Desktop visible after resume (from suspend) and before screen is locke

skrat · 2013-07-04 12:21:42

My desktop becomes visible for brief period (<1s) when the system resumes from suspended state. My desktop env. is XFCE4, it happens with both xscreensaver and gnome-screensaver (also with slimlock and i3lock), therefore I think it's not locker dependent. It's a major security flaw because sensitive information may be exposed (not just porn). Using both XFCE provided locking facilities (suspend/resume lock options in Power Manager and Session settings), and systemd suspend/resume hooks yields same result. I remember back then when I was using Gnome, I haven't had this issues. Does anyone have any idea how to prevent this desktop expose?

It also happens in KDE.

Have you tried this --> https://wiki.archlinux.org/index.php/Pm … or_suspend ?

This seems to be present in a lot of distros. This is a workaround I'm using for Cinnamon on Debian, but it should be possible to do something similar with other distro/window manager combinations:

1. Use dconf-editor to change the button-suspend action at org>cinnamon>settings-daemon>plugins>power to 'nothing' (you could also amend lid-close-ac-action and lid-close-bettery-action as well if you're using a laptop).

2. Save the following script to a convenient location:

#!/bin/bash
cinnamon-screensaver-command -l		#lock the screen (use 'gnome-screensaver-command -l' if you're using the gnome screensaver package)
systemctl suspend			#suspend the system

3. Use the System Settings app to create a custom keybinding for the sleep key that points to the script.

After this it behaves as it should. You can see the lock screen pop up briefly before it goes to sleep, which is reassuring.
