Subject: Buster s2ram resume screen sometimes shows last desktop
session, instead of lock screen.
Version: 3.30.2-3 amd64
On my amd64 (Kaby Lake) machine,
sometimes resume from suspend-to-ram shows
the last desktop session screen,
instead of lock screen.
Just hitting some key, lock screen appears, and since then
there is no problem.
Kaby Lake iGPU -> HDMI -> (recent) LCD.
This could be a potential security leakage issue, I guess.
However, I cannot find any suspicious/specific logs.
* posting to maintonly, not BTS itself.
* gdm3 package is just my guess.
