I did not mean to say that ubuntu automatically changes resolution to
external display. But when an external display is connected, and the
command

xrandr -q

is runned, the system will find the external screen and change to the
resolution last used with this external screen. At least that is what
my system does and I haven't done anything to make it do so. I'm not
so sure my bug is unrelated in the fact that the system doesn't
totally crash, but just shows me two blank screens which i cannot do
anything about other than a hard reboot.
