What is it?

This is a keyboard leds plugin (based on sample plugin) for the Xfce panel.

Installation

You should have

• xfce4-dev-tools
• libxfce4panel-2.0-dev
• libxfce4ui-2-dev

Then run

./autogen.sh
./configure --prefix=/usr
sudo make install

On some distros you need to specify plugin directories by yourself like this

./configure --prefix=/usr --libdir=/usr/lib/x86_64-linux-gnu

If ScrollLock key does not work, you can enable it with this command

xmodmap -e 'add mod3 = Scroll_Lock'
