I'd imagine a workaround could be to have a hook for suspend write to the framebuffer, but I failed at getting this working when I tried today (put a script in /usr/lib/systemd/system-sleep to invoke eog in fullscreen).
Regarding the comment above about this being fixed in "certified" laptops, this doesn't seem to be 100% correct. See this on a Dell XPS 9350, and this machine was available in a "Developer edition" running Ubuntu. Still see this issue. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
