It's the #define in nv_backlight.c. > If its the former, then is it safe to play with the value or is this > best left to you guys? You can play around with it, it's likely a larger value, but you're on your own there. > Yes, I had been playing with this.

I don't know wether your distro already uses udev. > [EMAIL PROTECTED]:/dev$ sudo fblevel 0 > ioctl PMU_IOC_SET_BACKLIGHT: Inappropriate ioctl for device Obviously it can't work. If your Mac doesn't have a PMU, as I suspect, you have an SMU. In that case, you have to use the brightness property in /sys/class/backlight/*. You can "echo -n" values from 0 to 127 (as stated in the max_brightness property) into it. Something like this should work, altough I'm unable to test it right now: echo -n 50 > /sys/class/backlight/nvidiabl0/brightness Greets, Michael -- Gentoo Linux developer, http://hansmi.ch/, http://forkbomb.ch/
