ATI Radeon graphic controler can save screenshots without power ???
I have ATI Radeon X1250-based graphics onboard (on my ASUS M2A-VM MotherBoard),
working fine... but every time i start my X Server (with gdm)
i can see a screenshot of the last session (just for a moment).
how can that be?
i checked this after:
1. having booted a windows,
2. shut down it
3. powered off my computer
4. started up my debian
then i saw the windows login screen before the (graphical) login manager has started.
when the last booted OS was my debian its just a screenshot of my debian login screen.
so my questions are:
1. why is my graphic card able to save that screenshot?
2. where does my x server (or my gdm???) take those screenshots from?
