Bug Description
Cannot adjust the brightness in a Acer Aspire E1-570-6889.
The brightness key works and the brightness configuracion in the system configuration allows to adjust the brightness but the display does nothing, it is always at full brightness.
I may try some things esporadically since it is not my laptop, but I may take a long time to try them :-(.
Thanks.

Ivan Baldo, thank you for reporting this and helping make Ubuntu better. 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/KernelMainl ineBuilds ? 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 by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: fixed-upstream fixed-upstream- 3.XY-rcZ
kernel-
kernel-
Where XY and Z are numbers corresponding to the kernel version.
If the mainline kernel does not fix this bug, please add the following tags: bug-exists- upstream bug-exists- upstream- 3.XY-rcZ
kernel-
kernel-
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.
