Angry [multihead] second video card hangs computer at startx

OK, I am really at a loss here. I have been working on flushing my computer and getting it running almost nonstop for the past 24 hours. I even called in sick to work today I hope someone here can at least help me figure out what is going wrong.

So the top pretty much outlines the problem I am addressing in this post (although there are about two or three other ones but they belong in different categories). There is going to be a lot of stuff that I'm going to put here, I want to provide everything that I know about what has happened.

The box is a 500mhz PIII with 256mb ram
(just in case that might be needed, though i doubt it.)
a ATi Radeon 7000VE with two VGA heads and 16mb of ram
a Trident TVGA something (i'm not sure of the model number but I can get it if needed) with 4mb of ram

Ok, the system had been running a Slackware10 install directly from the CD's since 10.0 was released near the end of June (just three days before my birthday - best present ever!) I hadn't done much of anything to the system, and i was just running the dual-head card until July 4th when I added in the second card with the third monitor. Everything worked perfectly.

I don't remember everything that I did to the system but I do remeber that I...
- never recompiled the kernel. I used the stock 2.4.26 from the CD.
- installed the DRI binaries for my radeon.

Everything worked perfectly and I decided that it was time for a flush because I wanted to start over with a clean slate and begin using the 2.6.x kernel package in the testing/ directory. I formatted, re-installed, installed the new kernel, and got everything configured. Now when I run start my screens turned black and my computer hangs. CTRL-ALT-BACK and CTRL-ALT-F2 and the sorts don't bring it back, the only thing i can do is CTRL-ALT-DELETE and wait for it to reboot. I've also flushed it out again and just used the stock install with my configurations and it does the same thing.

I am completely positive that its the video card that is causing the hang. I've started and used my WM with startx -- -layout single and startx -- -layout dual and it booted up fine with the radeon card. I also changed the single-display layout to use the Trident and when i used startx it hangs just like the tri-display layout. I kept the xorg.conf that I used before, and then I re-made it to make it a lot cleaner and to see if something was left over that was messing it up. I have both files accessable on my webspace, links below.

That being said - Just incase its worth noting - I know its not the kernel or the newer version of X11 that I installed with Dropline-Gnome after the flush. Before I formatted, I installed both kernel and Dropline-Gnome 2.8 and it was still working perfectly. This problem didn't come up until after I formatted and reinstalled Slackware.

I have looked all over for a solution to this. The post in the URL above seemed to be pretty much the same problem but its a SiS card - I haven't been able to find any place that I can try out new Trident drivers. Of course, I could be totally misunderstanding that situation and it might be entirly different than this one.

this is my original xorg.conf file from before formatting my harddrive.
this is my current xorg.conf that I am using - a rewritten cleaned up version of the file above.
this is my Xorg.0.log from my /var/log directory.

Well, that is pretty much it for now. Thank you for actually reading through all of's a lot. If there is anything that I have forgotten but remember later, I will come back and add it. If there is any information or any files or commands that I should run, please let me know. I hope that someone can at least help me figure out what the problem is.

Sorry for not making the URL's hyperlinks. I can't post them with less than five posts. Just replace the X's with the appropriate characters.

Thanks again!

just a little bump.

I still haven't figured this out. It baffles me to no end.

OK, problem solved.

I just took the video card out, re-installed slack, and then put the card back in. Lo-and-behold it works now! I guess having it in the box at the time of installation might have messed up a configuration or something? Linux is crazy that way I suppose :\

Just in case anybody else has this problem, that might be a good thing to try out!
