I just tried booting Ubuntu 6.10 (Edgy Eft) Knot 3 desktop cd (http://cdimage.ubuntu.com/releases/edgy/knot-3/edgy-desktop-i386.iso) on my Acer Aspire 1692WLMi and have the same problem. The LCD screen goes blank. The problem is solved by adding Option "MonitorLayout" "LVDS,AUTO" at the monitor section of xorg.conf. I attach the ouput of lshw command and /var/log/Xorg.0.log
