I installed Ubuntu 11.04 on one of my systems and I am using the Unity interface. Unity is working quite well so far but I really miss panel applets for net speed, cpu temp, and system monitor.

These applets are useful for viewing quick info. Unlike 10.10, there is no other way to get this info onto the panel or unity launcher. There are solutions like screenlets and conky but they don't feel appropriate for a clean desktop look.

If you know one then please list out any third party indicators with links so that they can be found.

The first time the application is used, run

python /usr/share/stackapplet/stackapplet.py &

So after enabling universe repositories, It can be installed by following command:

But it has bug with adding account so upgrade to 1.5.2 as follows:

sudo add-apt-repository ppa:stackapplet-dev/stackapplet

If you have a laptop or Netbook and want to be able to cool down that chip that's burning your hand and save some battery power this will be useful.

sudo apt-get install indicator-cpufreq

Install via the software center

If you don't use the indicator plugin (say, on Xfce), you can also use this utility in the systray (or notification area).

indicator-cpufreq appears not to work with Ubuntu 12.04 –  Inkayacu May 5 '12 at 16:48
The PPA threw a 404 for me when I tried to add it, but it turns out is was already in the repos for 12.04, so I installed that and it appears to be working just fine. –  Nick DeMayo Jul 15 '12 at 14:15
The PPA is no longer needed, the indicator comes with Ubuntu 12.04. It also does work (but you need to start it manually, such as by typing indicator-cpufreq on a terminal) –  Scott Ritchie Jul 27 '12 at 0:33


Psensor is a tool to monitor hardware temperature that integrates nicely with Unity by using an Unity Launcher counter which displays the enabled temperatures as well as an appindicator that you can use to take a quick look at all available hardware temperatures or cpu usage.

Psensor can monitor:

  • motherboard and CPU temperatures
  • the temperature of Nvidia GPUs
  • experimental ATI/AMD GPUs temperature monitor (not enabled for the Ubuntu PPA as it requires compilation using libatiadlxx)
  • hard disk drives temperature
  • fan speed
  • CPU usage

enter image description here

Plug-ins installation:

sudo apt-get install lm-sensors hddtemp

sudo sensors-detect

sudo service module-init-tools start

Psensor installation:

sudo add-apt-repository ppa:jfi/ppa

sudo apt-get update

sudo apt-get install psensor

this indicator as it seems, according to this bugs.launchpad.net/ubuntu/+source/unity/+bug/720446 that it causes a memory leak in unity. so be aware. –  suli8 May 9 '11 at 3:15
I would love for the way the scaling of the network throughput works to be a user setting. I prefer a fixed scale rather than the indicator scaling up and down as throughput demands. Other than that, interesting. –  mvexel Aug 22 '11 at 4:59
The memory leak bug is when it works in tandem with compiz...so no compiz (which is buggy anyways) equals happy and safe indicator.. :) –  charlie May 8 '13 at 13:08
