This happens to me periodically with Ubuntu 16.04.6 LTS, Kernel 4.14.114. External HDMI 1080p TV nVidia GTX 970M driven External HDMI 4K TV i915 Thunderbolt3 USB-C driven Internal Dell 1080p LCD i915 driven
Method: 1) close laptop lid with power & systemd set to "do nothing" 2) external monitors will disconnect (no signal) and have to move mouse to reconnect. 3) select GUI suspend from external monitor 4) power off external screens after system suspends 5) power on external screens 6) open laptop lid to resume 7) about 20% of time login screen appears and all work is lost If fixed in 17.10 would be nice to see backported to 16.04 as current plans for upgrade aren't until 20.04. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1753884 Title: session logout after suspend Status in gnome-shell package in Ubuntu: Fix Released Bug description: Only when I have a second monitor plugged in, if I close the lid of my laptop, my session gets logged out. What I'm expecting is the lock screen comes up. Sometimes (but not always) the second monitor will flash the "logged out" screen for a second or two before going dim. I have "Suspend even if external monitor is plugged in" enabled in Tweak Tools. WORKAROUND: Suspend via the GUI with the lid open. WORKAROUND: Unplug the second monitor before closing the lid.
