Laptop screen stops working when HDMI screen is connected at boot

[Volodya]

This problem is new with 14.10, did not exist with 14.04

What i do to reproduce:

Turn laptop off
Connect a screen via HDMI
Turn computer on

What happens:

Laptop screen stops working as soon as the OS begins to boot
Once i login, it's clear that the OS thinks that the screen is working, since i can move my mouse into the area of that screen and move it around there. I can drag windows there and if i can grab them afterwards, i can move them back into the visible HDMI screen.
Disconnecting HDMI screen does *not* turn on the Laptop screen
The only way to get laptop screen to work is to boot and login without HDMI and connect it only afterwards.

What i expect to happen:

When booting with two screens, both should work with the settings in place.

I have intel 4400 (I think is also 3rd gen) and for me works fine. It seems to be a driver issue

[Volodya (volodya)]

It seems to have been fixed. Sorry i've forgotten to post here.
