ubuntu 14.10 x11vnc very slow.

[peterwillcn2]

sudo apt-get install x11vnc
sudo x11vnc -xkb -forever -auth /var/run/lightdm/root/:0 -display :0 -rfbport 5900 -bg -o /var/log/x11vnc.log
sudo mkdir /etc/x11vnc/
sudo x11vnc -storepasswd /etc/x11vnc/passwd
sudo x11vnc -xkb -forever -auth /var/run/lightdm/root/:0 -display :0 -rfbauth /etc/x11vnc/passwd -rfbport 5900 -bg -o /var/log/x11vnc.log -geometry 1280x800


Ubuntu 14.10 don't connect the lcd monitor open x11vnc display speed very slow, But the first turn on the monitor local after landing, then open the VNC client display speed quickly.why?
