ATI dual screen not working in 9.04
I'm running an ATI Radeon X1950 Pro, it was working fine in 8.10, but since upgrading to 9.04 I can't get dual screen graphics to work at all.
Immediately after the upgrade to 9.04, I couldn't log on. Any attempt to do so just crashed me straight back to the logon screen, similar to the problem reported here:

I managed to log in after removing my entire .config directory, but then found that I could not configure dual screen graphics. Although the graphics card and both monitors appear to be detected fine, any attempt to turn off 'clone' mode immediately crashed Ubuntu back to the logon screen, and prevented that account logging in until I removed the .config directory again.
Next I tried the ATI drivers, going to System -> Administration -> Hardware Drivers to enable them. They installed fine, but after rebooting I had a completely corrupted display, the screen was unreadable and unusable. Even in recovery text mode I was getting graphics corruption and strange characters appearing on the display, but I managed to recover by removing the ATI drivers with the command:
# apt-get remove --purge xorg-driver-fglrx
However, I'm now stuck for ideas. Neither the default nor ATI drivers appear to work now, whereas in 8.10 I was able to run two screens absolutely fine.
