            Bug ID: 324258
           Summary: erratic screen brightness with power management
                    enabled.
    Classification: Unclassified
           Product: kde
           Version: 4.11.0
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED

When the laptop is running on battery, sometimes it just starts to jump from
100% brighness down to ~45% then back to 100% and back to ~45%.

This happens so fast that the screen flickers. Only way to stop this is to
disable power management or try to connect the charger and keep it or
disconnect it again.

Sometimes this just triggers when you change the brightness when on battery or
just when disconnecting the charger. Or sometimes just at boot.

Reproducible: Sometimes
