I have ported the proposed new backlight control mechanism[1] -- primarily the work of Matthew Garrett -- to Ubuntu Maverick (2.6.35 kernel). Many thanks to Matthew for his fine work!
An EXPERIMENTAL Maverick kernel PPA which includes the fix (plus some Dell-specific glue) is available. I have tested this on a Dell Studio 1558 only, but it may fix the brightness controls for other laptop brands and models also. See the IMPORTANT installation notes on the PPA page for more details: Maverick PPA: https://launchpad.net/~kamalmostafa/+archive/linux-kamal- mjgbacklight Feedback to this bug report will be appreciated. Developers: The source patches are also available for inspection[2]. Be aware that Matthew's patches were slightly modified from their original form by me, for the 2.6.35 backport. I do not intend to backport this work to Ubuntu Lucid at this time.
