Early Preview of Gnome Shell 3.14 On Ubuntu GNOME 14.10

GNOME 3.14 is releasing in September and Ubuntu-GNOME in October, therefore this is an early access to the development versions of both of them. However Ubuntu development releases are quite stable and the same also applies for GNOME, so it should be a very usable system.

Running GNOME in Ubuntu won’t give a genuine GNOME experience and not all things work as supposed to, but on the other hand Ubuntu will give you the best out of Linux desktop the term is wrong in general, meaning easy access to all available software, free and no-free. Something you should keep on mind if you prefer GNOME over Unity is that is recommended to install Ubuntu GNOME and not Ubuntu and install GNOME after. The interplay of the two desktops when we add GNOME PPAs is really bad. Also getting GNOME from official PPAs of Ubuntu, it is a poor GNOME “clone” and additionally it would be an old version too. It isn’t very good idea to make a judgement out of it. It isn’t even a worth to try it like this.

Get latest GNOME On Ubuntu GNOME

That involves three steps. Download Ubuntu GNOME, add PPAs and reboot.

You will need to download one of the daily Ubuntu GNOME images. To burn the ISO you can watch this YouTube guide.

Prefer the 64bit architecture and if you have an UEFI, boot the USB from there. Install as normal and update the system.

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

Every time that upgrade will keep packages back, try dist-upgrade.

sudo apt-get dist-upgrade

Then add the PPAs.

We are going to use the bleeding edge snapshots. Two things.

  1. Read the details on PPAs
  2. You have to know how to use ppa-purge and apt-get

PPA-purge disables a PPA and reverts to the official packages if applicable. The syntax is very simple

sudo ppa-purge the-PPA-to-remove

The PPAs you need to add are:

sudo apt-add-repository ppa:gnome3-team/gnome3
sudo apt-add-repository ppa:gnome3-team/gnome3-staging
sudo apt-add-repository ppa:ricotz/testing

After that, update

sudo apt-get update && sudo apt-get upgrade //or dist-upgrade

You’re done, just reboot!


Overall

GNOME is depended in some degree on GNOME-Software, and GNOME-Software isn’t available in repositories. GNOME Software helps us to create Application-Folders in Shell, makes applications easily discover-able from Shell through a search provider, and more.

ubuntu-software-center

 

In general there are some smaller issues as well (eg theming, gsettings, super+right click, and others), missing software and not all GNOME modules aren’t updated to the latest (yet). Ofcourse this is still an early release (technically not even release!).

For now just a screencast. Open Source and proprietary in perfect harmony with a single click in Ubuntu!

Ubuntu GNOME with the Testing PPAs at the moment has many many bugs concerning GNOME implementation that don’t happen for example in Fedora 21.


A last thing you should know is that GNOME 3.14 is going to bring huge improvements, so it is a worth to update to it.

As a matter of fact is always important to update on the latest desktop releases no matter what Linux desktop you’re using. They all do bring many many improvements that make your life easier. Easier means less nerves -happier 🙂

Introducing Betty, the Siri for the Linux Terminal

Betty is like Siri or Google Now for the command line. Well, sort of. The tool translates plain English into commands: it displays the command it runs and obviously, the command output, in the terminal. It can even speak the command output.

Screenshot from 2014-05-16 14:31:26

Betty’s mission is, according to its GitHub page, to “provide a way to use computers through natural language input“:

“Specifically, the benefit is being able to do things on your computer without leaving the command line or screwing around on the internet trying to find the right command. Betty just works“.

For example, if you can’t remember the exact compress and uncompress commands, you can simply ask Betty to do it:

betty uncompress archive.tar.gz

Of course, the commands supported by Betty at this time is pretty limited since the tool is under two weeks old, but it should improve quite fast since it’s not that hard to add new commands (and there are 17 contributors already).

