Hi, I've been the proud owner of a Lenovo W700ds dual-screen laptop which runs quite well under FreeBSD (8.3-STABLE atm.) There are some issues I haven't been able to solve despite hours and hours of googling. The most annoying issue are the backlights of the screens. I can adjust the backlight of the main screen using Fn+Home and Fn+End while in text mode but not while in X11 and I've not been able at all to control the backlight on the side screen. Are there any knobs I can try besides nvidia-settings (which only allows me to adjust brightness, contrast etc.) and the non-functional (under X11) Fn+Home and Fn+End keys? I've not been able to confgure X-windows for three screens (main + side panels + DVI output). Any ideas? This Thinkpad appears to have two audio cards: # cat /dev/sndstat FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64) Installed devices: pcm0: <HDA Conexant CX20561 (Hermosa) PCM #0 Analog> (play/rec) pcm1: <HDA Conexant CX20561 (Hermosa) PCM #1 Analog> (play/rec) default The speaker is on pcm1 (so I have hw.snd.default_unit=1 in sysctl.conf to make that one default) and the earphone jack is on pcm0. If I plug in the earphone, speaker sound stops but to get sound out of the earphone I have to explicitly use pcm0. Snd_hda is supposed to be able to re-route input and output pins but I wouldn't know where to start fiddling with GPIO pins of the codecs. Any help much appreciated. Thanks in advance for any help!
