Hi, Raj.
Behavior on my testing systems with Xfce desktop environment is exactly
as you describe. I didn't think of it as a bug. There are lots of
lightweight lockers which behave similarly -- presenting a blank screen,
or perhaps a colored screen and awaiting password input without any kind
of feedback until the correct password is entered and the desktop
returns to normal.
I'm grateful for your post. I had never bothered to switch terminals to
see if it would have an effect. When I do so on these systems, I'm
presented with a screen with a message which says that the system is
locked and that I will be redirected to a login prompt in a few seconds.
I hope this is useful. Thank you for your post, as I prefer using a
prompt to typing my password at a blank screen.
Regards,
jp
