cursor disable in X11
摘自:http://www.noah.org/wiki/cursor_disable_in_X11
When working with touch-screen interfaces or embedded systems you often don't want or need the mouse cursor. Most of the information I found about this specific topic described people either trying to use `xsetroot` or loading a cursor theme with all the cursors set to transparent. The following is, I believe, the correct solution.
Simply pass the nocursor option to the X server when you start it. There are a million ways to start X-Windows. I will list four variations. When using `startx` or `xinitrc` you can put these options in .xinitrc.
Xorg -nocursor
X -nocursor
xinit -- -nocursor
startx -- -nocursor
