ahmet yıldırım, thank you for reporting this and helping make Ubuntu better. As per http://h20564.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=5071172&swLangOid=8&swEnvOid=4060 an update to your computer's buggy and outdated BIOS is available (F.50). 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, and the information above is provided, then please mark this report Status New. Thank you for your understanding. ** Tags added: bios-outdated-f.50 ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1419689 Title: Screen bright change can not be controlled via Fn keys Status in xorg package in Ubuntu: Incomplete Bug description: Ubuntu 14.04 with the driver NVIDIA 346.35 does not work for Monitor bright option with Fn keys.
