ATI card + OS driver + multi monitor

Question

Hello everyone,
I'm stuck configuring the RadeonHD drivers for multi monitor setup. The system starts with both screens cloned; logging in is in clone mode too. After that the second display is being turned of (no signal). Using xrandr --auto will enable the second display to life and clones the sreen again. xrandr --output DVI-I_1/analog --left-of DVI-I_2/analog will create a big desktop only the second display can only be used for a half screen mouse will go further anything else will not.
I've started with a autogenerated, by xorg, xorg.conf file and tweaked to the one below
xorg.conf
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0

My Xorg.0.log shows the line (WW) RADEONHD(0): Option "monitor-DVI_I_2/analog" is not used wich puzzles me!
Information:
X.Org X Server 1.7.1.901 (1.7.2 RC 1)
xrandr program version       1.3.2
Server reports RandR version 1.3
xf86-video-radeonhd 1.3.0-1
If more information, from Xorg.0.log or anywhere else, is needed just ask....
Thanks in advance,
Arjan Gelderblom

Sorry for the delay, but I was away for the weekend!

xrandr --output DVI-I_2/analog --right-of DVI-I_1/analog
This doens't change much except that now the smaller monitor has the problems!

Changed to ati instead of the radeonhd drivers still gives the same error!

I think you need to set a valid virtual size in your xorg. I think the one you have commented out is too large.
Mine is:

Because of the switch to ati from radeon the log is different now... but here it is: http://pastebin.com/m77d0ea0b
This one at least shows that my seccond monitor is connected which failed in radeonhd!
Thanks for all the help,
