As per the automated request for further testing, I have downloaded the latest Oneiric Ocelot daily build (20110912) which uses a newer development kernel. The bug is still present. I have also noticed that while the proposed fix (see comment #9 above) does restore backlighting, but not after resuming from suspend. I have also noticed that OpenGL based applications that attempt to run in full screen cause the backlight to be deactivated. When these programs are shut down, the backlight remains off, and the default resolution is changed to that of the OpenGL program. I tested this with two different programs, Zsnes, and Gens, neither of which is available in the official repositories. These programs are also built for 32-bit systems, and were running on 64-bit using 32-bit compatibility libraries. At this point I am unsure as to whether this behavior is the result of the programs in question, or a result of the bug. I will be re-configuring the X server to use other drivers than i915 and test the results. I will also attempt to run OpenGL applications that are available in the official repositories, and built for 64-bit. I will post my findings here when I have more information.
