+The command chvt N makes /dev/ttyN the foreground terminal.
+  sudo chvt 1
+chvt 1 : console\\
+chvt 7 : X11
+===== Run Xwindow =====
+=== 0. Create a new config file ===
+  sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old
+  sudo vi /etc/X11/xorg.conf
+=== 1. And then, add following lines in "/etc/X11/xorg.conf" file. ===
+<code>
+Section "Device"
+    Identifier    "C fbdev"
+    Driver        "fbdev"
+    Option        "fbdev" "/dev/fb2"
