Re: Three monitors on FC5

That's gonna kinda make it hard to tell you what you're doing wrong...

Here is a more updated posting about this problem.
I just noticed that I forgot to post it on comp.os.linux.hardware.

====================================

I am struggling with a three monitor setup on a workstation running FC5.
The workstation should have three separate desktop (i.e the cursor should be
moving between all the monitors, but when an application is maximized it is
supposed to fill one screen - not all three).
I found a template xorg.conf file and by modifying it i managed to get a
signal to all monitors, but only flickering and no usable desktop.
I guess something is wrong in my /etc/X11/xorg.conf file, but I cannot see
what. I hope someone can identify the errors.

my xorg.conf file looks like this:
