After this crash, I rebooted and I'm currently running sway on wayland and
things seem to work well, but I've been having trouble with X for weeks now.

I first noticed issues when the following messages started appearing in my boot
logs:

nouveau 0000:01:00.0: bios: OOB 1 015f1901 015f1901
nouveau 0000:01:00.0: bios: OOB 1 b90900b8 b90900b8
nouveau 0000:01:00.0: bios: OOB 1 b90900b8 b90900b8
nouveau 0000:01:00.0: bios: OOB 1 b90900b8 b90900b8

I have a dual monitor setup and I was always running with no specific
xorg.config files, just the following in my .xinitrc file:

xrandr --output LVDS-1 --preferred
xrandr --output HDMI-1 --preferred --primary --left-of LVDS-1

But suddenly after some updates, that was resulting in the same content being
displayed on both screens, but I can still move my mouse cursor over onto the
second screen.

I put in the xorg.conf file that I used to use (already pasted in) and it
seemed to improve the situation, but there were still issues. The same content
would still appear on both screens, but once I let the xfce power management
shut off the monitors and then woke the computer back up, the screens would
work correctly again.

Then this I installed a new kernel and nouveau driver, and after starting X
everything froze and I found the Oops in my logs.
