--- Comment #23 from Xavier Bachelot <xavier at bachelot.org> ---
Plugging an external monitor is an interesting bit.
Could you please post a dump of the registers both when using only LVDS and
when using LVDS and VGA. Comparing the 2 might give some insight on what's
wrong.

Another thing to try would be to use Option "ModeSwitchMethod" "legacy" and see
if that helps. Please provide the regs dump for this too.

In order to build the registers dumper tool, add --enable-viaregtool to the
configure script. Then sudo /usr/sbin/via_regs_dump -dpm
