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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1631715 Title: Password required twice returning from suspend Status in light-locker package in Ubuntu: Confirmed Status in xserver-xorg-video-nouveau package in Ubuntu: New 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.
