Xorg log

This happens on newest Ubuntu (precise beta): login manager shows fine (on one screen, other has signal out of range, but that is normal), but trying to set the two screens side by side freezes X.

These work:
xrandr --newmode 2560x1600 268.00  2560 2608 2640 2720  1600 1603 1609 1646 +hsync -vsync
xrandr --addmode DisplayPort-0  2560x1600
xrandr --newmode "1280x800"x59.9   71.00  1280 1328 1360 1440  800 803 809 823 +hsync -vsync
xrandr --addmode DisplayPort-0  "1280x800"x59.9
xrandr --output DisplayPort-0 --mode 2560x1600

But this fails:
xrandr --output DisplayPort-0 --left-of DVI-0
