According to this bug report, intel-virtual-output encounter some difficulties with xorg-server version 1.17.1:

david@david-ubuntu:~$ intel-virtual-output 
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
      after 20 requests (20 known processed) with 0 events remaining.

As reported by a user, downgrading to version 1.16 would solve the problem. How can I safely downgrade the xorg package?

You can downgrade your xserver-xorg to 1.16 in Ubuntu 14.04 by running

sudo apt-get install xserver-xorg-lts-utopic libqt5gui5 libgles1-mesa-lts-utopic libgles2-mesa-lts-utopic libgl1-mesa-glx-lts-utopic libgl1-mesa-glx-lts-utopic:i386 libglapi-mesa-lts-utopic:i386 libegl1-mesa-drivers-lts-utopic

You can check the version by dpkg -l | grep "ii xserver-xorg-core"

  • That installed xorg v1.16, but at the next rebbot lead the computer to a black screen before login, maybe due to my previously done configuration for bumblebee... – David Sep 20 '15 at 9:37
  • You will need to re-install all the nvidia stuff. I can't help with bumblebee. – Pilot6 Sep 20 '15 at 9:38
  • Thanks, now I'm trying, perhaps it is convenient to reinstall completely ubuntu and firstly downgrade. Have I to block somehow the xorg version to prevent an upgrade? I think I can mark as solved the answer after that. Thanks – David Sep 20 '15 at 9:42

    You do not need to block anything. The xorg major versions do not change on regular upgrades. They are in different packages. 3.16 is lts-utopic, 3.17 is lts-vivid. – Pilot6 Sep 20 '15 at 9:54
