I believe my problem is now due to a bug in the 965 intel graphics driver. I grabbed the following updated driver from the below link and it didn't fix my problem. http://people.ubuntu.com/~bryce/Uploads/xserver-xorg-video-intel_2.2.1-1ubuntu6_i386.deb. I know the ubuntu7 driver is going to hit the repos soon, so hopefully that fixes my problem.
However, I have found a workaround. If I switch to 1280 x 768 then switch back to 1280 x 800, the backlight works. -- Backlight on laptop not working https://bugs.launchpad.net/bugs/203720 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
