Title:
No X on boot with external monitor connected
Status in xorg package in Ubuntu:
Confirmed
Bug description:
When booting from today's (201610907) daily yakkety livecd with an
external display attached X does not start.
If the external monitor is attached after X has started I can boot to
the desktop using only using the laptop's LCD (ThinkPad x230, intel
graphics). The attaching a 1920x1080 LCD via miniDP extends the
desktop but windows moved around produce a trail of windows that
persist even after the window is closed.
This is a regression from Xenial.
