Hi Keith, I had a chance to test your patches this weekend: drm: record monitor status in output_poll_execute drm: Set connector DPMS status to ON in drm_crtc_helper_set_config cherry picked from ickle's repo on top of Linus' git 0f639a3c5ca6 ("Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6"). Unfortunately, they do not correct my laptop backlight issue (fdo bugzilla #31803): the panel still dims whenever the lid is opened. -- Nick Bowler, Elliptic Technologies (http://www.elliptictech.com/)
