I have added some additional information related to this bug at the launchpad version: https://bugs.launchpad.net/lightdm/+bug/1024482
As far as I can tell, the problem is that if anyone sets the cursor on the root window, all of the applications will inherit the root window's cursor for the default left pointer unless the application explicitly sets one (as I believe Firefox does, which is why hovering over that window after changing the cursor theme/size will show the new theme correctly). lightdm-gtk-greeter (and unity-greeter as well) both set the cursor on the root window, which is why I think lightdm is triggering the bug. If lightdm-gtk-greeter is patched to set the cursor on individual widget windows instead of the root window, cursor theme changes work as expected. (Not suggesting this as a fix, this may be an xorg or gtk bug) Jason Conti -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
