Title: Unable to adjust brightness Status in linux package in Ubuntu: Confirmed 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.
