I experience the same issue with an Asus M2400N and the intel 855gm
chipset. A solution for half of the problem is to switch to a VT with
Alt-F1 and back with Alt-F7. Then the garbage on the LCD is gone but the
external video signal is switched off again.
Another workaround is to start another X session with gdmflexiserver
after switching to LCD+External. The new session should be displayed
well on both screens. When you switch back, the garbage is gone and
external output is off again. YMMV.
