I have some new findings, it looks like just the X-window and gnome panel don't
stay at the right place.

1. xinit& gnome-session&  --->  default extension mode(HDMI right-of eDP),I got
a screenshot gnome-session_default.png

2. xrandr --output HDMI1 --left-of eDP1  ---> extension mode HDMI left-of
eDP,mouse can slide from HDMI right to eDP, but X-window and gnome panel still
stay on eDP monitor. Screenshot HDMI1_leftof_eDP1_1.png

3. xrandr --output eDP1 --same-as HDMI1 --auto

4. xrandr --output HDMI1 --left-of eDP1
This operation will cause a warning like this:
Window manager warning: CurrentTime used to choose focus window; focus window
may not be correct.
Window manager warning: Got a request to focus 0x400022 (root at x-hsw) with a
timestamp of 0.  This shouldn't happen!

Extension mode HDMI left-of eDP,mouse can slide from HDMI right to eDP, X
window shows on HDMI monitor,but gnome panel stays on eDP monitor. Screenshot

All of the three pictures, left side is eDP,right side is HDMI.
