Bug detailed description:
--------------------------
startx, then "pkill X", and restartX again. we will get a blank screen, from the output of "xrandr -q", we can see VGA is connected, but there is no VGA port on G45. I think maybe it is related to the issue of blank screen .

xrandr shows:
[root@x-g45a ~]# xrandr -q

btw,there are two output ports on g45,one is DVI-I, the other is HDMI.
the output of xrandr with UMS is as below:

HDMI-2 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 338mm x 270mm
   1280x1024      60.0*+   75.0     60.0*
   1152x864       75.0
   1024x768       75.0     60.0
   800x600        75.0     60.3

Although bug #21120 is in UMS, but root cause is the same, so mark it as duplicate.
thanks
