Dear all, Here is a longer set of experience to help track the dirty pointer.
Initial situation: both LVDS and VGA on when starting X. launching gnome-screensaver: fading on LVDS, not on VGA. xrandr --output LVDS --off --output VGA --auto xrandr -q (without it, as said before, it crahes) fading on VGA xrandr --output LVDS --auto fading on VGA, not on LVDS (no crash) xrandr -q fading on LVDS, not on VGA Regards, Sam
