Comment 138 for bug 568611

General info (nothing new)...

My backlight PPA at https://launchpad.net/~kamalmostafa/+archive/linux-kamal-mjgbacklight provides an experimental brightness control fix for Ubuntu Maverick (10.10) and Natty (11.04) systems with Intel i915 graphics processors (and possibly Radeon (untested)). The patches, primarily the work of Matthew Garrett, are still pending review upstream. Inclusion of these patches in the official Ubuntu kernels will likely occur only after the patches settle in the upstream kernel trees.

@everyone: Thanks very much for all the feedback and test results folks.

@jorgejhms, @Matias: There is no actively maintained solution for Ubuntu Lucid (10.04) -- my old "linux-kamal-i915bri" PPA for Lucid is stale and will no longer be maintained. I think its unlikely that any further work on this issue will occur for Lucid.

@Sohail: No, this bug is not the same issue as the Nvidia bug you referenced (but thanks for noting the similar problem).
