--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
The backlight is independent of the pipe, so both need to be turned off. Due to
hilarities with supporting all kernels and the kernel not always being in
control of the backlight, we need to turn off the backlight manually.

The question you should be asking is: why are we turning things off for a VT
switch?
