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 Ubuntu Desktop Bugs, which is subscribed to gnome-shell 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1977977/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
