I know it well, because I get notifications frequently that my system is too 
slow and that the desktops effects are being suspended. This notification 
also mentions how to toggle the effects back via this key combination.

I have a dual core AMD 4850e CPU with 2.5 GHz, and on-board Radeon HD3200 
video (using the open-source radeon driver). Which seems to be barely enough 
to run KDE4 (using six desktops and running much stuff I must admit). top 
gives these values, sampled over two minutes:

  27% X
  16% kwin
  13% plasma-desktop
   5% amarok
   5% dbus-daemon
   3% udisks-daemon
   3% akonadi_imap_re
   3% akonadiserver
   3% mysqld
   2% kget
   2% knotify4

Right, I just mentioned it as yet another way to turn it off. Now let's both 
forget about it, as Stephen provided a much better solution.
