# i3wm Transparent Lock screen.

# Warning: If executed multiple times, unlock isn't possible anymore, use with caution!

## Description
Block computer for input, but remain graphical output as usual.
Can be used for example to watch a movie on your laptop but forbid any input during that.

## Downside
Not tested thouroughly yet, and only tested on Debian 9
probably won't work if you already use Compton

## Instructions

### Install required programs
sudo apt install compton


### Extend your i3 config
Add (depending on what you want) the following lines to your i3 config at `~/.config/i3/config`

- ```bindsym $mod+m exec ~/.config/i3/lock_transparent.sh```

### Create the script that locks the screen

Create file `~/.config/i3/lock_transparent.sh` with the following contents:
```bash
#!/bin/bash

compton --config ~/.config/compton/compton.conf -f &
i3lock_standard -n
pkill compton
```
execute `chmod +x ~/.config/i3/lock_transparent.sh` to make the script executable

### Compton config
Create file `~/.config/compton/compton.conf` with the following contents:

```
mark-ovredir-focused = true;
inactive-opacity = 0.7;
opacity-rule = [ "0:name *= 'i3lock'" ];
```

might need to restart or login again, not sure
