This problem will occur if running vivid with the overlay PPA [1]. We can't SRU this change to vivid since this will break users not using the PPA. There is an option to put a modified version of LightDM in the PPA, but I'm not going to do that as that will create a maintenance issue.
If this is an issue I think the best workaround is probably to set the command for unity-system-compositor in lightdm.conf: [SeatDefaults] unity-system-compositor-command=/usr/sbin/unity-system-compositor.wrapper And then strip out the --enable-hardware cursor in this wrapper script.
