Hello. I downloaded the latest kernel 4.1.1 for the Trusty LTS that I am using and even there the behaviour is the same. Again the workarounds I previously mentioned still work. Now I'm not an expert but I really don't think this is a kernel bug at all because if the Xorg conf entry is there then the kernel seems to be perfectly capable of sending the requisite commands to the LCD firmware to adjust its brightness upon user hitting the hardware key. I don't have any pre-Saucy installations to test whether those versions automatically had the entry, or whether some change in the kernel or Xorg or elsewhere started requiring the existence of this conf file in order for the desired behaviour to be restored. So possibly you should be investigating why the Xorg conf file is no longer put in there by default by the installer or such... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1255428 Title: 8086:0116 [Lenovo IdeaPad Z570] LCD brightness control keys and widget do not work on Intel Graphics on Saucy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1255428/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Shriramana Sharma, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine 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. For example: kernel-fixed-upstream-3.15-rc1 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. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed.

Hello Christopher. I did the update just now and nothing has changed. Here's the output you asked for: $ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 45CN38WW 10/21/2011 BTW as I already mentioned, I wonder if you are looking for the problem in the wrong place. I filed this bug against the kernel since I did not know where exactly else to file it and the hardware hotkey is not working. But as I said, if I manually adjust the contents of /sys/class/backlight/intel_backlight/brightness the actual display brightness does change. The problem is only that I am not able to change the brightness via the keyboard hotkey as well as the power applet. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1255428 Title: 8086:0116 [Lenovo IdeaPad Z570] LCD brightness control keys and widget do not work on Intel Graphics on Saucy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1255428/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
