Wow... One of us is really confused, and I'm beginning to think it's not me.

First, I asked to see the /var/log/Xorg.0.log file that is generated when you aren't using an xorg.conf file. You are clearly using an xorg.conf file:


That's the nvidia card, not the radeon 8500DV. I'm trying to find out what goes wrong with the radeon driver, so showing the log file that is generated when using the nvidia card is pointless.

But, hey, if you have something working that you are happy with, fine. I suggest you mark this thread solved.

Possibly...
No sir. That's what it generates. Before I ran "startx" to generate the log file I posted, I logged on as root, went to /etc/X11/ and performed "mv ./xorg.conf xorg.conf.old", even performing ls to be sure that there is nor xorg.conf in that directory. I just tried it again to be certain.

My bad. I wasn't going to swap out cards. It should work with the nVidia card without having an xorg.conf file too, but it doesn't, which is what I was trying to demonstrate.

Done and done.

Well that could be part of the problem, then. Take a look at what your log file showed, what I quoted from it. It's reading /etc/xorg.conf not /etc/X11/xorg.conf. So if you were removing /etc/X11/xorg.conf and thinking you were trying without an xorg.conf file, the presence of /etc/xorg.conf was screwing you up :-)

that is all.

Have you tried running xorgsetup? Using Slackware, it works well for me. I'm wondering if it would've worked right away for you, and save a lot of trouble.
EDIT!
I meant xorgsetup, not xorgconfig.
