Mark Reeves, thank you for reporting this and helping make Ubuntu better. As per https://downloadcenter.intel.com/product/83255 an update to your computer's buggy and outdated BIOS is available (0352). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
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, if the problem is still reproducible: 1) Please provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) If the issue is still reproducible, please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-0352 ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1522139 Title: Unable to adjust brightness Status in linux package in Ubuntu: Incomplete Bug description: I have an Intel NUC that's otherwise running Ubuntu 15.10 great! It's hooked up to a ViewSonic monitor via mini-DV / DVI. The brightness controls are disabled on the monitor. xbacklight does nothing. And I don't have the Brightness slider in Brightness & Lock. I've been poking around, and have seen where to create a file in xorg.conf.d. The problem is, I have an empty /sys/class/backlight dir. Per the following, I'm submitting a support ticket: https://askubuntu.com/questions/577539/dell-chromebook-11-unable-to- set-backlight-and-sys-class-backlight-folder-is/578497#578497 I'd like to be able to increase the brightness on my screen.
