Vincas Dargis, as per https://www.asus.com/Notebooks/N551JM/HelpDesk_Download/ an update to your computer's buggy, insecure, and outdated BIOS is available (205). When you update to this following https://help.ubuntu.com/community/BIOSUpdate how does this improve the situation?
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. Also, you don't have to create a new report. It is most helpful that after the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command (not perform an apport-collect): sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on how this improves the situation. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your help. ** Description changed: - Hi, + Screen brightness fn keys don't work. - I've found solution for screen brightness keys issue in ask ubuntu [1], - which is simply to add "acpi_osi=" kernel argument. - - If troubleshooting is already done, solution discovered, could we have - some proper implementation in kernel itself, so user should not need to - fiddle with kernel arguments? - - [1] http://askubuntu.com/a/603980/99520 + WORKAROUND: Add kernel parameter: + acpi_osi= ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-31-generic 4.4.0-31.50 ProcVersionSignature: Ubuntu 4.4.0-31.50-generic 4.4.13 Uname: Linux 4.4.0-31-generic x86_64 NonfreeKernelModules: nvidia_uvm nvidia_drm nvidia_modeset nvidia ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC1: vincas 4675 F.... pulseaudio - /dev/snd/controlC0: vincas 4675 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC1: vincas 4675 F.... pulseaudio + /dev/snd/controlC0: vincas 4675 F.... pulseaudio Date: Mon Aug 1 16:20:41 2016 HibernationDevice: RESUME=UUID=8c5322e6-f871-4abf-b1e0-61b84f0aa4b4 InstallationDate: Installed on 2015-06-25 (402 days ago) InstallationMedia: Kubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150219.1) MachineType: ASUSTeK COMPUTER INC.
