Download and extract release tarball for your CPU architecture (pick the right link from the list above):

curl -sSLO https://github.com/jirutka/zzz/releases/download/v0.1.1/zzz-0.1.1-x86_64-unknown-linux.tar.gz
curl -sSL https://github.com/jirutka/zzz/releases/download/v0.1.1/checksums.txt | sha256sum -c --ignore-missing

zzz's Issues

Call `sync` before suspend

Call it directly from zzz or add a default hook script?

unable to start locker 'quickly' enough after resume

I have a script that runs a locker (swaylock) on resume, and the entire desktop (sway) is visible on resume for ~0.5 seconds or so before the locker app kicks in. I'm not sure if this is a zzz 'problem' or something else...

I've tried running the locker app both ways:

case $1/$2 in
        pre/*)
                sudo -u user WAYLAND_DISPLAY=wayland-1 XDG_RUNTIME_DIR=/run/user/1000 swaylock -c 000000 &
                ;;
esac

and:

case $1/$2 in
        post/*)
                sudo -u user WAYLAND_DISPLAY=wayland-1 XDG_RUNTIME_DIR=/run/user/1000 swaylock -c 000000
                ;;
esac

Do you know of some better way to handle this that doesn't result in the desktop being visible on resume?
