In Xorg newer than t9, Xorg stopped automatically loading the nouveau module, which causes no hdmi output on my GTX 670 card, except in virtual terminals. I tracked it down by by comparing Xorg logs.

Based on https://nouveau.freedesktop.org/InstallNouveau.html , I fixed it with

mkdir -p /etc/X11/xorg.conf.d
cat >/etc/X11/xorg.conf.d/20-nouveau.conf <<'EOF'
Section "Device"
Identifier "Device0"
Driver "nouveau"
EndSection
EOF

Then restarting Xorg.

I plan to look into fixing this regression and getting it backported to trisquel 10.

Its failing as early as xserver-xorg-core 1.20.1-3ubuntu2 (not sure exactly which of the many xorg package's fault it is).
