External GPU Issues

So, I'm trying to figure out how to get my eGPU working again. Since I don't really know what happened to cause Arch to start defaulting to my laptop's internal card and display--despite the Xorg file telling it to go to the external card and monitor--I'm just going to give a rundown of what was going on when this started happening.

1. I decided to play Battlefield: Bad Company 2 through Wine.
2. Game runs okay, no issues until 3.
3. I decide to get into a tank. After trying to kill another tank, the game locks up completely.
4. Alt+F4 did not close the game, and the rest of my system was locked up.
5. Use Ctrl+Alt+Backspace to kill X.
6. X restarted, but started to use my laptop's display.

Since I had the configuration for the external graphics card saved in another file off in another folder, I removed the old Xorg.conf, restarted the computer, and then re-copied the configuration back into place like I've done any other time I've needed to unplug from/plug back in the external graphics card. For reference, I currently have my eGPU set up to run through my laptop's ExpressCard slot; the card itself is an AMD R7 240.  :unsure:

Xorg Config:

Section "Device"
	Identifier "eGPU"
	Driver "ATI"
	BusID "PCI:5:0:0"
EndSection

Section "Monitor"
	Identifier "external"
	HorizSync 24-83
	VertRefresh 50-77
EndSection

Section "Screen"
	Identifier "Screen 1"
	Device "eGPU"
	Monitor "external"
	DefaultDepth 24
	SubSection "Display"
		Depth 24
		Modes "1280x1024"
	EndSubSection
EndSection

Re: External GPU Issues

check the Xorg log?
see /var/log/Xorg.0.log or ~/.local/share/xorg/Xorg.0.log
