Thank you for reporting this bug. That was certainly an interesting behaviour. Could you attach the output of `lspci -vvnn` as well? Does anything change if you move /etc/X11/xorg.conf to a different name and restart? (so that there is no xorg.conf when you start up, there will be a new minimal one created.)

Also, what is your monitor setup? Is this a laptop? Is there an external monitor connected using DVI? If this is not a laptop, you can try the Ignore LVDS Quirk on https:/ /wiki.ubuntu. com/X/Quirks# Ignore% 20LVDS% 20Output% 20Quirk .
