[Asus UL30VT] Backlight
Hi Christopher,
thanks for your continued help.
The command
echo 8 /sys/class/backlight/intel_backlight/brightness
does set the brightness to a very low value (basically completely black). This
was done with the acpi_backlight=vendor kernel parameter in use.

Hi,
I have now gone back and tested kernels back to 2.6.32, the kernel that was
used in Ubuntu when this laptop was released. It seems I remembered
incorrectly, backlight control has never worked properly on this laptop.
Backlight control did not work on any of the kernels I tested. I tested
RK, could you please test the latest mainline kernel via 3.18-rc6 and
advise to the results?

Hi,
I've tested the new 3.18 kernel
($ uname -a
Linux lina-UL30VT 3.18.0-031800rc4-generic #201411091835 SMP Sun Nov 9 23:36:36
UTC 2014 x86_64 x86_64 x86_64 GNU/Linux)
However, the bug persists. Backlight control does not work.
Furthermore, the touchpad control cannot be turned off with the
RK, the next step is to fully commit bisect from your prior working
release to Trusty in order to identify the last good kernel commit,
followed immediately by the first bad one. This will allow for a more
expedited analysis of the root cause of your issue. Could you please do
this following
