Hello,
I'm running Xfce4 on a recent install of Sid. I have configured Xfce4
to "Lock screen before sleep" (in Session and Startup / General), but
when I use xscreensaver, when resuming from suspend the screen is often
visible for a brief period before xscreensaver kicks in. I have not
seen this problem when using light-locker. ...
I can't make out whether I have misconfigured something here, or
whether this is a serious security bug in the current Xfce4 -
xscreensaver integration.
I can't shed any light on the cause, but can report I see the same thing on
a non-xfce system. I'm using lightdm and light-locker, then openbox,
although am using some xfce utilities.
Usually when booting up a flash of the previous user desktop is shown
before the login window. Agreed, this is not desirable at all. The only
possible culprit I can think of is xfdesktop4 - can you try booting to a
session with that disabled?
Forgot to mention - I'm not using xscreensaver.
I vaguely recall having a similar issue years ago. Managed to find it:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=520633
but now I read through I see it was nothing to do with xscreensaver.
