[Kernel-packages] [Bug 1391153] Re: Thnikpad X220 - brightness control doesn't work
Update - I just started 3.13.0-39-generic from Trusty (on which everything was OK). But now it doesn't work. I can control brightness before X is started, but when lighdm starts brightness control no longer works. IMHO this is rather related to X server, not kernel, what do you think? -- 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/1391153 Title: Thnikpad X220 - brightness control doesn't work Status in “linux” package in Ubuntu: Incomplete Bug description: After upgrading to Ubuntu 14.10 brightness control no longer works on Lenovo Thinkpad X220.

narel, the next step is to fully commit bisect from your prior working kernel to 3.16 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.

[Kernel-packages] [Bug 1391153] Re: Thnikpad X220 - brightness control doesn't work
narel, 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-rc5 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.

I've just updated BIOS: 8DET69WW (1.39 ) 07/18/2013 Unfortunately brightness control still doesn't work via hotkeys (echoing value to /sys still works). Is there any way to check/modify action performed by hotkeys? I see that they are correctly regognized by xev as XF86MonBrightnessUp and XF86MonBrightnessDown.

narel, as per http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x220 an update to your BIOS is available (1.39). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, then please mark this report Status Confirmed.
