gdm: mirrors display.
kde: works (but KDE limits the resolution options to two or three for each screen)
xrandr: works
gnome classic: doesn't work
gnome shell: doesn't work
"doesn't work" means systemsettings->display notices both monitors, and will let you set resolutions, etc. except LVDS1 never switches on. systemsettings->display appears to think it is on.
xrandr --right-of results in a corrupt display. That's expected. This video card has a max width of 2048, so the main display (1920x1080) + any display to the right causes corruption.
I'm also attaching /var/log/Xorg.0.log and xrandr -q (after enabling the second display)

The following xrandr commands work as expected:
xrandr --output LVDS1 --mode 1366x768
xrandr --output LVDS1 --below VGA1
xrandr --output LVDS1 --pos 554x1080
