[Bug 1399823] Re: Backlight doesn't work on Samsung np730U3E-S01PL

2014-12-07 Thread Christopher M. Penalver
bademux, thank you for reporting this and helping make Ubuntu better.
Just to advise, in the future please do not compress/tar attachments as
it makes it harder for developers and triagers to help you.

Despite this, could you please test the latest upstream kernel available
from the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue.

If the test 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 bug is fixed in the mainline kernel, please 
add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested exactly 
shown as:
kernel-fixed-upstream-3.18-rc7

This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.
