1. Problem

The OS can't detect the qxl video driver. The display resolution can't be changed not to mention adjust automatically.

Try to solve it by kill X,then reconfigure it. 

init 3

after relogin 

X -configure

It keep complains

2. Solution

  1. Turn off Xserver used 

    sudo init 3

  2. Remove xserver-xorg-core 

    sudo apt-get remove  xserver-xorg-core -y

  3. Install the driver or so 

    sudo apt-get install  spice-vdagent gdm xserver-xorg-video-qxl-hwe-16.04

  4. Create the xorg.conf we needed 

    sudo X -configure
sudo cp ./xorg.conf.new /etc/X11/xorg.conf

  5. Get X Back 

    sudo apt-get install   xserver-xorg-core xserver-xorg-input-all -y

  6. Make sure spice-vdagent start automatically 

    sudo systemctl enable spice-vdagentd
sudo systemctl start spice-vdagentd

  7. Time to cross your fingers 

    sudo init 5

If everything goes smoothly, your screen resolution will change automatically.
