Ubuntu 14.10 logo

Ubuntu 14.10 Utopic Unicorn finally reached the end of its life on July 23, 2015. No more package updates will be accepted to 14.10. That means 14.10 users won’t get latest software (e.g, Firefox, Thunderbird), security notices/fixes through Software Updater. And Launchpad PPAs will no longer update for 14.10.

Ubuntu 14.10 was released 9 months ago, on October 23, 2014. As a non-LTS release, it has a 9-month month support cycle and, as such, the support reached the end of life on last Thursday. Users of Ubuntu 14.10 may upgrade to Ubuntu 15.04 (ends on January 2016), or install Ubuntu 14.04 LTS which has a 5-year support (until 2019).

To upgrade to Ubuntu 15.04, see:

https://help.ubuntu.com/community/VividUpgrades

To download Ubuntu 14.04 LTS, go to:

http://releases.ubuntu.com/trusty/

Here’s the support period of the current Ubuntu releases includes the next Ubuntu 15.10 Wily:

Version Code name Release Date End of Life Date
Ubuntu 15.10 Wily Werewolf October 22, 2015 July, 2016
Ubuntu 15.04 Vivid Vervet April 23, 2015 January 2016
Ubuntu 14.04 LTS Trusty Tahr April 17, 2014 April, 2019
Ubuntu 12.04 LTS Precise Pangolin April 26, 2012 April, 2017

Virtualbox repository

Oracle finally made the Virtualbox binary packages for Ubuntu 14.10 Utopic available in its official Linux repository. Which means running regular system updates via Software Updater will keep your Virtualbox release always up-to-date.

While Ubuntu 14.10 repositories provide the Virtualbox 4.3.18, the latest has reached the version 4.3.20. For the changelog, see the web page.

Virtualbox 4.3 in Ubuntu 14.10

How to Add Virtualbox Repository in Ubuntu:

Open terminal from the Unity Dash or just press Ctrl+Alt+T on keyboard. When it opens, paste the command below into terminal and run to get the key:

wget -q -O - http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc | sudo apt-key add -

Type in your user password when it asks. Then run command to add the vbox repository for Ubuntu 14.10:

sudo sh -c 'echo "deb http://download.virtualbox.org/virtualbox/debian utopic non-free contrib" >> /etc/apt/sources.list.d/virtualbox.org.list'

Now install Vbox 4.3 via your package manager after checking for updates. Or just run commands below one by one:

sudo apt-get update

sudo apt-get install virtualbox-4.3

Finally keep your system up-to-date by running regular system updates, which also keep your Virutalbox 4.3 series up-to-date.

Speed Up the Unity Dash response

This quick tutorial shows how to improve your Ubuntu experience by speeding up the Unity Dash (search utility) response in Ubuntu 14.10 or Ubuntu 14.04.

The Unity Dash

1. Remove undesired search results

By default, the Dash displays Unity lens, scopes, Amazon online search results, and records file and application usage. You can disable some of them via below tips:

  • Disable online search results:

    Launch System Settings and go to Security & Privacy, under “Search” tab turn off the switch which says “When searching in the Dash: include online search results”

    Disable Online Search Results

  • Stop recording file and app usage:

    Also launch System Settings and go to Security & Privacy, under “Files & Applications” tab first clear records and then turn off the switch:

    Stop recording file and app usage

  • Remove unwanted Unity lens, scopes:

    Open Ubuntu Software Center and search for unity-scope. In the results, check the information of installed scopes and remove the scopes you don’t need.

    unity-scopes

    Do same to Unity lens by searching unity-lens.

2. Reduce Graphics Settings.

First click the link below to bring up Ubuntu Software Center and click install Compiz Config Settings Manager.

Click to install CCSM

Then launch CCSM from the Unity Dash and do below changes:

  • Go to Ubuntu Unity Plugin page under the Desktop category. Select No Blur from the drop-down box for Dash Blur.

    No Dash Blur

  • Go back and then go to OpenGL settings page under General category. Select Fast from the drop-down box for Texture Filter.

    texure-filter-fast

    Note that this change would affect the whole Ubuntu System graphics and not Unity alone.

To apply all the changes, restart your computer. Enjoy!

Install Wine Ubuntu 14.10

Run Windows only applications in Ubuntu? Well, here’s how to install the latest Wine development release with bug fixes and new features in Ubuntu 14.10 Utopic.

For those who don’t know about Wine:

Wine (originally an acronym for “Wine Is Not an Emulator”) is a compatibility layer capable of running Windows applications on several POSIX-compliant operating systems, such as Linux, Mac OSX, & BSD. Instead of simulating internal Windows logic like a virtual machine or emulator, Wine translates Windows API calls into POSIX calls on-the-fly, eliminating the performance and memory penalties of other methods and allowing you to cleanly integrate Windows applications into your desktop.

Wine began in 1993 under the initial coordination of Bob Amstadt as a way to support running Windows 3.1 programs on Linux. Very early on, leadership over Wine’s development passed to Alexandre Julliard, who has managed the project ever since. Over the years, as the Windows API and applications have evolved to take advantage of new hardware and software, Wine has adapted to support new features, all while being ported to other OSes, becoming more stable, and providing a better user-experience.

An ambitious project by definition, work on Wine would steadily continue for 15 years before the program finally reached v1.0, the first stable release, in 2008. Several releases later, Wine is still under active development today, and although there is more work to be done, millions of people are estimated to use Wine to run their Windows software on the OS of their choice.

