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
