Conky

Conky is Xorg window system]], which "can display arbitrary information (such as the date, CPU temperature from I2C, MPD info, and anything else you desire) to the root window in X. Conky normally does this by drawing to the root window, however Conky can also be run in windowed mode (though this is not how Conky was meant to be used)."

Configuration
After installing Conky, you may want to create a default configuration as a starting point:

Open the configuration file with a text editor of choice and edit away. Enabling lua syntax highlighting may help you.

Users of modern composited desktop environments will probably want to use conky in own window mode with true transparency:

own_window = true, own_window_class = 'conky', own_window_argb_visual = true, own_window_argb_value = 80, own_window_hints = 'undecorated,below,sticky,skip_taskbar,skip_pager', own_window_colour = '101010', own_window_type = 'desktop'
