Another workaround that I used for Cinnamon. I can't imagine it would be too much trouble to adapt it to other window managers: 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-battery-action as well if you're using a laptop). 2. Save the following script to a convenient location (it locks the screen, then suspends): #!/bin/bash cinnamon-screensaver-command -l systemctl suspend 3. Use the System Settings app (cinnamon-settings) to create a custom keybinding for the sleep key that points to the script. After this it behaves as it should.

After my computer wakes up I need to exit Viewnior (the image viewer I am using) so that the the file called, "My solid color image which obscures my desktop.png" disappears. I suppose the extra step would not be necessary if someone with some technical knowledge would explain how to cause i3lock to exit the image viewer after the computer wakes up. I use "viewnior --fullscreen" instead of "viewnior -f" because the later didn't seem to work in a terminal. I suppose this was a result of my using a French language terminal. Also, if you need to resize your image because you want it to appear centered on the screen, there's no need to install GIMP or any other draw or paint application. I used Google Drawings to resize "My solid color image which obscures my desktop.png" to match my screen size which is 1366 x 768 pixels. I went to File–>Page configuration–>Customize and typed 1366 then 768 and chose pixels. Then I downloaded "My solid color image which obscures my desktop.png" to my local drive.

[Bug 1280300] Re: Desktop contents displayed on resume, before lock screen is shown
There is no way to fix this as long as X11 is still being used. Lock screen timing issues are usually caused by a few different things: 1- Hardware issues. Certain models of computers have known issues where they don't generate the proper events when the laptop lid is closed or the suspend hotkey is pressed. In those cases, the laptop will enter the suspend state before notifying the OS, which results in the screen not being locked when the laptop wakes up. These issues need to be addressed with a firmware update, or with a quirk being added to whatever platform specific driver is in the kernel. This is the type of thing that is tested and fixed when a laptop gets certified and preloaded with Ubuntu. 2- Actual bugs in the screen locking code. This has happened in the past, and still occurs occasionally. 3- X11 not allowing the screen lock to forcibly remove keyboard and mouse grabs. This is the major reason why screen locking will never work reliably as long as we haven't switched to Wayland or Mir. For the screen to lock, it must be able to exclusively grab the keyboard or mouse. Unfortunately, there is no way under X11 to forcibly remove a keyboard or mouse grab that belongs to another application. When this happens, for example when you have a menu open, or you're using software such as Virtalbox, the screen is unable to lock before the laptop goes into suspend mode. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1280300 Title: Desktop contents displayed on resume, before lock screen is shown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/1280300/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1280300] Re: Desktop contents displayed on resume, before lock screen is shown
I have this issue with both Unity and Gnome 3. Running Ubuntu 15.10 on an Asus Zenbook UX305. I've also been able to type briefly before it autolocks (see 830348). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1280300 Title: Desktop contents displayed on resume, before lock screen is shown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/1280300/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Still seeing this bug (Ubuntu-Gnome 15.10, with Gnome 3) too. I too think this is a security issue. They don't even need to steal my laptop -- just flip it open and power it on briefly, and be ready with a smartphone to take a picture at the screen contents. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1280300 Title: Desktop contents displayed on resume, before lock screen is shown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/1280300/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1280300] Re: Desktop contents displayed on resume, before lock screen is shown
Still seeing this bug in Ubuntu 15.10 64-bit with Unity 3D, and have seen it in every Ubuntu version going back to at least 2011, across several different laptops from different manufacturers (Chromebook, Thinkpad, and Dell something-or-other). It happens reliably every time I resume from suspend - doesn't matter if I suspended through the menu or by closing the lid. How is this not considered a major security bug? If someone steals my laptop they can see anything I was doing before suspending. Information leakage like this should be treated as high priority. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1280300 Title: Desktop contents displayed on resume, before lock screen is shown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/1280300/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I did not experience it on my machine prior to 15.10, but after upgrading to 15.10 it happens consistently every time when resuming from suspend. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1280300 Title: Desktop contents displayed on resume, before lock screen is shown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/1280300/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
