--- Comment #16 from Elizabeth <elizabethx.de.la.torre.mena at intel.com> ---
Hi again, I failed to replicate on a BDW with HDMI. This is what I have done so
far:

1. Install debian sid
2. Update and upgrade system
3. Install newer kernel (because I needed to apply this patch
https://patchwork.kernel.org/patch/10156067/ for acpi)
3. Install fvwm
4. startx
5. Connect HDMI output (after booting had finished)
6. Used:
 xrandr --output eDP-1 --auto --output DP-2 --auto
--(above/below/left-of/right-of) eDP-1
7. No hang happened. (I can use terminal only on primary display, not sure if
it's expected from fvwm).

As for the AccelMethod, I did nothing to it:
gfx at debian:~$ sudo find / -name xorg.conf
/usr/share/doc/xserver-xorg-video-intel/xorg.conf
gfx at debian:~$ cat /usr/share/doc/xserver-xorg-video-intel/xorg.conf
Section "Device"
        Identifier "Intel"
        Driver "intel"
#       Option "AccelMethod" "uxa"
EndSection
gfx at debian:~$

What I'm missing to be able to replicate?

Thanks.

gfx at debian:~$ uname -a
Linux debian 4.16.0-rc6 #1 SMP Tue Mar 20 02:10:14 PDT 2018 x86_64 GNU/Linux
gfx at debian:~$ glxinfo | grep -i "opengl version"
OpenGL version string: 3.0 Mesa 17.3.6
gfx at debian:~$
