            Bug ID: 368221
           Summary: Unable to adjust display brightness on Dell laptop,
                    powerdevil messages in journalctl
           Product: Powerdevil
           Version: 5.7.3
          Platform: Kubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: plasma-devel at kde.org
          Reporter: jamiesexton35 at gmail.com

This seems to be a bug with either the Powerdevil configuration but looks
related to the Xorg driver, I had previously added this but should have
reported properly instead of just on the ubuntu bugtracker
https://bugs.launchpad.net/bugs/1503168. I haven't tried that fix yet with the
latest Manjaro but it does also apply as well with both Kubuntu 16.10 and
Manjaro with all updates including the Intel DRM nightly drivers from git. This
seems to affect multiple types of Dell laptops also including the Studio 1737
and N7010 (both about 10 years old) and both with integrated Intel HD graphics.
The Kubuntu install is since Alpha release, and the Manjaro install since 8/15
and is running 4.8.0-rc4-mainline as well. Appears the issue has resurfaced
since the KDE 5.x branch. Will add additional bug report from Kubuntu 16.10 as
well for secondary verification and information reporting

Reproducible: Always

Steps to Reproduce:
1.Use the function keys to adjust brightness
2.Watch the brightness bar go from none to full and back

Actual Results:  
End result, no change in display brightness but does log some journalctl error
messages when checking with `journalctl -xe --no-pager|grep -C10 bright`

Expected Results:  
screen backlight brightness should have changed
