It seems to me that gdm is pretty 'unintelligent' regarding screen
resolutions etc.  When I set my resolution to 1600x1200 in X all sorts
of oddities appeared when going into and out of X from gdm.  The login
screen is some other resolution than 1600x1200 (not quite sure what)
then after logging in a screen with a cursor appears at low
resolution, this then disappears (blank screen) for a few seconds and
finally my X desktop starts appearing at 1600x1200.

It all seems a bit messy and amateurish.
