There are lots of programs that help us to monitor our personal computer. They provide us with memory consumption, cpu usage, network statistics and lots more. In this article I’m going to introduce gkrellm. I’ve always had gkrellm running in every desktop linux. It’s very useful and provides essential information in real time. Installing gkrellm is just very easy, type:sudo apt-get install gkrellm

to run it, type

gkrellm &

and you’ll get several info about your computer in real time.

Gkrellm supports themes, so the app can have several appearances. I always use the “invisible” theme, which is a transparent theme, so you can see the background. Very cool. To install a new theme (Ubuntu) go to

http://www.muhri.net/gkrellm/

and download the theme you like. Most of the themes come gzipped. Once you download the theme to your home directory, ungzipp it and move the whole directory to ~/.gkrellm2/themes.

When you install RealPlayer in Ubuntu Edgy Eft, it will install not only the player but also the firefox plugins. There’s a problem, though. Firefox is preconfigured to play real audio streams with totem. To use the real player plugin you must remove the totem plugin responsible to play these real audio streams. Just go to the firefox plugins directory located on:/usr/lib/mozilla-firefox/plugins

and remove

libtotem-complex-plugin.so

libtotem-complex-plugin.xpt

type:

sudo rm libtotem-complex-plugin.*

and happy listening with realplayer plugin for Firefox 2

Note:

You can see why totem is responsible to play realaudio streams by typiing in the firefox url bar:

about:plugins

and if you try to play any real audio stream by means of firefox plugins, firefox will try to open totem and totem will complain saying that it can’t open a stream via the rstp protocol.

k3b cannot deal with mp3 files by default in Ubuntu Edgy Eft.
If you need to produce an audio cd by adding mp3 files with k3b, you’ll need to install the following package:

sudo apt-get install libk3b2-mp3

and you are done!!
