Xorg issues

ssl6 · 2010-12-08 13:54:53

i ran some updates a few days ago. and finally got around to rebooting last night (first mistake). anyway, after rebooting, i couldn't log into my desktop. i run kdemod. what was happening was, i would put in my credentials at the login screen, it would start the login process, and crash back to the login screen. couldn't really find anything in the X or kdm logs at this point that jumped out

so i started browsing around the arch and kdemod forums looking for recent posts of similar issues. and then i ended up trying to remove kdemod and try the standard kde from the arch repo's only to have the same problem.

then i thought, maybe something up with the nouveau drivers. so i removed nouveau, took the module out of modprobe.conf and ran mkinitcpio to make a new kernel image and installed the nvidia driver. tweaked my xorg.conf just slightly, and that worked with only one monitor anyway. so seemed to be an issue with nouveau

now, my problem is, i can't get my second monitor working with the nvidia drivers. X seems to segfault. essentially, the kdm login screen will load, flicker a few times, and X crashes.

here is my previous xorg.conf used with the nouveau drivers
http://sergeinc.dyndns.org/host/logs/xorg.nouveau

and my current xorg.conf for the nvidia driver with a single monitor
http://sergeinc.dyndns.org/host/logs/xorg.conf

and here's the nvidia configuration that segfaults
http://sergeinc.dyndns.org/host/logs/xorg.nvidia

some xorg logs
http://sergeinc.dyndns.org/host/logs/Xorg.0.log
http://sergeinc.dyndns.org/host/logs/Xorg.0.log.old

and kdm log
http://sergeinc.dyndns.org/host/logs/kdm.log

the rest of my system logs are in the same folder, if there's anything else that can help.
http://sergeinc.dyndns.org/host/logs/

maybe someone can help shed some light?

Not sure about kdemod and I only have limited experience with Twinview but since no one else helped yet I'll give it a shot.

Your Twinview configuration appears pretty messed up when looking at http://sergeinc.dyndns.org/host/logs/xorg.nvidia. I'd probably make a backup copy so you have it and then completely start from scratch with a minimal xorg.conf. Then as it says in the wiki (https://wiki.archlinux.org/index.php/NVIDIA) use:

Automatic configuration with multiple monitors
The NVIDIA package provides Twinview. This tool will help by automatically configuring all the monitors connected to your video card. This only works for multiple monitors on a single card. To configure Xorg Server with Twinview run:
nvidia-xconfig --twinview

to generate a proper twinview config to use as a base.

If it helps I use this for mine:

This is for mine which consists of one GPU and two monitors. One an LCD and the other a CRT. I'm using Twinview.

(Don't just use mine because it won't work)

And it's working although perhaps not fully optimal. Yours has what appears to be a lot of oddness to it such as it lists two separate GPUs (you really only have one?) and calls one of your same model number flat panels (?) a CRT. I think you'd be better off starting from scratch with your xorg.conf.

I have no xorg.conf on my machine, which has 2 flat panel monitors plugged into a Quadro FX 570.

To use twinview, all I had to do was edit /etc/X11/xorg.conf.d/20-nvidia.conf so that it looks like this

Section "Device"
        Identifier "Default nvidia Device"
        Driver "nvidia"
        Option "NoLogo" "True"
        Option "TwinView" "1"
        Option "metamodes" "DFP-0: nvidia-auto-select +0+0, DFP-1: nvidia-auto-select +1920+0"
EndSection
