Hi Noop,
i configured the repo as mentioned in the link you gave,
and tried to install gnome screensaver. but it didn't get installed and
said its already installed.
so i uninstalled it and reinstalled it.
but still i have the problem and now even i get this problem when i
lockscreen and switch user.


btw. the lockscreen thing worked earlier only if i don't do anything in
the second user and just log out back.

thanks.
