LinuxQuestions.org - Fedora C2/Radeon 9600SE Dual Head/Second Monitor not working properly

Hello.

Right, here's the deal:

I've only just recently set up Fedora Core 2 on a system with an ATI Radeon 9600SE which has one VGA and one DVI-out.
I've got two BENQ FP767 LCD displays attached to this device (the second monitor on the DVI out is connected to a DVI-VGA adapter) and I'd like to have some nice dual monitor support here.

I've installed the newest ATI drivers from their website, following the instructions on fedorafaq.org/#radeon to the very letter and everything seemed to work just fine.
Well, until I started X that is.

As soon as I had installed the driver, run "fglrxconfig" and "telinit 5"-ed the second monitor showed an utterly distorted clone of the first monitor's contents. The strange thing, however, is that I can move the mousepointer over to the second monitor without any problems whatsoever (it's not even being distorted, it's displayed just as if there were nothing to it).

Running "fglrxinfo" yields the following result (I removed the "www"-part in the mesa3d.org URL because the board would not let me post this thread otherwise):

Code:

[root@pc-ms X11]# fglrxinfo

display: :0.0  screen: 0

OpenGL vendor string: ATI Technologies Inc.

OpenGL renderer string: RADEON 9600SE Generic

OpenGL version string: 1.3 (X4.3.0-3.11.1)

 

 

 

display: :0.0  screen: 1

OpenGL vendor string: Mesa project: mesa3d.org

OpenGL renderer string: Mesa GLX Indirect

OpenGL version string: 1.2 (1.4 Mesa 5.0.2)

This is strange because:

fglrxconfig did not yield any errors whatsoever, it let me configure both monitors, refresh and sync rates (which, by the way, I am sure I have configured properly, I looked up these values at BENQ's website)
I have checked the /etc/X11/xorg.conf over and over, I have tried configuring both monitors, screens and graphic-card connectors identically (except of different identifiers of course), without any result
That MESA driver istn't loaded anywhere in the xorg.conf, only ATI stuff in there.

Attempting to configure the card via Start Panel - System Settings - Display also failed, I cannot select a second graphics card for dual-head configuration there (which is quite reasonable after all, seeing as I only have one graphics adapter ;)

So, here's my xorg.conf file (I only removed the "Input Devices" sections in order to keep post length down), I hope someone can help me out of this "misery". I'd really like to get rid of Windows entirely but if I can't even get my second monitor to work properly I'm afraid I'll be stuck with Bill's malware for quite some more time ;)