Betty 0.1.5 supports a wide variety of commands, such as:

count (number of characters in a file, number of words in a directory, etc.);

config (change your name);

datetime (current time, date, etc.);

Find (find in files);

Internet / web queries (download some file, find out what’s the weather like, etc.);

file / directory operations (compress/uncompress files, show file size, change permissions, etc.);

processes;

user commands (what’s my username, real name, ip address, who else is logged in, etc.);

control iTunes and Spotify;

and much more.

A complete list of supported commands is available @ GitHub (under Documentation).

How to install Betty:

1. Install Ruby. In Ubuntu, install it using the following command:

sudo apt-get install ruby

2. Install git and download the latest Betty using the following commands:

sudo apt-get install git

3. And finally, you’ll have to add the path to the “betty/main.rb” file as an alias for “betty” in your ~/.bashrc file. Do this automatically (assuming you’ve downloaded Betty in your home folder!) by using the following commands:

echo “alias betty=\”~/betty/main.rb\”” >> ~/.bashrc
source ~/.bashrc

How to Capture a Screenshot of Your LightDM Login Screen (Unity Greeter) in Ubuntu

This quick tutorial is going to show you how to capture LightDM Unity Greeter, the log in screen, in Ubuntu 14.04 LTS.

Besides installing Ubuntu as a guest OS via Virtualbox or VMware Player, there’s no graphical screenshot tool to capture the log-in screen.

However, there’s simple script can do this job and below picture was taken by this method:

Get the Most from Your Terminal with Tabs and Other Customizations

Modern Linux distributions try to shield users from the complexities of the command-line, but there are times when using a terminal is absolutely necessary. On Ubuntu, the default terminal is the GNOME terminal (“gnome-terminal“). To start it, tap the “Super” key (which is probably the Windows key on your keyboard), type “terminal” and then click on the Terminal icon.

The word terminal comes from a previous era in computing when the connection from a computer ended (terminated) at a character-based workstation. This concept itself comes from the field of electronics where a terminal is the the end of a line where signals are either transmitted or received. Today, the terminal program is a software equivalent of those character-based workstations.

For quick one-line commands, or a quick bit of system configuration, the default terminal settings are more than adequate; however, if you spend any length of time using the terminal, you may find that you want to customize it to better fit your needs.

The simplest customization is to change the dimensions of the terminal window. By default, the terminal window has twenty-four rows with each being eighty characters wide. You can change the size by dragging any of the edges or corners. This can be a bit haphazard, so the terminal program also offers some presets. Click Terminal on the menu bar and choose between 80×24 (the default), 80×43 (a long version of the default), 132×24 (wide) and 132×43 (wide and long).

If you need another terminal session, you can start one from the launcher, or you can right-click inside the terminal window and click “Open Terminal”. If you use the second method, then the current working directory is preserved. If you have several terminal windows open then you may find that your screen is getting a little cluttered. The solution is to open terminal tabs. To open a tab, right-click inside the terminal window and click “Open Tab”. The tabs appear at the top of the window, and the title of the tabs shows the current prompt: A combination of the username, the machine name and the current directory. Tabs can be closed by clicking on the X, by using “Close Tab” from the context menu or by exiting the shell with CTRL-D.

The terminal program also has the concept of a profile. This allows you to set different preferences and remember them in a profile. Each terminal session can use a different profile. To create a profile, select “New Profile …” under the ”’File” menu. To edit a profile’s preferences use ”Profile Preferences” under the Edit menu or right-click and select “Profile Preferences” under the Profiles sub-menu.

Among the preferences are the ability to change the default font and alter the amount of scroll history that is retained. You can also set the background color and make the background semi-transparent!

If you like the tabs on the Ubuntu terminal, then you might also be interested in another terminal program called Terminator. Like the default terminal program, it allows you to open multiple sessions, but rather than using tabs, it allows the terminal windows to be split horizontally or vertically. By splitting the window multiple times, several different terminal sessions can be started.

To install it, use the Ubuntu Software Center or type the following command in a terminal window:

sudo apt-get install terminator

To start the program, tap the “Super” key, type “terminator” and click the Terminator icon. To start another session, right-click inside the terminator window and click “Split Horizontally” or “Split Vertically”. Repeat the process to split another pane and so on.

