Thanks for the quick reply! I'm not technically disinclined to take these steps to further troubleshoot the issue, but am wary of undertaking steps this week that may result in being unable to "boot into the OS". Is this the only way to verify a fix? This is a primary development machine and a busy week here.

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.
