I think I'm seeing this too, xserver-xorg 1.4.1, -intel 2.2.0, on a Thinkpad X60.

When I work on the LVDS, the display is fine. When I switch to VGA and disable the LVDS, I get occasional jitters of the screen and sometimes (one every few days) the VGA output turns itself off. If I remove the VGA cable and blindly xrandr --auto, the LVDS turns back on but I can't enable VGA again.

My monitor appears to emit broken EDID, or the intel driver doesn't read it properly, so I need a custom modeline:

Modeline "1680x1050" 149.00 1680 1760 1944 2280 1050 1050 1052 1089

Is this the same issue, or should I file another bug? Can I contribute anything useful?
