Xorg troubles on Slamd64
 
I can't seem to get xorg to run at 1200x800 on my Compaq Presario R3000 series laptop under the unofficial AMD64 port of Slackware. What is strange though, is I just happen to have saved my xorg.conf file from when I had it up and running previously under Fedora (yep...not a problem...took some tweaking but got it working). I get X to start and the Nvidia drivers to load, but the display is all hosed up. It's almost as though the box does not think my horizontal and vertical refresh rates are right. The display is like half the screen and stretches beyond the screen when going up and down. When I go with the vesa settings and just load it up that way, I have no problem although it is ugly as heck.

How is it that the horizontal and vertical refresh rates would work fine under one distro, because they are the exact same ones I used under Fedora Core, and not another? I would think hardware is hardware and xorg is xorg. Anybody got Slackware working with xorg @ 1200x800?

What is even stranger, is I decided to just remove the xorg file under /etc/X11. When I removed xorg.conf, and typed startx, X still starts. It's almost like it is reading the conf file from elsewhere. Looking over at the Slackware site itself, I read a bit, decided to try xorgsetup and I still have the same problem. I was trying this under kernel 2.6.10 with the last three NVIDIA drivers for X86_64. I thought perhaps I might have better luck with 2.6.11.5, but I didn't. If any of you have any suggestions, I would really appreciate your sharing them with me. I'm lost. Have no idea how x starts without a xorg.conf file under /etc/X11. But it does.

Fixed it. :)

Strangely enough, at least when logged in as root, it appears that Xorg will accept a xorg.conf file from places other than /etc/X11. I found this out when I ran xorgsetup again, as it had made mention of the fact that it already found a xorg.conf file, which I had in under /root. It said that it would rename the file xorg.conf.bak, and it did under this directory, which explains my ghost config file problem.

However, it turns out I have not fixed it after all. The problem with the screwed up display is the nvidia driver. If I remove the nvidia portion out of the xorg.conf file and replace it with nv my display is low quality, but at the appropriate resoultion :(

Ok...fixed it for real this time. Interesting little fight with the nvidia drivers. 2.6.11.5 and the latest Nvidia drivers for X86_64. Here was the kicker:

I put the following in /etc/modprobe.conf

options nvidia NVreg_Mobile=0

Once I did that, she worked like a champ. Here is my xorg.conf file for anybody out there who needs a hand:
