Default Bug#569892: xbacklight: after having worked before, now just prints "No outputs have backlight property"

reassign 569892 linux-2.6
retitle 569892 [drm/i915] doesn't fall back to native backlight method without a platform driver
kthxbye

Not xbacklight's fault.

xserver-xorg-video-intel used to offer a few methods for changing the
backlight, defaulting to platform drivers providing
/sys/class/backlight/*. With KMS the i915 driver should probably
provide a fallback if there's no platform driver for backlight.

Thank you for the insight.
I can confirm this: I've searched for an older kernel to try one that
predates the introduction of KMS and found
linux-image-2.6.26-2-686_2.6.26-21lenny3_i386.deb.
I've installed and booted it: xbacklight (and the gnome power manager
brightness applet) work again.

I wonder wether #561241 will solve this one, too.
