### About

Most of i3lock wrapper scripts out there takes an image, adds some effect and locks the screen
adding effects, overall experience doesn't feel natural given delay of 2-3 seconds.
Who would like a delay of 2-3 seconds while locking screen?

So betterlockscreen was my attempt to solve this problem, as we dont need to change lockscreen background frequently
this script caches images with effect so overall experience is simple and as fast as native i3lock.

### How it works

The script takes image adds various effects and caches those images in special directory and then uses those
images as lockscreen background depending on argument provided by user.

### Requirements

> Note: Make sure your system has all dependencies satisfied

- [i3lock-color](https://github.com/PandorasFox/i3lock-color) - i3lock fork with additional features( >= 2.11-c )
- [imagemagick](https://www.imagemagick.org/script/index.php) - To apply effects to images
- [xdpyinfo](https://www.x.org/archive/X11R7.7/doc/man/man1/xdpyinfo.1.xhtml), [xrandr](https://www.x.org/wiki/Projects/XRandR/), [bc](https://www.gnu.org/software/bc/) and [feh](https://feh.finalrewind.org/) - To find screen resolution, set custom blur level and wallpaper handling.

### Installation

> manual installation

```sh
git clone https://github.com/pavanjadhaw/betterlockscreen
cd betterlockscreen
cp betterlockscreen ~/.local/bin
```

Usage examples:

betterlockscreen -u ~/Pictures/Forests.png # caches given image
betterlockscreen -u ~/Pictures             # caches random image from ~/Pictures directory

2. Custom resolution and blur range
betterlockscreen -u path/to/directory -r 1920x1080 -b 0.5

3. Lockscreen
betterlockscreen -l dim                    # lockscreen with dim effect

4. Lockscreen with custom text
betterlockscreen -l dim -t "custom lockscreen text"

5. Set desktop background
betterlockscreen -w blur                   # set desktop background with blur effect
```

### Set desktop background on startup

Add this line to `.xinitrc`.

```sh
# set desktop background with custom effect
betterlockscreen -w dim

# Alternative (set last used background)
source ~/.fehbg
```

#### i3wm

Add this line to `~/.config/i3/config`

```sh
# set desktop background with custom effect
exec --no-startup-id betterlockscreen -w dim

# Alternative (set last used background)
exec --no-startup-id source ~/.fehbg
```

### Keybindings

### Lockscreen when suspended(systemd service)

# move service file to proper dir (the aur package does this for you)
cp betterlockscreen@.service /etc/systemd/system/

# enable systemd service
systemctl enable betterlockscreen@$USER

# disable systemd service
systemctl disable betterlockscreen@$USER


# Note: Now you can call systemctl suspend to suspend your system
# and betterlockscreen service will be activated
# so when your system wakes your screen will be locked.
