Hello,

On my laptop, the display backlight is reported this:

See this screenshot: http://i.imgur.com/mP0H6hX.png

Now I am confused. Does this mean that my actual display brightness is 4W or 2W and this is only a displaying error of PowerTOP?

If the latter applies, can this be fixed so that PowerTOP only recognises one display?

I think it is related to the fact that I have two entries in /sys/class/backlight
 
lrwxrwxrwx 1 root root 0 2014-04-03 07:15:06.796659660 +0200 intel_backlight -> ../../devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/intel_backlight 
lrwxrwxrwx 1 root root 0 2014-04-03 07:15:06.796659660 +0200 acpi_video0 -> ../../devices/pci0000:00/0000:00:02.0/backlight/acpi_video0

Any help would be appreciated!

Tom
