Bug Description
I had 11.10 64bit, I upgraded to 12.04
if I change the settings in the Display it will freeze .
- if I move the external monitor to the left of laptop monitor , (or above it) it will freeze
- if I try to turn of the laptop monitor ,so I only have my external monitor it will freeze again.
the mouse wont move and I have to reset the computer by ALT PRINT K to come back to ubuntu
dual monitor used to work fine in ubuntu 11.10 , is there any way to downgrade the Display program to the one in 11.10 ?

Xorg log
I have Archlinux (linux-3.2.9) running on Radeon 4550 using radeon with xf86-video-ati 6.14.3, xorg 1.12 and mesa 8.0.1.
I have two monitors attached using DVI (Dell 2408WFP) and HDMI (Toshiba TV).
While running
xrandr --output HDMI-0 --auto
xrandr --output HDMI-0 --below DVI-0
Xorg hangs.
Here is the Xorg.0.log (full log is attached):

The same behaviour is seen using xf86-video-ati-git and xorg-git.
