Yes. Happens to me as well.

In your xorg.conf (gksu gedit /etc/X11/xorg.conf), you may have to
modify the virtual settings. For example:

	SubSection "Display"
		Depth	24
		Virtual	1280	1024

on this monitor and the login screen is fine. However, on my other
system, Virtual	1280 1024 causes the login screen to do exactly as you
describe. So on that system, I've modified to:

	SubSection "Display"
		Depth	24
		Virtual	1024	768

Try that (adjusting for your monitor of course). To test, just select
switch user, then you don't need to log out etc each time to test.
