Lenovo T460s Mate 18.04
Observed Behavior: computer has lid closed and in sleep. opening the screen results in password protected lockscreen. However, plugging in external monitor on HDMI bypasses the lockscreen and goes straight to the user’s desktop. Laptop is set to turn off built in screen upon connection to external screen on HDMI rather than “mirror” or “extend”. The “lock screen now” widget in the panel stops working after I bypass the login screen in this manner.
Expected Behavior: it should not be possible to bypass lock-screen without entering password no matter what display is used
