Ubuntu – I cannot set up dual monitors to work with 11.10 using amdcccle 11.9

dualheadfglrxgnomemultiple-monitorsxorg

I've installed the ati catalyst drivers 11.9 manually because the default ones don't work with gnome-shell. But when that I try to change the settings in amdcccle(adminstrative) to use multi-display, the application closes and doesn't change anything or asks me to confirm and still doesn't save at all.

This is my xorg.conf http://pastebin.com/P5XmNKfM
How can I fix this?

The steps that (eventually) worked for me on 11.10 (Oneiric) with a 1680x1050 22" and 1024x1280 19" (counter-clockwise ;)):

[Skip to important/troublesome steps in bold]

  1. Install the "ATI/AMD proprietary FGLRX graphics driver" (the "post-release updates" version failed for me)
  2. Reboot and see the horrible mirrorring at low res
  3. Use amdcccle(adminstrative) (after experiencing the horrible crashing of this question), and
    1. Disable the second monitor
    2. Apply
    3. Re-enable the monitors with all the settings that you want
    4. Apply/OK etc

  4. Log-off and on and see if it sticks: if it doesn't (it didn't for me)

    1. Redo 3
    2. Go to the normal display settings control panel and save (I don't think this is necessary, but it's what I did)

    3. Open Terminal and

      cd /etc/X11
sudo mv xorg.conf.ati xorg.conf.ati.bak
sudo cp xorg.conf xorg.conf.ati

      Your settings should stick now.

I would think that simply doing step 3 then sudo rm /etc/X11/xorg.conf.ati would work, but I'm not about to mess it up :).
