Created attachment 22559 [details] [review] this patch will resolve the problem. After testing ,this patch can resolve the problem by avoiding to modify bit 24 and 25, but it is strang why bit 24 and 25 of VGA will disturb LVDS. So In order not to generate other regressions I will manage to find the exact information before I commit the patch.
