Hi all:

   I have some question when using RandR1.2.
I'm using RandR EXA to do the rotate(Xorg1.5.2), it seems when the screen
rotate, the Xserver will first redraw the on screen,then use composite to do
the rotation.
For example, I'm using single CRT,1024*768
when I rotate 90 degree, the on screen size changed to 768*1024, and will be
redrawed.

I want to know who redraw the on screen? how Xorg response when screen size
change?

Thanks in advance
