i3lock is a fantastic lockscreen for tiling window managers.
If you are using a tiling window manager within a public space you need to add a lockscreen. I have one machine that I take with me to a public space. Its secure enough that I can leave it, but not secure enough that I want to leave it unlocked. So when I need to leave it behind for the restroom I need to lock it up.
paru -S i3lock # or apt install i3lock
Now that you have i3lock installed lets lock that screen.
# lock it with a pure white flashbang i3lock # lock it with a black background i3lock -c 000000 # lock it with a custom color i3lock -c 2e1330 # lock it with a wallpaper i3lock -c 000000 ~/Pictures/Wallpapers/mywallpaper.png
You can use your window manager or something more generic like xbindkeys to set
a hotkey. This way you don't have to open a terminal and type out the command
every time you leave your desk. You can just press something like SUPER+L
like you would on other OS's.
Fancy #
If you like it a bit fancier, you can use i3lock-fancy, it can blur,
pixelate, and greyscale your current screen. I did not really like this
because you can still tell what is going on the screen. It's probably secure
enough and looks better, but I went with regular i3lock.
paru -S i3lock-fancy-git # or apt install i3lock-fancy
