How To Install and Configure Conky by DarkJediHacker


Install Conky system monitor for Linux and configure it in few basic steps

Conky is one of the most powerful and versatile system monitors for Linux desktops. It allows you to monitor and display all the information about your hardware, top processes, network, emails and more. At the moment more than 300 different feature has been built for Conky and searching on the web you always find the perfect feature already developed by someone.

– Installation on Ubuntu:

in Terminal run: sudo apt-get install conky

– Configuration:

In Terminal run: sudo nautilus

Go to File System: /etc/conky/conky.conf

Save a copy of the original conky.conf in another location and open the original file with Gedit Text Editor

First of all change: own_window yes to own_window no

Choose your preferred alignment (some samples below…):
alignment top_right
alignment middle_right
alignment bottom_right

Play with: update_interval 1.0
and change the interval value till you find the right ratio to obtain the best speed for you (in my case it was 0.80).

Add this line to eliminate any flickering:
double_buffer yes
but, on some computers, all the icon on your desktop will be hidden and you need to use (move) the mouse to discover them if you will not add this parameter: own_window_type normal

Add, as last line (or in other position if you prefer):
${color red} ${cpugraph} to have a clear graph about cpu (obviously you can choose the color you prefer)

For automatic start of Conky at startup, please follow the following instructions:
Run Startup Applications in System –> Preferences
Click on Add and save after updating the following instructions
Name: Conky
Command: /usr/bin/conky

Restart Ubuntu to check your new Conky “applet”

Find online some pre-compiled Conky configuration files, searching, for example, on:

Rediscover Prism by Mozilla (Ubuntu, MAC and Windows tips)

In 2007, when Prism was launched, there were some enthusiastic reviews about this application. Then the widget era began and Prism popularity decreased. Anyway, Prism is still a powerful application for all that people who desire to run their more often used web application saving RAM and CPU resources. Prism, based on XULRunner, is multi platform, easy to use and very flexible. To use it on Ubuntu you can launch the Terminal and type:

sudo apt-get install prism

or using the Synaptics Package Manager (System —> Administration —> Synaptics Package Manager). Then go to Applications —> Internet —> Prism and a small windows appears. Now, fill in all the required information: the web application URL, the name you prefer, settings and do not forget to click on the Desktop shortcut option. At this point you will find a new rough icon on your Desktop with the name you chose. The first time you use it, with the right mouse button click on it and go to Properties —> Permissions and Allow executing file as program. If you want to change the icon you have to click on it (with the right mouse button), go to Properties —> Basic and choose your favorite icon clicking the icon on the upper left corner. If all are steps are annoying for you, it is possible to use Prism as add-on for Firefox. In this case, on Firefox, go to Tools —> Add-ons —> Get Add-ons and type Prism on the search bar. You will install Prism as a simple add-on for Firefox. Now, you can automatically generate a Prism application just clicking on Tools —> Convert Website to  Application when you are in the web application page.

On Windows or MAC we suggest to download the standalone package directly from the official web page or install Prism as Firefox add-on following the same steps we described for Ubuntu. If you use the Prism standalone package you have to decompress it in your favorite location. For Windows users: when you set up a new Prism application, try the tray menu option but do not forget to click on the Desktop shortcut or you will not be able to find again the application after you close it.

In my experience, Prism is really useful with all the Google web applications, with Zoho services and Pandora. Try and enjoy it! AddThis mp3 link

How to manage podcast and RSS reader on Firefox!

This week, in our Linux Page (in Spanish), we posted some lines about editing and changing the feed/podcast reader on Firefox when you have previously chosen a specific program to automatically subscribe to podcasts. If you are using Firefox 3.5 on Linux, you can simply go to Edit -> Preferences and type Feed in the search bar. At this point you have a button menu with all the different options; we suggest to select the  Preview in Firefox one. If you have an older version of Firefox that does not allow you to follow the above path (or for some reason, by default, you prefer the most difficult way) you have to open a new Tab and type about:config in it. After a brief warning message you can type Feed in the location bar and find the browser.feeds.handler line. At this point it is necessary to change the value field to Ask and next time you will decide to subscribe a podcast you will free to choose your favourite program. We hope this few lines could be useful and easy to execute for you all! AddThis mp3 link

How to repair a bad upgrade on Ubuntu!

This week, in our Linux Page (in Spanish) we posted some tips about repairing a bad Linux upgrade.  In fact, it is rare but sometimes, unfortunately, it happens. I mean one or more error during an upgrade installation on Ubuntu. In my case the problem was caused by a blackout and a battery which did not worked properly. When I restarted the PC it worked only in text mode and it asked me the login and the password to enter into the Ubuntu root mode. Obviously, as usual, I typed the requested data and then, after reading how to solve similar problems on internet, I decided to go forward with sudo apt-get update. At this point Ubuntu advised me that something had been wrong during the last update and suggested to try with sudo dpkg –configure -a.  I followed the suggestions and I concluded the “repair session” with  sudo apt-get upgrade –fix-broken. Fifteen minutes later and after rebooting all the “bad upgrade” problems were solved. Recommended! Bookmark this page! mp3 link
