Many thanks! That is absolutely brilliant and now X.11 is fast and
fluid again on my machine. Wonderful tip - I am extremely grateful.

I did try, experimentally, switching back to Compiz with DRI off, but
it all went horribly wrong. Nothing appeared on a blank white screen
except corrupted icons for the alt-tab task switcher, and it seems the
Ctrl-Alt-Backspace shortcut to kill X no longer works.

10min of fiddling & a few reboots later, I'd reverted back to non-DRI
Metacity & all is normal again. I still have the keyboard issues to
resolve but I now think that is something else. I've also uninstalled
Compiz to make sure it doesn't accidentally get re-enabled.
