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!
