upgrade Ubuntu 14.04.5

The Ubuntu Team has announced the release of Ubuntu 14.04.5 LTS. It’s the fifth and final point release that includes new hardware enablement stack (HWE) from Ubuntu 16.04 LTS.

The Ubuntu team is pleased to announce the release of Ubuntu 14.04.5 LTS (Long-Term Support) for its Desktop, Server, Cloud, and Core products, as well as other flavours of Ubuntu with long-term support.

We have expanded our hardware enablement offering since 12.04, and with 14.04.5, this point release contains an updated kernel and X stack for new installations to support new hardware across all our supported architectures, not just x86.

As usual, this point release includes many updates, and updated installation media has been provided so that fewer updates will need to be downloaded after installation. These include security updates and corrections for other high-impact bugs, with a focus on maintaining stability and compatibility with Ubuntu 14.04 LTS.

Upgrade to Ubuntu 14.04.5:

Ubuntu 14.04 users can easily upgrade to the 14.04.5 point release by running a regular system update via Software Updater.

Or run the commands in terminal:

sudo apt-get update && sudo apt-get upgrade

Note that the updated hardware enablement stack, Kernel 4.4 and X graphics stack from 16.04, will be available through the update only for those who installed Ubuntu 14.04 using the 14.04.2 or newer disc image.

Those who installed Ubuntu 14.04 from the original or 14.04.1 disc image will keep the original Trusty stack. Anyone wishing to opt into the new Kernel and X graphics stack may do so by running the command below in terminal:

sudo apt-get install --install-recommends linux-generic-lts-xenial xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial libwayland-egl1-mesa-lts-xenial

For Sever edition, run this command instead:

sudo apt-get install --install-recommends linux-generic-lts-xenial

[Quick Tip] Enable Telnet Service in Ubuntu 14.04

Last updated: December 20, 2014

Ubuntu-tips

This is quick tutorial that shows you how to install and setup a Telnet server in Ubuntu 14.04 LTS.

TELNET (TELetype NETwork) is a network protocol used on the Internet or local area network LAN connections. It allows one computer to access a command-line interface on a remote host.

Telnet is insecure because the communication is not encrypted, your password and all other data will be transmitted as clear text. If possible avoid Telnet, and use Secure Shell (SSH) instead.

If you really want to enable the Telnet in Ubuntu, just run the command below in text console (terminal) to install Telnet server:

sudo apt-get install xinetd telnetd

Install Telnet Server in Ubuntu

The Telnet service is started automatically once the installation is done. And you can either run telnet serverip or use a Telnet client (PuTTy, SecureCRT, etc.) to access this server.

Telnet Login

To change the port (default is 23), edit the /etc/services file with your favorite text editor. Find out and change the number in the line below:

telnet        23/tcp 

To apply changes, you have to restart the service by running the command below:

sudo /etc/init.d/xinetd restart

More configurations, see this document.

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!

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.
