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. Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Tags removed: bios-outdated-0352 ** Tags added: latest-bios-0352 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.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.
