Mark Reeves, it's not imperative you test this week, as this would be at your convenience.

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.

[Kernel-packages] [Bug 1522139] Re: Unable to adjust brightness
Mark Reeves, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results.

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 As per https://downloadcenter.intel.com/product/83255 an update to your computer's buggy and outdated BIOS is available (0352).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.

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.
