>>> The other thing to try to help speed things up is to disable DRI in

>>> problem too.
>>>
>>> To disables DRI, edit your /etc/X11/xorg.conf file.  In the "Device"

>>> Option "DRI" "off"
>>>
>>> Then reboot or restart X.

>> Many thanks! That is absolutely brilliant and now X.11 is fast and

>> 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.

> Ctrl-Alt-Backspace has been turned off for Jaunty.

> Try Alt-SysRq-K instead, or install the dontzap package.
