Hello, I want my laptop (Lenovo M30) to not suspend when lid close on AC power. And suspend on battery. I already made these changes: 1. dconf editor -> org -> gnome -> settings daemon -> plugins -> power -> lid-close-ac-action -> lid-close-battery-action 2. sudo vim /etc/systemd/logind.conf find line "#HandleLidSwitch=suspend" Replace line with "HandleLidSwitch=ignore" 3. sudo nano /etc/UPower/UPower.conf set "IgnoreLid" to true Still no use. Laptop suspend when I close the lid. Is it possible to make it work? P.S. It started working normaly anyhow. Thanks.
