This sounds like a duplicate of existing similar bug reports. To confirm this, please try waking the machine from sleep but not entering your password. Does the display become obscured a short time after waking still?

The short answer is no, there does not seem to be a time after which it will mask itself. It will blank again, but if you wake it again, the secondary display will still be unmasked while the primary is masked and waiting for me to start the password sequence.

The long answer is that further testing reveals at least a part of my statement to be incorrect, though I feel that is a change (I let the system update almost every day).

First, the expectation that I have here that is being violated is simply that I expect that my screens will be masked and require a password if the system is waked by any means after it suspends for any reason. As an aside, I can't find the customary require password on wake setting anywhere though the system is requiring a password. The violation I've seen is that the primary screen is masked and the secondary is not under some circumstances.

I stated "When I wake the system after suspending it" and the truth is that this is only happening now when it has suspended itself. If I suspend it using the keyboard sequence to manually activate the suspension, all is clean. If it suspends itself due to inactivity, after waking it to enter the password, I can see the laptop display with nothing obscured. After a while, it will go dark again, but if I wake it again it will still not be obscured.

At the start of this session, I did witness the laptop display showing open windows while the primary display was obscured and required me to enter my password. So I know the problem is still present.

Other problems and/or unusual factors are likely mixed in.

In my setup power panel, "automatic suspend" is off as are the "on battery power" and "plugged in" options in the subpanel. "Dim screen when inactive" is off. "Blank screen" is never. "Screen Lock" under the privacy settings is also off. Yet, the displays do turn off after about 30 minutes of inactivity, and, even later, the system does automatically suspend.

Possibly related - I have changed my "Primary Display" option so that the external display is primary by clicking on "primary display" in the display arrangement panel and selecting the external display. So the password box comes up on the external display, not the primary one. My display mode is "Join Displays". The external (primary) display with the username and/or password box is masked as it should be at all times.

I always operate on power, so battery settings should be irrelevant in this.
