[SOLVED] Xorg segmentation fault with Nvidia driver

A few months ago I was having problems with hard video lockups with the Nvidia driver: https://forum.artixlinux.org/index.php/topic,2210
They disappeared for a while but they same symptoms are present again. Last time around the Xorg logs did not show anything useful but now they show segfaults and some other stuff. I have determined that the system is still fine, as I can ssh into it, but the video is completely dead, and I can't even switch tty. I am now using the nouveau driver temporarily (hopefully) and it doesn't seem to be giving me any problems, but I need to be able to use the proprietary driver. I have tried using different versions of the nvidia drivers, incluuding dkms and regular, and different kernel versions but nothing helps. I have attached the most verbose of the Xorg logs that I have been able to save.

Well I'm sure you probably expected this, but this is can only be a driver bug of some sort. Since it apparently segfaults, NVIDIA has to fix their code somewhere.

Yeah, that's what I thought. I'm not using nvidia by choice but I'll have to stick to nouveau for now. Thanks for the help.
