Pekorius Nedas, because Samsung does not easily reveal what the latest BIOS is for this model, could you please download the latest firmware software as per http://www.samsung.com/lv/support/model/NP300V5Z-S01EE-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
Thank you for your understanding. ** Summary changed: - Samsung 300V5Z Backlight/Brightness controls + [Samsung NP300V5Z-S01EE] Backlight/Brightness controls -- 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/973321 Title: [Samsung NP300V5Z-S01EE] Backlight/Brightness controls Status in “linux” package in Ubuntu: Incomplete Bug description: Unable to change screen backlight level Brightness function keys work only from 100% to around 85% and back to 100%, looks like it only moves one step down. but brightness can be modified directly on display settings, so the bug is only on the function keys.
