Conky

I've found Conky, first for my desktop, and then I installed it on the Z. This utility can present a lot of information to the desktop, such as CPU usage, disk usage, battery levels, wifi signal strength etc. It uses a config file in the home directory (~/.conkyrc). Here's my conkyrc file.

I also wrote this script (/bin/apmStat.sh) to report the battery status.
