I found that this bug is related with Bug #22985 (So we can mark this one as duplicated). The problem is solved by adding
Option "MonitorLayout" "LVDS,AUTO" at the monitor section of xorg.conf. I hope this could be fixed in the next version !!!! -- Ubuntu Edgy Knot 2 live CD doesn't work on Acer Aspire 1694WLMi https://launchpad.net/bugs/59638 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
