I'm running a little experiment and generally messing around with my laptop. My computer is a Uniwill M31EI. Intel ICH7 chipset. The main thing I would like to do is have a way to programatically find out what the current brightness and fan states are. If I could have some way of setting them, too, that would be a bonus. /proc/acpi/video/IGD/LCD/brightness says 'not supported' and the 'fan' directory lists no files. out of curiousity, I have tried writing a program that searches the first half-megabyte or so of /dev/mem and looks for changes (and no-changes) on demand so I could try and see if the brightness or fan states are in there somewhere. I may be doing something wrong, but as best as I can tell they are not. Is it possible to figure out a way of accessing such information without the aid of the manufacturer? I'm not afraid to get my hands dirty, if this requires disassembling things and such. Where should I be looking, how do developers find such information? Thanks in advance. - Pete - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