PPA-Purge: How to Roll Back Major Installations in Ubuntu

Screenshot from 2014-05-11 15:02:54If your helping with testing new features in the development version of ubuntu, or trying out a new Desktop Environment, you will likely encounter installing new packages from a ppa. But what happens when you want to roll back those changes?

Thankfully there is a tool to help called ppa-purge. PPA-purge will uninstall all packages from a specified ppa and downgrade you back to the archive versions. In addition it will disable the ppa so you can’t install packages from it.

Installation

sudo apt-get install ppa-purge

How to use

Simply execute the following line, replace the ppa:NAMEOFPPA with the ppa you wish to purge.

sudo ppa-purge ppa:NAMEOFPPA

I’ll show you a quick example of me removing the HUD ppa:

sudo ppa-purge ppa:unity-team/hudUpdating packages lists

PPA to be removed: unity-team hud

comm: file 2 is not in sorted order

Package revert list generated:

gir1.2-dbusmenu-glib-0.4/precise gir1.2-dbusmenu-gtk-0.4/precise

indicator-appmenu/precise libdbusmenu-glib4/precise libdbusmenu-gtk3-4/precise

libdbusmenu-gtk4/precise libunity-core-5.0-5/precise unity/precise

unity-common/precise unity-services/precise

Disabling unity-team PPA from

/etc/apt/sources.list.d/unity-team-hud-precise.list

The following packages will be DOWNGRADED:

gir1.2-dbusmenu-glib-0.4 gir1.2-dbusmenu-gtk-0.4 libdbusmenu-glib4

libdbusmenu-gtk3-4 libdbusmenu-gtk4 indicator-appmenu

Note that it found the packages I had installed and offered to downgrade them. Say yes and ppa-purge will put you back to archive state. Neat!

Next-Gen Linux Desktop LXQt Makes First Public Release

The first public release of LXQt, the next generation of popular lightweight Linux desktop environment LXDE, has been made available to download.

628dd__lxqt

Its arrives almost a year after the teams behind the LXDE Qt initiative and Razor-Qt desktop projects decided to merge. By pooling resources to focus on a single desktop environment, instead of two, the team say they “hope offer the best possible experience while reusing as much code as possible.”

Ten months on and number of core improvements have been made, both in the way the desktop works and in the feature set it offers. Today’s beta release, intended for early testers and developers, is already said to be ‘stable and usable’.

The Beginning of Something Beautiful

The unified development team behind the project are continuing to focus on offering a lightweight and user-friendly alternative to the heavier, increasingly complex shells. LXQt will remain well suited to lower speed computers using a leaner, faster and modular code base than that currently offered by the GTK+ based LXDE.

Several significant changes have bridged the previous formal release of RazorQt (0.5.2) and today’s debut, including a Qt port of the PCManFM file manager, improvements to system settings, new modular components, and on-going progress in supporting both Qt5 and the Wayland display protocol.

Development of the GTK+ version of the shell will, the team say, continue for the foreseeable future. Those running Lubuntu 14.04 LTS certainly have no need to panic, with Lubuntu devs committed to providing three years of ongoing fixes.

The team behind the Ubuntu spin have previously stated their intention is to transition to Qt-based desktop as early as Lubuntu 14.10. Whether this happens will be decided in the coming months.

Trying it Out

LXQt is in active development and so it is not recommended for use on any device you hold dear.

The Lubuntu Daily PPA plays host to the required packages for LXQt, including a meta-package to simplify installation.

A number of Qt dependencies will be pulled in as part of the installation process. Those wrestling with a particularly pathetic internet connection should plan accordingly.

Source tarballs, install details for Arch and Debian users, and links to more information can be found on the newly launched website for the project.

You can install it using the following commands:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:lubuntu-dev/lubuntu-daily
sudo add-apt-repository ppa:gilir/q-project
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install lxqt-metapackage

Once installed, log out current session and select log in with LXQt Desktop:
