'gnome-screensaver' isn't used in any modern versions of Ubuntu so this
needs to be reassigned and/or merged with bug 1532508...
** Package changed: gnome-screensaver (Ubuntu) => ubuntu

We're mid 2021 and this security issue is still present.
Confirmed on Ubuntu 20.04. Also on Zorin OS 15 (Ubuntu 18.04 based).
Besides only getting medium priority, I cannot understand that this
medium priority security issue hasn't been assigned, leave alone fixed
in nearly 7 years.

The issue still persists in Ubuntu 20.04. Running mate with lightdm and

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).

I also experience this buggy behavior on a fresh install of Ubuntu
18.04, using the default Gnome Shell desktop. This bug has been around
for at least 7 years (see https://bugs.launchpad.net/ubuntu/+source

as #49579 -- if you have a menu open or a virtualbox window to a guest

That's why we recommend using the lock interface in the menus or

Another workaround that I used for Cinnamon. I can't imagine it would be

Mark, thanks for such detailed explanation and extremely fast response!
It's grave news for me to hear that X11 is the major problem here. Would
it be better if your publish it in Ubuntu FAQ (or elsewhere) and close
all these bugs with "won't fix" to make community realize the point?

There is no way to fix this as long as X11 is still being used. Lock
