| First, not hibernate | |
| You actually want to disable hybrid sleep | |
| You may not already know it, but trust me | |
| That's what you want | |
| Okay? Good | |
| Now lets go | |
| First, check that UPower's critical action | |
| is set to "HybridSleep" | |
| File: /etc/UPower/UPower.conf | |
| ... | |
| CriticalPowerAction=HybridSleep | |
| ... | |
| Next, reload the UPower daemon | |
| $ sudo systemctl restart upower | |
| Check that it has taken hold | |
| $ upower -d | grep critical-action | |
| If you don't see "HybridSleep", check that you can HybridSleep | |
| $ gdbus call --system --dest org.freedesktop.login1 --object-path /org/freedesktop/login1 --method org.freedesktop.login1.Manager.CanHybridSleep | |
| You should see ('yes',) | |
| If not, make sure your hybrid-sleep target isn't masked | |
| $ sudo systemctl status hybrid-sleep.target | |
| $ sudo systemctl unmask hybrid-sleep.target | |
| $ sudo systemctl status hybrid-sleep.target | |
| Once upower -d's critical action is HybridSleep | |
| Now, modify the systemd unit for handling | |
| hybrid sleep | |
| $ sudo systemctl edit systemd-hybrid-sleep --full | |
| ... | |
| -ExecStart=/usr/lib/systemd/systemd-sleep hybrid-sleep | |
| +ExecStart=true | |
| ... | |
