I made a hotkey for `systemctl suspend` or `systemctl hibernate` in dwm. However after I power my PC back on again, it suspend a second time. This is not an issue of the systemctl command, the same problem with `echo mem > /sys/power/state`. It is also not a dwm problem, same issue with sxhkd on keypress event. However if sxhkd executes the command on key release, it works fine. On Gentoo I didn't have this problem. I used an elogind command because I was using openrc as init system.
I think a keypress event is sent after suspend/hibernate for all the keys pressed before suspend, so the hotkey executes twice.
