I've flashed new BIOS to 205 from Asus website: vincas@vinco:~$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date N551JM.205 02/13/2015
But sadly it did not helped. Though it is strange that dmidecode shows 2015 as release year, while on website they say it is updated at 2016. ** 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/1608526 Title: Asus N551JM screen brightness keys fn+F5/F6 don't work unless using kernel parameter acpi_osi= To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1608526/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
