Bug Description

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.
