Hi all, Sorry to revive an old topic from 3-4 weeks ago, but I just got my X61 this past week and so I missed my chance to chime in. And, as far as I can tell, Ben ended with "I'm pretty lost by now". Was a decent solution ever found? If not, where can I code to help? :) In my tests, the only way I've been able to get reliable backlight control is to blacklist "video.ko" and use "thinkpad_acpi brightness_enable=0". Then, the "intel" X driver handles it: $ xrandr --properties ... BACKLIGHT_CONTROL: legacy supported: native legacy combination kernel BACKLIGHT: 127 (0x0000007f) range: (0,255) and "xbacklight" gives me excellent control, with at least 100 discernible levels from 0-100%. Unfortunately, that's independent of the hotkeys and gnome-power-manager knows nothing about it. I suppose I could fix the hotkeys with acpid handlers if necessary. With "video.ko" loaded, the intel driver uses the "kernel" method instead, which I guess is why xbacklight doesn't work well in that case. I haven't tried overriding that. (Kernel 2.6.24, X intel driver 2.2.0) -jim ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
