Post Install

Once installed set shortcut key to access LightPad.

  • System -> Preferences -> Hardware -> Keyboard Shortcuts > click Add
  • Name: LightPad
  • Command: com.github.libredeb.lightpad

Now assign it a shortcut key, such as CTRL+SPACE.

Note: Some themes don't have the 'application-default-icon'. LightPad needs to have this icon, so please download it from the elementary_os/icons pack and execute the following commands:

# cp application-default-icon.svg /usr/share/icons/hicolor/scalable/apps/
# gtk-update-icon-cache /usr/share/icons/hicolor

Dynamic Background (optional feature)

LighPad added a new feature, now you can use a custom background of your choice. You can add any wallpaper or image strictly under some of the following path/files and lightpad will use them (prioritizing the JPG format):

$HOME/.lightpad/background.jpg

$HOME/.lightpad/background.png

Blacklist File (optional feature)

Another new added functionality, is the ability to hide applications using a blacklist file. In the file:

$HOME/.lightpad/blacklist

You must add line by line the full name of the binaries of the applications you want to hide in LightPad. For example:

nautilus
rhythmbox
gnome-screenshot
gnome-terminal
firefox
htop
/usr/bin/gparted
/usr/bin/vlc

These lines appear in the .desktop files located in /usr/share/applications as the value of the Exec= tag.
