xorg.conf edit 4

So I'm back at square one, having tried a whole bunch of things, no luck.

"cat /var/log/gdm/:0.log" gives me:

(==) Log file: "/var/log/Xorg.93.log", Time: Mon May  7 16:45:59 2007
(==) Using config file: "/etc/X11/xorg.conf"

man page for xorg.conf

This geezer reckons AIGLX is incompatible with newer Xorg server, so I want a bit of:

  Section "ServerFlags"
      Option  "AIGLX" "off"
  EndSection
  Section "Extensions"
      Option "Composite" "Disable"
  EndSection

...coming right up!