Open Windows EXE file with Wine

open Windows .exe file directly with Wine

Install Wine Development in Ubuntu:

While Ubuntu repositories provide the stable Wine 1.6 release, the latest development Wine 1.7 with bug fixes and new supports is available in Wine official PPA. So far, Ubuntu 14.04 and Ubuntu 14.10 are supported.

To add the PPA, press Ctrl+Alt+T to open terminal. When it opens, paste the command below and hit Enter to run:

sudo add-apt-repository ppa:ubuntu-wine/ppa

Type in your user password when it asks.

After added the PPA, install Wine1.7 from Synaptic Package Manger after clicking Reload button. Or just run the commands below in terminal:

sudo apt-get update

sudo apt-get install wine1.7

That’s it.

When a future release is out and made into the PPA, running regular system update via Software Updates will automatically upgrade the wine1.7 to the latest.

Enable Hibernate Option in Ubuntu 14.10 Unity

Last updated: October 24, 2014

Ubuntu 14.10 Hibernate

The Hibernate option is available in Beta and Alpha releases of Ubuntu 14.10, but the final release removed this option in the Unity desktop.

This quick guide is going to show you how to re-enable this feature so that you can hibernate your machine from the shutdown menu (top-right gear button).

hibernate ubuntu 14.10

1. Before getting started, you may run command below in terminal (Ctrl+Alt+T) to test if hibernate works in your case:

sudo pm-hibernate

After you computer turns off, switch it back on. Did your open applications re-open? If hibernate doesn’t work, check if your swap partition is at least as large as your available RAM.

2. To re-enable hibernate, run command below to edit the configuration file:

sudo nano /var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla

When the file opens in the terminal window, scroll down to find out the section started as:

“[Disable hibernate by default in upower]” and “[Disable hibernate by default in logind]”

Change the value of ResultActive to yes in both.

enable-hibernate-conf

3. To save the changes, press Ctrl+X and type y and finally hit Enter.

When everything’s done, restart your computer.

Tips:

1. If previous steps do not work for you, replace the command in step 2 with:

sudo nano /etc/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla

2. Thanks to Cruz, you can add below lines into the configuration file to make Hibernate work for multiple users:

[Re-enable hibernate for multiple users by default in logind]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate-multiple-sessions
ResultActive=yes

3. If you want to hibernate your laptop when lid is closed, run command to edit the configuration file:

sudo nano /etc/systemd/logind.conf

Add HandleLidSwitch=hibernate as a new line into the end and save the file. It will work at next boot.

Emacs 24.4 in Ubuntu 14.04

How to Install Emacs 24.4 in Ubuntu:

At the moment of writing this tutorial, there’s no PPA repository that contains Emacs 24.4. Fortunately, it’s not hard to build it from the source tarball. I’ve done it successfully in 64-bit Ubuntu 14.04 LTS. Below steps will show you how:

1. If have the old Emacs 24.3 installed, you may first remove it from Ubuntu Software Center so that you can install the new version over it.

2. Press Ctrl+Alt+T on keyboard to open terminal, or open it from the Unity Dash.

Open Terminal to run commands

3. Run command below to install the build-essential:

sudo apt-get install build-essential

4. Install the required dependencies:

sudo apt-get build-dep emacs

While the installing process, you’ll be asked to configure the Postfix.

5. Now download Emacs 24.4 from its official FTP download page.

Emacs FTP download Page

6. Extract the source and go into the result folder in terminal:

cd ~/Downloads && tar -xf emacs-24.4.tar.* && cd emacs-24.4

7. Finally compile the package by running commands below one by one.

./configure

make

sudo make install

Once done, you should be able to launch Emacs by running emacs or emacs-24.4 in terminal and lock the shortcut to the Unity Launcher.

To create a launcher for Emacs 24.4. Thanks to Emad Khoury, run command to create a .desktop file and edit it with Gedit text editor:

sudo gedit /usr/share/applications/Emacs-24.desktop

When the file opens, paste below into it and save the file.

[Desktop Entry]
Version=1.0
Name=Emacs-24
Exec=env UBUNTU_MENUPROXY=0 /usr/local/bin/emacs
Terminal=false
Icon=emacs
Type=Application
Categories=IDE
X-Ayatana-Desktop-Shortcuts=NewWindow
[NewWindow Shortcut Group]
Name=New Window
TargetEnvironment=Unity

Depends on where you install Emacs 24, you may replace the value of Exec and Icon to the path to executable and shortcut icon file.

Installing Minecraft in Ubuntu is quite easy. All we need to do is install Java, download and run the .jar executable from its official website.

1.) To get better game experience, you may first install graphics driver for your video card:

  • For Intel graphics, you’re good to go with the default open-source driver.
  • For NVIDIA or AMD graphics, it’s better to use a proprietary video driver. Open Additional Drivers utility from the Unity Dash, select the NVIDIA or AMD driver from the list and install it.

2.) For Java, you can either install OpenJDK Java 7 from Ubuntu Software Center or install Oracle Java from PPA.

To install OpenJDK Java 7, click the button below to bring up Ubuntu Software Center and click the install button.

Click to Install OpenJDK 7

To install Oracle Java, see this post or just run commands below one by one in terminal:

sudo apt-add-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java8-installer

3.) Once Java Runtime is installed, download the Minecraft.jar file from:

Minecraft Download Page

4.) Make the Minecraft.jar file executable.

To do so, right-click on the file in Nautilus browser and go to its Properties windows -> Permissions tab and finally check the box where it says “Allow executing file as program”.
