Downgrade xorg-server

  • 772

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?

14.04

    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"
