ATI 6.7.192 Dual-Head

[Red Neck]

Hi,



My setup is an ATI Radeon X300SE card which is powering two identical DVI LCD monitors through DualHead enabled via MergedFB.  Recently I updated my machine to Xorg 7.3 and ATI driver 6.7.192 which has subsequently broken my DualHead setup in that my second LCD no longer receives any signal.

Now I believe I have got my config correct (attached) in switching off the no longer supported MergedFB and using XRandr to control output.  When running xrandr (on one LCD) I get the following output (verbose config attached):



Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 2560 x 1024

DVI-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm

   1280x1024      60.0*+   75.0     59.9  

   1152x864       74.8  

   1024x768       75.1     60.0  

   800x600        75.0     60.3  

   640x480        75.0     60.0  

   720x400        70.1  

DVI-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 376mm x 301mm

   1280x1024      60.0*+   75.0     59.9  

   1152x864       74.8  

   1024x768       75.1     60.0  

   800x600        75.0     60.3  

   640x480        75.0     60.0  

   720x400        70.1  





If I run what I think should output to the second LCD:
  xrandr --output DVI-0 --mode 1280x1024 --same-as DVI-1
I still get no output.

I have checked out and compiled the latest driver from the Xorg git repositry as of speaking (commit dc333884c540d536bffe51a5ebfaf1822af6a91c, Tue Sep 18 22:23:12 2007 -0400) but this hasn't improved anything.

Can anyone offer any assistance?

Thanks,

K.Cender
