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
