There are three ports, two DisplayPorts and one VGA, only the initial
cold plugged port will work, and others will not work if you try to hot
swap, but the initial one remains working if you plug back.
And the system became really laggy when plugged DisplayPort, no matter
it's coldplugged or hot swap later.
Trying to hotplug on DisplayPort, getting following messages from
