Bug Description
after a update from linux-image-
It is quite impossible to change the backlight nor with the hotkeys or trough the sys-fs interface.
This is a real showstopper and should be fixed immediately as you can't read anything from the screen cause the screen is very dark. (Backlight is on but on the lowest level)

@Sebastian -- I think this is very likely duplicate of bug #314119, which was fixed by (and now duplicate of) bug#311716. Could you test the kernels at the URL below:
http:// people. ubuntu. com/~apw/ lp311716- intrepid/
The fixes for this will also very soon be in -proposed in version 2.6.27-11.23 so you could test it that way. Please see https:/ /wiki.ubuntu. com/Testing/ EnableProposed for documentation how to enable and use -proposed.
Either way please try and test and report back here. Thank you in advance!
