Yep, that's exactly what I see, and your workaround works perfectly for 
me as well, suggesting it's the same problem. Interesting that you've 
had it since 9.04 and only occasionally, whereas I never had this happen 
with 9.04 but have had it 100% consistently since upgrading to 9.10.

Perhaps this is irrelevant, but just for completeness I should mention 
that I upgraded to 9.10 with a developer version, before the official 
release, but only a month or so.

Clearly this problem has nothing to do with the gnome-screensaver 
password dialogue box. It probably has to do with the video driver not 
resetting or clearing memory, and by switching to a virtual console and 
back we force it to reset something.

Not a big issue, but I'm extremely curious. I'd love to know what's 
going on.
