Just built a new PC. I am having a terrible time getting the proprietary ATI drivers installed. Here's my setup:

OS
Sidux (Debian Sid) release 2008.03, updated to latest kernel (2.6.27)

Power Supply
Coolermaster Real Power Pro 650W (ATX12V v2.3, SSI EPS 12V v2.91)

Motherboard
Asus P5Q SE, Socket 775, DDR2, PCIe 2.0, HD Audio, Gigabit LAN

Processor
Intel Core 2 Quad Q9550 2.83 GHz @ 1333 MHz FSB, 12MB L2 Cache

Internal Memory
Crucial 4x PC8500 2Gb (8Gb total)

Video Card
Diamond ATI Radeon HD 4870, 1024 Mb DDR5, 256 bit memory interface

Monitor
Samsung Syncmaster T220 22 inch Widescreen, 20000:1 contrast, 2ms refresh, 0.3W SoftPowerOff

I am getting an error which looks like this:

Code:
... skipped beginning (let me know if you need more) ...

Error: unable to open display (null)
I have tried installing several times using several different methods (uninstalling between each attempt). I have used kano's script for one install: http://kanotix.com/files/install-fglrx-debian.sh which was the latest and which resulted in the errors above. All of the attempts resulted in almost if not entirely identical errors. I have tried hacking up the xorg.conf file myself, and that did not improve the situation.

It looks to me like it thinks there are two cards, and wants to use crossfire. There is in fact only on Radeon HD 4870 installed.

How to I disable CrossFire (if that is indeed my issue)? Otherwise any ideas on getting this to work? Sidux default window manager is KDE btw, and right now it will not start. I am fairly experienced with both Debian and Ubuntu.

/var/log/syslog has this at the end:
Code:
kdm[6442]: X server for display :0 terminated unexpectedly
kdm[6442]: unable to fire up local display :0; disabling.
