Mine has a Radeon.  Before upgrading it, if the screen blanked, the screen
would then go into a bizarre slow-motion state.  For example, you could see
a screen (such as when changing work spaces) repaint like a curtain drop on
a stage.  Took about 5 seconds to wipe from top of the screen to the bottom.
At least now, this appears to be much more stable as I've tried a number of
things that would affect this behavior in the past and it seems now to have
been annihilated.  Yeah!  

Now, if graphics were so simple, there would not be a gazillion pages to be
found with a Google search on graphics problems.  Graphics, sound, wireless
and wired ethernet, and bluetooth are still problem areas with Linux albeit
it is much better that in the early days.
