I searched but I only found an error with different symptoms but the same log message: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1301398 As it claims that it was fixed in 3.15, I installed 3.16.0-37-generic from Utopic and voilà: It works without problems and error messages. So I am in a better position than Kamil in #28 but as I am even using the same model of notebook (different hardware configuration possible) we still do not know why it occurs.

However, if I unplug it and then replug it later, it is not detected anymore and the screen receives no signal. A way to get it back to work is to reboot or simply suspend the computer.
