Currently, after hitting the "Enter" key, for about 0.2 seconds a completely black screen is shown, with the default "X" cursor on it.
This does not look nice, nor does it seem to be strictly necessary: Neither kdm nor the gtk-greeter show such a glitch.
So, if possible, please provide a glitch-free login :)
This is great, thanks a lot :)
I just noticed one more problem: The cursor changes to the default "X" cursor for the fraction of a second. Is it possible to do anything about that?
(If however the work-around triggers the cursor bugs I experience with the gtk greeter, then I prefer this short flickering)
