Leonyd, regarding only the NP-R540-JS05RU, because Samsung does not reveal what the latest BIOS is for this model, could you please download the latest firmware software as per http://www.samsung.com/ru/support/model/NP-R540-JS05RU-downloads, and advise if a BIOS update is available? If so, when you update to this, does it change anything? If not, 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
Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Thank you for your understanding. ** Summary changed: - Samsung R540 brightness not working + [Samsung NP-R540-JS05RU] Brightness not working -- 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/956274 Title: [Samsung NP-R540-JS05RU] Brightness not working Status in The Linux Kernel: Incomplete Status in “linux” package in Ubuntu: Incomplete Bug description: Does not change the screen brightness on Samsung R540, Samsung NC110 When using the charger is always the maximum (or near) the brightness when running on battery is close to the minimum Ubuntu 12.04 beta updated from 11.10 i386 had a similar problem on ubuntu 11.10 --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
