[OLPC-AU] Sugar on Mirrored on Dual Monitors

[Peter Hewitt]

Not sure where to pose this question but I'll start here. Have made some 
progress from web searching but am now stuck - I'm very new to linux and sugar.

I'm running SoaS v3 on a Dell Latitude D400 and want to mirror the display 
on another monitor.

When monitor 2 is an old CRT it mirrors but when I use a flatscreen I get 
an extended display instead. My reading says that this is the default 
behavior with Fedora 13. Of course I want it to work on the flatscreen!

I found that

xrandr --output VGA1 --same-as LVDS1

in a terminal session does the trick but it's back to extended when I leave 
the terminal session.

Hope someone can help.
