Do you have an external monitor attached to the dock? If so, how do you have the screens configured when docked?

Which brightness controls are you using? The hardware keys or the software slider?

If you use the hardware keys, does the OSD show any changes after you undock but those changes are not reflected in actual brightness adjustment?

If you adjust the brightness in any manner, do the values of brightness/actual_brightness in /sys/class/backlight/acpi_video0 and/or /sys/class/backlight/intel_backlight change? If so, which is changed on 3.12 and which is changed on 3.13?
