I use LightDM with awesome-wm.

To lock screen I use command dm-tool lock. Most of the time it works fine but if after issuing the session lock command I switch to another tty and then go back, session unlocks by itself. /etc/lightdm/lightdm.conf is set to all defaults. How can I fix this behavior?


  • Linux 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u2 (2017-06-26)
  • awesome v4.0
  • lightdm 1.18.3-1

EDIT

Output of the systemctl status lightdm.service command after a couple of locks

CGroup: /system.slice/lightdm.service
           ├─ 931 /usr/sbin/lightdm
           ├─ 941 /usr/lib/xorg/Xorg :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
           ├─1754 /usr/lib/xorg/Xorg :1 -seat seat0 -auth /var/run/lightdm/root/:1 -nolisten tcp vt8 -novtswitch
           ├─1794 lightdm --session-child 15 24
           ├─2137 lightdm --session-child 27 30
           ├─2192 lightdm --session-child 31 34
           ├─2224 lightdm --session-child 35 38
           └─2304 lightdm --session-child 15 20

Finally found a solution here. light-locker needs to be running for dm-tool lock to work correctly.
