OK then it sounds like a kernel configuration problem where the system is sleeping some components too deeply to wake up.
Do you have 'tlp' installed? If so then it's a tlp bug/feature. Just uninstall tlp. If you don't have 'tlp' installed then you can still tweak which system components are able to wake the machine up in /proc/acpi/wakeup but it's very cryptic to use. Can you provide output from 'lspci' and a copy of your /proc/acpi/wakeup file? ** Summary changed: - Blanked screen doesn't wake up after locking + Blanked screen doesn't wake up after locking, unless a USB mouse is installed ** Package changed: gnome-shell (Ubuntu) => linux (Ubuntu) ** Summary changed: - Blanked screen doesn't wake up after locking, unless a USB mouse is installed + [Lenovo ThinkPad E580] Blanked screen doesn't wake up after locking, unless a USB mouse is installed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1977977 Title: [Lenovo ThinkPad E580] Blanked screen doesn't wake up after locking, unless a USB mouse is installed Status in linux package in Ubuntu: Incomplete Bug description: After I lock my screen and let it blank, moving the mouse or pressing any key on the keyboard won't wake it up.
