Simple X11 live wallpaper:
- uses about 3% CPU (single core)
- does not draw directly on the root window
- no Xinerama, EWMH nor compositor required
- Xlib
- cairo
To build and install, just run:
sudo make install
To configure, edit config.h and recompile.
Then, run the command drop to start drop.
If you want to tinker with the drawing, make sure to pass whole numbers to all the cairo functions, so that they can just call the underlying Xlib functions without compositing. This reduces CPU usage from 50% to 3% ☺.
