Christopher, why did your scripts inspect this bug? It was marked as a duplicate of another bug and I cannot see any good reason for removing the duplicate status. I am putting the duplicate back, so that this bug falls off the visibility again, and the stronger bug wins. Please inspect your scripts, I believe they are incorrect. Thanks. ** This bug has been marked a duplicate of bug 1098216 Regression in brightness control on Lenovo Thinkpad X230 (+tablet) and X1 Carbon -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1156477 Title: laptop brightness keys regression Status in “linux” package in Ubuntu: Incomplete Bug description: In 12.04 LTS and 12.10, the fn+f8 and fn+f9 keys properly adjusted my Thinkpad T530's display brightness perfectly. I upgraded to Raring on Mar 17, and the brightness keys no longer work. The indicator appears but the slider does not slide and the screen brightness does not change. The brightness slider on the brightness and lock control panel feels like it has lost granularity -- but I cannot recall the exact behavior of the older slider.
