Martin Konopka, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux REPLACE-WITH-BUG-NUMBER Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful. If reproducible, could you also 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-v3.13-rc7 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. Please let us know your results. Thank you for your understanding. ** Package changed: xserver-xorg-video-intel (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1257766 Title: can not reduce brightness on HP ZBook Status in “linux” package in Ubuntu: Incomplete Bug description: machine: HP ZBook 15 (Intel Core i7 4700MQ Haswell, NVIDIA Quadro K1100M 2GB, 1920 x 1080 display) I go to the settings/Brightness & Lock section. The button which should controll the screen brightness is on the right-hand side. I move it to the left-hand side but nothing happens. The screen brightness remains to be 100% (too much for me). The machine is running on the AC power cable. The machine uses an intel graphics driver. It contains also the NVidia card but that one is apparently inactive and the system did not offer me to install it.
