Hi- I'm using the latest xrandr and radeonhd gits and I can't seem to get
multiple monitors to work how I'd like. I can enable my external monitor
only as a clone of the primary one- when I try to set it as a display to
the left or right, X crashes. I have a Thinkpad T60 with a Mobility X1400
and run ubuntu gutsy (so it might be a problem with the xserver- it's not
the current version.) Is this something that should be working and I'm
not finagling it right, or do you guys want some logs?

Have success with similar T60 under FreeBSD.

Only special hint - do not use option PreferredMode in xorg.conf, it
puts Xserver into infinite loop. Instead, just put xrandr call to
startup scripts.
