Includes Colour factory plugin, Gkey viewer plugin, ip chicken plugin, Skype plugin, Teamspeak 2 and 3 plugin.
LCDHOST
LCDHost is a compositing plugin manager for secondary output devices. It’s primarily useful for Logitech G19 owners, but it’ll work with Z10, G13 and G15 devices too. It uses a plugin architecture for drivers (for output devices) and plugins (to render different pieces of data), so it can be extended to support pretty much any device or piece of software.
I’ve just written an applet for the Logitech G19s keyboard (and maybe others). It displays the names of functions assigned to the keyboard’s G keys on the keyboard’s LCD. The display is updated whenever the active keyboard profile or M-key mode is changed. It’s free; get it from http://catplace.net/gondwana/gassignments.shtml.
I made this layout to work with Aida64
