While LCDd only offers the functionality of displaying text on a display, lcdproc actually retrieves data worth displaying.
lcdproc gets its information from the /proc filesystem.
lcdproc can connect to an LCDproc server either on the local system or on a remote system as long as it is reachable. It extracts the same statistics regardless of where it sends this information. The statistics it gathers include CPU utilization, memory utilization, disk utilization, network utilization, system uptime, time, and date, and so on. It displays this information in assorted ways, and can be tailored to taste.
