I'm trying to set up two monitors on a CentOS 5.8 box.
I'm using a Nvidia GeForce 9800 GT graphics card
I have two Acer G2267HQL monitors. (Just a couple basic Wide LCDs)
I've downloaded and installed the latest NVIDIA driver. 304.60
My 5.8 version is completely up to date.
When I YUM, I also go to ELEP and RpmForge.
I've spent all day on this problem. So far.
This morning I tried and tried to get the /etc/X11/xorg.conf file just right.
(not too soft, not too hard. Not too hot, not too cold.)
I even had example xorg.conf files from friends, from working Linux Redhat 5.8 dual monitor machines. Didn't seem to help.
At one point I discovered the nvidia-settings GUI tool. (I appreciate the hundreds of man-hours that went into the README file, but one screen capture of the real GUI, would have saved me many many hours)
Here's the thing.
Using the /usr/bin/nvidia-settings GUI, I CAN get both monitors working as one spanned display. I even have saved a new xorg.conf file while they are working correctly. I've even done that after deleting the current xorg.conf file. (So there is no xorg.conf file in /etc/X11)
Yet. If I go to Init 3 and back to Init 5, or logout and back in, or reboot, or restart the Xserver. I lose that 2nd monitor. At which point I can go into nvidia-settings and fix it again. It just won't stay that way.
A clue to what is going on is that, I believe that I have a good xorg.conf file. Because when I log in as ROOT, I get two monitors working with a spanned display. It comes up that way.
So it works if I log in as ROOT, but not if I log in as this lowly user.
Can anyone point me to the file permission, or lock file, or whatever could be my problem?
