Hi. The subject says it all. As a blind user, I like to turn off the backlight of my monitor to save power. This can save up to 30% of battery lifetime, which is a quite significant number. However, it appears that I have to figure out how to do this on every new laptop I get (agreed, thats not that often, but still). I wonder if we should make an effort to collect know-how like this in some script which would make it easier for some of us at least on commonly-known models. To that end, I have started to write such a script for my current laptop model, a MacBooAir4,1. If you do something similar, maybe we could join forces to get at least something that works on a few model/brands out of the box. Detecting brands/models seems possible through certain files in /sys these days. If you have found out how to turn display (and possibly even keyboard) backlight off on your model, consider letting me know how you do it exactly. I know that there are certain tools for X11 to do this generically, but this is not as interesting to some of us as a generic, console-compatible solution would be methinks. If we can work out how to detect your brand of laptop automatically I would be happy to integrate whatever needs to be done for your laptop into the script I am currently developing. P.S.: This is not only a power-save feature but actually also a security-feature. It nicely prevents someone sneaking up on you and reading stuff off your monitor while you are not noticing. -- CYa, ⡍⠁⠗⠊⠕ | Debian Developer <URL:http://debian.org/> .''`. | Get my public key via finger mlang/key@db.debian.org : :' : | 1024D/7FC1A0854909BCCDBE6C102DDFFC022A6B113E44 `. `' `- <URL:http://delysid.org/> <URL:http://www.staff.tugraz.at/mlang/>
