Is your machine even using the intel backlight device? You can test this by: # cd /sys/class/backlight/intel_backlight Then look at 'max_brightness' and try echoing a range of numbers from 0 to max_brightness into the brightness file and see if it changes the backlight. It's more than possible that your machine is simply using some other hardware to drive the backlight and that the integrated backlight controller is simply disabled. =2D-=20 keith.packard@intel.com --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIVAwUBTsf6fzYtFsjWk68qAQhIVQ/+LHiK5jMzmf1DfDMIChU42klsGSbBwlP3 eJ47W6UcnydeQxsdS+KNp0Kob039IXnA0arfYk+67DEl2hjUC08VaG86miHR5TTe n30xLfNaA3wRzG4+3b834/0ddxsTU9aPgT4Vh5A8YAfYg3MscffvgFfQO/bsMezx RxqfUr8z2t9W7nJaceSq1Bi3JXfA3xDxe8SsqBjQAxR/ppMsfTfqPsP43D+Mbqun YyAlW5aS9an0zxSu9XQxwv86aQln0GLnrhi0lcmR9gaobJ+BkCUmCLNwzP5poeMv Aph3PWa5LDbQaN5map2dXbEUZBFQi/SbUtP3W/lCwQN0fGqYrcDplWPi2mMCHWff CFjhYDXD/SkYaEDb+4mmL3p5XdUpblZLi0lcKqpeFWn+eLtP187q35SC04rE0ksf KkmUWixzO6ZFWhASVhb/oPqlyzP+5/xYjCdEa3DyvfGoBs5UfCjwU5xmnz0+guu+ xd9zfsa20uRYUhFxK9jgIcLKBb+GnrNpk0xQ/q8L5auiqv2j1pVcffvf/ZlW689Z yvgVbNlPZhDqHuQrrBr6fGcg8wwAeGtYnI4bJGFFp1IKnmhQEDbJXDyfJ4ygxfxJ B0rIoX/w/YOFA4ibt0r5s1PKPMMHrsdPRlXnfR0F+d4J7Ali5m2uk/suSDIvxNRd qVZDbn79Ya0= =cCjc -----END PGP SIGNATURE----- --=-=-=--
