The chosen rate is different in these xrandr output, 59.9 when working,
while 60.0 when not working. Maybe your monitor doesn't like 60.0.
Can you try:
1) plugin the VGA cable so that X works
2) changing the rate from 59.9 to 60.0 with xrandr --rate
That said, it looks like having the VGA output detected with preferred
rate = 59.9 would cause the DVI chosen rate to change from 60 and 59.9.
