Using a G550 with mga_hal and recent CVS, if *from the console* I start a true dual head (different output on each screen), then VT switch back to the console, the console appears on both screens. Starting from a single head setup, the second head doesn't show the console on VT switch. Like Dmitry, running a single head config blanks the other screen. -- Dr. Andrew C.
