I'm going to be installing Ubuntu 8.04 desktop and I need a program, preferably with a GUI, that provides temperature monitoring of all known sensors on my motherboard.

I've heard about lm_sensors, but is there a GUI for it?

Also, is there a hardware info program for Linux that is similar to cpu-z? I'm looking for something that will provide thorough, human readable information. At the least:
-cpu multiplier
-fsb
-memory speed
-memory timings

I've heard of HardwareLiSter, but I looked through a few screenshots and I'm not sure if it has what I want. Does anyone have any recommendations?

Thanks.

As far as lm_sensor GUIs there are several. If you're using Ubuntu, then I assume you're using GNOME. GNOME has panel plugins for lm_sensor outputs (as well as hddtemp). You could also use gkrellm to display lm_sensor information. Conky can also be configured to display sensor output.

I'm not familiar with cpu-z, but there are plenty apps or other ways to get CPU information from a Linux machine. Simply executing cat /proc/cpuinfo will give you info on your cpu.

Thanks I might try out GKrell.
