Notebook LCD broken, using VNC4

The LCD of my IBM X21 has become worse for quite a few days now, it doesn’t display the correct colors – black as red and white as cyan, etc, that’s horribe to the eyes. Until a new one arrive (the IBM X40, yay) tonight, I am using VNC4 on another desktop computer to use the X desktop. Strangely I can’t make the VGA output work after around the time that I upgraded to the 2.6 series kernel. I’m happy with VNC4 so far, the only problem is when I press Ctrl-space to switch to input Chinese, the keystrokes are captured by the host computer instead of the desktop being connected.
