Bug Description

Clean install - no updates available.

Suspend machine and restart.

Lock screen requiring password - enter password and return to suspended desktop.

Within a few seconds machine locks and password is required once more.

Appears to depend on how fast I enter the password the first time.

Using the same hardware I've installed nvidia 340.96 and tried to reproduce the issue without success.

Noted that if I wait a few seconds at login password dialogue I don't get the double password requirement.

If it can't, I have the same bug on Arch Linux (precisely Antergos XFCE).

It happens with both the gtk and webkit2 greeters.

Maybe it's related to bug 1284918 https://bugs.launchpad.net/ubuntu/+source/xubuntu-default-settings/+bug/1284918

I solved it on Arch Linux by going in Light Locker Settings → Automatically lock the session → Never.
It's still locked because Xfce Power Manager has a redundant setting (in Security), maybe this is the cause in my case.

Thanks. I am not quite sure yet how to interpret the log.

I suggest attaching a log for the second test case also (comment #4).

Does it work better, if you turn off automatic locking on suspend via power manager settings and run 'xflock4 && xfce4-session-logout --suspend' in terminal, instead?

I'm seeing this issue for the first time in Ubuntu 19.10 (eoan).

Both the screensaver and the power manager have preferences for locking. I see this issue when both are enabled.

Under: Screensaver Preferences -> Lock Screen, I see:
Enable Lock Screen: Y/N
Lock Screen with Screensaver: Y/N
  Lock the screen after the screensaver is active for ___ minutes
Lock Screen with System Sleep: Y/N

Under: Xfce Power Manager -> Security, I see:
Light Locker:
  Automatically lock the session: Never/When screensaver is activated/When screensaver is deactivated
  Delay locking after screensaver for [1 to 61] minutes
  [Check] Lock screen when system is going to sleep

If I disable everything in one of those two places, I don't get the double locking.

Stephen, do you use xfce4-screensaver? Is the other lock screen from light-locker. You do not have to use both. Check your autostarts. Purging light-locker changes power manager settings UI, but there is still checkbox for locking.
