--- Comment #6 from Thomas Stewart <thomas at stewarts.org.uk> ---
Here is the status:
$ grep . /sys/class/drm/card*-*/status
/sys/class/drm/card0-DVI-D-1/status:disconnected
/sys/class/drm/card0-eDP-1/status:disconnected
/sys/class/drm/card1-DP-1/status:disconnected
/sys/class/drm/card1-DP-2/status:disconnected
/sys/class/drm/card1-DP-3/status:connected
/sys/class/drm/card1-DP-4/status:connected
/sys/class/drm/card1-DP-5/status:disconnected
/sys/class/drm/card1-eDP-2/status:connected
/sys/class/drm/card1-HDMI-A-1/status:disconnected
/sys/class/drm/card1-HDMI-A-2/status:disconnected
/sys/class/drm/card1-VGA-1/status:disconnected
$

I'm not sure about the DVI-D, I do have a thunderbolt socket on the laptop that
I have never used. I'm not sure if the card order has always been the same, but
it looks like card0 is nouveau and card1 is intel:

$ ls -l /sys/class/drm/card?/device/driver
lrwxrwxrwx 1 root root 0 May 27 17:36 /sys/class/drm/card0/device/driver ->
../../../../bus/pci/drivers/nouveau
lrwxrwxrwx 1 root root 0 May 27 17:35 /sys/class/drm/card1/device/driver ->
../../../bus/pci/drivers/i915
$

I rebooted without "nouveau.noaccel=1" and with "video=eDP-1:d" but it crashed
again in nv50_display_init(). I then rebooted with "nouveau.noaccel=1
video=eDP-1:d" and it seems stable but I'm not sure that has actually done
anything as dmesg and Xorg.0.log seem very similar.
