How to install Unity 6.x backports to Ubuntu 12.04 LTS (Precise)

Unity 6.x (included by default in Ubuntu 12.10 Quantal) features performance improvements and new features on the Unity 3D user-interface as several bug fixes which enhances user experience while using Ubuntu desktop. Besides that, the backport also improve the performance of low-end 3d cards when rendering unity animations.

sudo apt-get update
sudo aptitude remove unity-lens-applications
sudo aptitude install unity
wget http://ppa.launchpad.net/benkai/precise-unity-backport/ubuntu/pool/main/u/unity-lens-applications/unity-lens-applications_6.4.0-0ubuntu2_amd64.deb or
wget http://ppa.launchpad.net/benkai/precise-unity-backport/ubuntu/pool/main/u/unity-lens-applications/unity-lens-applications_6.4.0-0ubuntu2_i386.deb
sudo dpkg -i unity-lens-applications_6.4.0-0ubuntu2_*.deb
[/bash]

Note:
The unity backport may cause stability issues with Nouveau (nVidia Accelerated Open Source video driver). Those who are using nVidia cards are advised to use nVidia blob binary drivers.

How to remove Amazon Shopping search result from Unity

Hi there, Ubuntu 12.10 Quantal Quetzal is out! However the Dash search functionality includes shopping results retrieved from the internet (namely Amazon), which I personally found annoying.

In order to remove that, just run this command:

[bash]
sudo apt-get remove unity-lens-shopping
[/bash]

This will remove online shopping search suggestions. Your mile may vary, but from my point of view, it does speed-up search result.

Compact Grub and Remote Login menu: New features that I love in Ubuntu 12.10 Quantal Quetzal

Those who are keeping up with the updates knows that Ubuntu 12.10 Quantal Quetzal has been released yesterday!

However now I’m going to share two great features that I like about Ubuntu 12.10 Quantal Quetzal.

#1. New GRUB menu that hides old kernel after updates!

Now, GRUB menu always display “Ubuntu” with each kernel update. All previous kernels are grouped together under the “Advanced options for Ubuntu”.

So you get:

Instead of:

This will keep the computer from listing too many kernels on the boot menu, which is messy in itself.

#2. Remote Login option!

Ubuntu Quantal Quetzal allows users to login remotely to Remote Desktop Protocol (RDP) server right from Ubuntu Greeter.

Other Features worth mentioning

  • Linux kernel 3.5
  • LibreOffice 3.6.1.2, featuring menu that can be integrated to Unity menu.

Backup your Gmail account in Ubuntu Linux with gmvault

This is a follow-up of my previous post “What to do when your Google disabled your Gmail account?“.

Here’s how to download all emails from your GMail account with Gmvault:

Download and setting up gmvault

1. First you need to install python-pip
[bash]
sudo apt-get install python-pip
[/bash]

2. Then using ‘pip’, install gmvault
[bash]
sudo pip install gmvault
[/bash]

3. Finally you can sync and backup GMail accounts with ‘gmvault
[bash]
gmvault sync your_username @ gmail.com
[/bash]

4. gmvault will ask you to authenticate yourselves with GMail, and after that, the syncronization process starts. gmvault stores all the gmail backup in the ‘gmvault-db‘ directory.

p/s: Some users encounters error telling that the “All Mail folder is not visible”. You can enable All Mail folder visibility by checking the “Show in IMAP” box in Settings->Labels. Also, IMAP access should also be enabled for this to work.

p/s 2: It might not be obvious right now why you need to backup your emails when Gmail has gigabytes of storage. But according to Gmail discussions group, Google can and might disable access to all of its services, locking the users out from their emails forever.

Ubuntu 12.04 LTS Precise Pangolin Latest New Features

The latest Ubuntu 12.04 LTS is going to be released in (28 April 2012), that is less than a week! The latest features of Precise Pangolin are:

1. Linux Kernel
Ubuntu 12.04 will use a kernel based on the 3.2.12 upstream Linux kernel, which include a patch that makes Linux powered laptop consumes more efficiently

2. HUD – Intelligent search feature in Ubuntu 12.04
Stands for Heads-up Display, HUD can be used to search for items in the menu bar in most applications. For example, if you are looking for a particular menu (or functionality) in GIMP, but can’t quite recall its position, you can use HUD to search it. Pictured here here is an attempt to search for ‘Blur’ filter for GIMP.

Ubuntu HUD

Currently HUD only works with application that supported Global menu, which means you can’t use it in LibreOffice.

3. Rhythmbox replaced Bansee as the default multimedia player
A decision came during the last Ubuntu Developer Summit (UDS). This move is connected to the new community decision to remove Mono and any application that depends on it from the default installation.

Another casualty is Tomboy note-taking application and gbrainy (game) which also depends on Monoi

**personally, I find depending on Mono application could be problematic, moreover those applications aren’t taking advantage of the ‘portability’ of the .NET platforms (It can’t be used on Microsoft Windows either, not without extensive hacking). So what’s the use of including Mono application on Ubuntu, except for bloating distros?

4. Global Privacy Settings
Ubuntu 12.04 LTS features “Privacy” option in the System Settings screen. The new Privacy Menu gives users the option of turning off History recording for users activities with a click of a menu.

Privacy 1

Privacy 2

Users may also disable activity recording for a specific group of applications (Instant Messaging, Web browsing, Office Documents, Emails and Multimedia), note that this option *MAY* only work on application that comes with Ubuntu default-installation.

5. Ubuntu *.ISO installer will exceed CD-ROM size
CD-ROM was used as installers on computer platform since 1994, back then the 650MB storage was larger than the average hdd capacity of around 320MB-500MB. The practice of releasing CD-sized ISO have since followed Linux distro for years, well after DVD drive and DVD-writers have become common.

Starting with Ubuntu Precise Pangolin (12.04 LTS), Ubuntu *.iso sizes will not fit CD-ROM anymore. it’s ISO size is estimated to be around 750MB to 800MB. Users may burn the ISO on DVD or use utilities such as UNetBootin to create bootable USB Drive.

My Thoughts
I think Ubuntu is going strong on this release with vast improvements on the usability, especially on the aspect of the UI user-friendliness to those who are new to GNU/Linux. However, I still thinks that Unity UI (and to the extend, the Ubuntu Software Center) is VERY SLOW even when running on a modern system as it took about 10 seconds to load Ubuntu Software Center.

Frankly, I think Ubuntu and the general GNU/Linux desktop community should improve the perceived latency of its UI first in order to persuade people to use open source operating system.
