Two major problems I have experienced with Ubuntu on a laptops are heating up and battery drainage. Most of the modern day devices have the capability to save power. The drivers installed on the Ubuntu has the capability to do that also. But they are underutilized. This results in the dual problems of heavy battery drain and heating up. These two problems are interrelated and they can be solve together by doing some manual configurations. The following methods were successfully tested in three hp laptops ( The laptops used processors: AMD A10 with ATI dual graphics, i5 with Intel and ATI dual graphics and Dual Core without graphics card). 1)  The first and most important solution to the problem is TLP. (Thanks to my friend who told me about this.)  TLP is an advanced power management tool for Linux. It is a pure command li...

Microsoft Office is my favorite office application. The default LibreOffice in Ubuntu 12.10 lacks a lot of Features available in MS Office. After succesfull installation of Microsoft Office 2007 in Ubuntu 11.10 and 12.04/12.10 , I tried installing Microsoft Office 2010 in 12.10.

There are few changes in the dependencies needed for 201 0 when compared to 20 0 7 . This method works in Ubuntu 13.04, 13.10 and 14.04 as well. This has been tested on both 3 2 and 64 bits successfully . This method is reported to work in Ubuntu derivatives like Mint by users through comment. 1. For 64-bit users first step is to install mesa OpenGL and the 32-bit libraries. For all except 14.04 :   sudo apt-get install mesa-utils mesa-utils-extra libgl1-mesa-glx:i386 libgl1-mesa-dev ia32-libs For Ubuntu 14.04 users t...

To use onion routing in Ubuntu 12.04 you can use either of the following methods:  Method 1 The first option is to download tor browser bundle and extract  it. Tor can be launched by running start-tor-browser script in extracted directory. If permission is denied then run "chmod -R +x * in a terminal to add executable bit to the files. During first run, Stop tor, Set the proxy in vidalia settings and Start tor again. Once the connection is established tor browser will come automatically. This is a tweaked version of firefox. By default, add-ons and other extensions are disabled. The proxy settings and port of privoxy can be found from Edit-> Preferences->Advanced->Network->Settings. You can copy the proxy and port to any application's proxy settings to make it work behind tor. Method 2 1. Vidalia can be installed from the command line or synaptic or USC. I prefer to use the terminal for installation. If privoxy is already installed in the system the...

1. Installing dropbox in Ubuntu 12.04                    Dropbox installation is not as easy for users behind a proxy. Two major problems seen during dropbox installation are: (i) If dropbox is installed from repositories using apt-get or synaptic or usc, usually a screen appears asking for permission everytime we launch dropbox and most of the times it doesnt launch. (ii)Drobox deamon fails to download and install automatically after dropbox installation.                        The dropbox installation can be easily done as follows. Instead of installing dropbox available in repositories go to dropbox website . Download dropbox for ubuntu 64 bit or 32 bit .Now install this by opening in ubuntu software center or using the following commands: sudo dpkg -i sudo apt-get -f install While launching dropbox...

I have successfully installed Microsoft Office 2007 in Ubuntu 12.04.  I installed on both 32 bit and 64 bit machine. The steps are little different for the different architecture.The instruction for installing MS Office in 12.04 has a slight difference from that I earlier explained for Ubuntu 11.10 . Update: This method works in Ubuntu 12.10 as well. This works on Mint 14, XUbuntu 12.04, XUbuntu 12.10, etc also. This method is expected to work on 13.04 and 13.10 but is not tested.
