Kernel version 2.6.11 is out now, and has extra ACPI support for the LCD. This is great news, as it's the last major power-management thing I haven't been able to get working on my notebook.


I've built the new kernel, and I have a set of extra directories under /proc/acpi/video where I can see items such as LCD brightness, however I don't know how to control this, nor can I find the place where I could power off & power on the display.

I had half expected it to show up when running "sysctl -a", but it does not.



Does anyone have any information on how to use this new functionality?

"...for example on PDAs..." might be an answer?!
