TLDR:
➜ ~ cat /etc/systemd/system/stopbt.service
[Unit]
Description=stop bluetooth before hibernation
Before=hibernate.target
[Service]
ExecStart=bluetoothctl power off
[Install]
WantedBy=hibernate.target
➜ ~ cat /etc/systemd/system/startbt.service
[Unit]
Description=start bluetooth after hibernation
After=hibernate.target
[Service]
ExecStart=bluetoothctl power on
[Install]
WantedBy=hibernate.target
systemctl enable stopbt startbt
I had a problem where my bt mouse and keyboard stops working on resume from hibernation. After a couple of days of searching for a solution I came up with above trick. The main idea is to turn off bluetooth power before the hibernation starts and power on it back after resume. I’ve tried another approach that I posted here but it works every other time. My hyposesis is that bt driver gets a corrupted hardware state after resume and even driver reloading doesn’t help, only full restart. It should also for sleep.target as well. I also have a question: is there a standard way to share systemd unit files for easy installation? Is it good practice to create rpm package for such scripts?
