So, there're 2 graphics cards and Xorg's picked the nvidia one, which is crashing

```

with a bizarre `amdgpu' error message?? The Linux kernel's picked the Intel
card for display:

```
Graphics:
  Device-1: Intel 2nd Generation Core Processor Family Integrated Graphics
    driver: i915 v: kernel
  Device-2: NVIDIA GF108M [GeForce GT 550M] driver: N/A
  Device-3: Syntek USB Video Device driver: uvcvideo type: USB
  Display: server: X.Org v: 1.21.1.7 driver: X: loaded: modesetting

  API: OpenGL v: 4.5 vendor: x.org mesa v: 22.3.6 renderer: llvmpipe (LLVM
    15.0.6 256 bits)
```

OK, try these:

1. In BIOS, disable the nvidia card

2. If you can't disable, try this Xorg config fragment:

/etc/X11/xorg.conf.d/asus-nb.conf:

```
Section "Device"
	Identifier "Card0"

	Driver "modesetting"		# preferred
	# Driver "intel"
	# Driver "nouveau"

	# nail-down card
	BusID  "pci:0:2:0"		# Intel card
	# BusID  "pci:1:0:0"		# nvidia card
EndSection
```

If the "modesetting" driver has issues, choose the card-specific driver.
