[Kernel-packages] [Bug 1392101] Re: Brightness controls not working on intel igfx
Martin H, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested exactly shown as: kernel-fixed-upstream-3.18-rc4 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: asus brightness display intel laptop ** Tags added: latest-bios-210 ** Changed in: linux (Ubuntu) Importance: Undecided = Medium ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete ** Tags added: regression-release -- 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/1392101 Title: Brightness controls not working on intel igfx Status in “linux” package in Ubuntu: Incomplete Bug description: Brightness controls not working for me in Vivid Vervet as of 1-2 weeks ago.

Martin H, the next step is to fully commit bisect from kernel 3.16 to 3.18-rc4 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.

I'm not so certian it is a kernel error now after some digging deeper.

On the Utopic iso boot, running kernel 3.16.0-23-generic (according to uname -a), the brightness controls function absolutely fine. On the Vivid iso boot, the brightness controls no longer work. Booting my machine from the same kernel version as what was working on the iso, 3.16.0-23, the controls also still don't work.
