'sudo systemctl suspend' works fine and I m prompted for my password on wake-up.
When I voluntarily ask the computer, it's ok too. I tried to reproduce the same conditions than when the bug occurred: I was watching a flash video in my web browser, and flash does not disable screen power off nor sleep mode when a video is playing. Unfortunately I did not reproduce the bug. If I encounter the bug again I will add more information here, hopefully I will find the conditions that led to the bug (I only saw it once but my Ubuntu 16.10 installation is fresh). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1633751 Title: No login prompt when waking up the computer from suspend Status in lightdm package in Ubuntu: Incomplete Bug description: Ubuntu 16.10 x64. * I let my computer go to sleep. * Several hours later I wake it up. Expected result: the lock screen is displayed, waiting for me to input my password. Actual result: I am directly back to my desktop.
