When I connect a second monitor to my HP Envy 14, it appears in xrandr
and can be enabled with:
xrandr --output HDMI-1 --mode 1440x900
However if I attempt anything but mirroring, for example placing the monitor
right of the main display X seems to crash.
xrandr --output HDMI-1 --mode 1440x900 --right-of LVDS
After pressing enter on this command I am kicked back into the lightdm login
screen. When I log back in the second monitor reverts to being disabled.
xrandr shows the following:
Screen 0: minimum 320 x 200, current 1600 x 900, maximum 8192 x 8192

I can't see anything written to Xorg.0.log file, the last output seems to be:

Disclaimer: I am running Awesome-WM and Cairo-composite-manager not the
default window manager. I am still using LightDM. Disabling Cairo does
not help. I have even tried launching gnome-settings-daemon to get the
gnome-control-center to work but this crashes in exactly the same way
after I click apply on the the dialogue box after enabling the second
monitor.
