I *think* that means: Feb 03 21:06:04 User enters password to unlock. Feb 03 21:06:36 System rejoins wifi network. Feb 03 21:08:32 Xorg wakes up and redetects the connected monitor. So the first thing I would try is to disable wifi before sleeping. Does that then make waking up faster? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1774188 Title: Unlocking the screen takes 5 seconds in Xorg sessions (not so much in Wayland sessions) Status in gdm3 package in Ubuntu: Confirmed Status in gnome-shell package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Status in xorg-server package in Ubuntu: Confirmed Bug description: This is a fresh installation of 18.04.
