I've tested the kernel suggested by Andy in comment #5 and the brightness started working again for me. Hotkeys are working also.
My problem was that after the update of the kernel from 2.6.27-10-generic to 2.6.27-11-generic (using proposed updates) the brightness on my laptop was not changeable. To be specific, when I upgraded to 2.6.27-11-generic, the brightness was not changeable using the hotkeys, /proc/..., /sys/... or even the scroll bar in the power applet directly. Using the hotkeys the UI with the progress bar seemed to hang for one second each time a change was made but with no effect. I have a Thinkpad T61 using the 32bit version of Intrepid Ibex 8.10. Now everything is fine! Thanks Andy for packages easy to test. May I suggest pushing this new kernel to intrepid-proposed? -- The slider brightness Applet has value inverted after the last update (2.6.27-11) https://bugs.launchpad.net/bugs/311716 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
