Xorg won't start with nvidia driver, GLX fails to initialize

Hi all,

Just installed arch on a new machine, and I'm having trouble running X with the nvidia driver.  Following a clean install, installed X and nvidia

sudo pacman -S xorg-server xorg-server-utils xorg-apps xorg-xinit
sudo pacman -S nvidia

Rebooted and used "startx" to test X per the wiki. No joy.  Made a few changes suggested by the wiki

sudo nvidia-xconfig
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.d/20-nvidia.conf
sudo cp /usr/lib/modprobe.d/nvidia.conf /etc/modprobe.d/
sudo mkinitcpio -p linux

Rebooting again, startx again fails.  Installing gdm and gnome and starting gdm, a loop of X failure and restarts develops.

I've tried adding nvidia to /etc/mkinitcpio.conf

MODULES="nvidia"

And rebuilding the initramfs, which also didn't work.

I've extracted errors from the Xorg logs from starmtx:

Additionally, dmesg: http://paste.debian.net/163892

I'm out of ideas.  I feel like this is something obvious about loading GLX, but I can't find information about how to do that.

Re: Xorg won't start with nvidia driver, GLX fails to initialize

More searching, made some progress.  From this https://bbs.archlinux.org/viewtopic.php?id=166854 thread, replaced nvidia-mesa

sudo pacman -S nvidia-libgl

That fixed the GLX module problem.  Still remaining, failure to initialize DMA

[   244.059] (EE) NVIDIA(GPU-0): Failed to initialize DMA.
[   244.059] (EE)  *** Aborting ***
[   250.259] (EE)

Re: Xorg won't start with nvidia driver, GLX fails to initialize

Necrobump for anyone googling this:

The error seems to be the result of a hardware fault.  Replacing with another GTX 970 leads to successful startup after installing packages per the wiki.
