powerpc: Missing CONFIG_PMAC_BACKLIGHT_LEGACY breaks backlight control Package: linux-image-2.6-powerpc Version: 2.6.18+5 Severity: grave *** Please type your report below this line *** In the current debian kernel 2.6.18 the option CONFIG_PMAC_BACKLIGHT_LEGACY is not set. This option disables some PMU ioctls that won't be needed anymore due to the sysfs backlight interface. Unfortunately the current setting also disables IOC_GRAB_BACKLIGHT, that _is_ needed by any user space daemon that likes to control the LCD backlight. The kernel contains still code to read the backlight up/down keys and sets the backlight by its own. This ancient code fragment uses only 15 backlight steps (sysfs will support 127 or more) and will interfere with any user space program that likes to control the LCD backlight on its own. With the ioctl IOC_GRAB_BACKLIGHT the kernel code can be disabled so that it won't interfere anymore with user space actions on the backlight. This bug is at least grave because it will break system daemons like pbbbuttons, hal and any other that controls the backlight on powerpc. Please set the kernel option CONFIG_PMAC_BACKLIGHT_LEGACY in the official debian kernel.
