Public bug reported:
When suspending my freshly installed 20.04.1 system I noticed that on waking a
password is not required. lightdm does not have locking enabled on suspend. A
workaround I found from pszafer
on archlinux blog.
Quoted below:
create lockscreen.sh file somewhere in your home directory with:
#!/bin/sh
XDG_SEAT_PATH="/org/freedesktop/DisplayManager/Seat0" dm-tool lock
- I've prefer just for sure creating dmlock.service file in home dir and create
symlink to /etc/systemd/system.
File has to be in /etc/systemd/system/dmlock.service
[Unit]
Description=DM Lock before sleep
Before=sleep.target
[Service]
ExecStart=/home/user/dir/lockscreen.sh
[Install]
WantedBy=sleep.target
For your needs, you probably need hibernate.target.
Next run following commands:
systemctl daemon-reload
systemctl enable dmlock.service
Just for sure it is working you could run:
systemctl list-unit-files
systemctl start dmlock.service
Hope it helps you a little
