Hi Paul,

I just looked at olpc-kbdshim the olpc-brightness for how we adjust the 
brightness on the XO. Looks like we simply echo the values to the files 
like '/sys/class/backlight/dcon-bl/brightness'. I wonder what the 
generic solution is for that (Sugar on other devices).

 From a quick test, I have the following files on my T61: 
/sys/class/backlight/intel_backlight/max_brightness and 
/sys/class/backlight/intel_backlight/actual_brightness which change 
accordingly when adjusting the brightness. But I guess there is a 
generic tool for doing that...?

/me should probably have a look what GNOME is doing...

Regards,
    Simon
