I found a bug in ubuntu At the login screen
buster/sid
Linux 4.15.0-24-generic #26-Ubuntu SMP Wed Jun 13 08:44:47 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
I use my work laptop and today when I came back to office I connected both my external monitor.
1 HDMI cable and 1 Mini display port cable.
Then I realize one screen on the right had my login screen prompting for password and the left monitor was unlock, I was able to navigate the mouse and use the computer just fine. However all the keyboard input was sent to the password prompt.
I did the test a couple time and each time I was able to reproduce the issue.
#1: Lock the computer
#2: Disconnect both external monitor
#3: Reconnect external monitor ( my sequence was HDMI -> Display port )
#4: You've bypass the login screen.
When doing the demo to my colleague I was able to completely bypass the login screen on both screen and had complete mouse and keyboard input. At that time I was not able anymore to lock my session. I had to reboot the laptop.
