Password required twice returning from suspend

light-locker (Ubuntu)

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

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.

If you are still affected by this bug, please obtain a debug log:

killall light-locker; light-locker --debug

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?
