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 🙂

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:

First Linux Kernel Update Arrives for Ubuntu 14.04 LTS, Upgrade Now

buntubanner

A security problem discovered in the Linux kernel affecting the Ubuntu 14.04 LTS, Ubuntu 13.10, Ubuntu 12.10, Ubuntu 12.04 LTS, and Ubuntu 10.04 LTS operating systems has been fixed by Canonical.

Every now and then, Canonical issues Linux kernel updates for all the operating systems that are being supported at that time. In this case, there are five distributions that have received this new upgrade, but it’s interesting to note that not all the OSes share the same kernel, which means that it was a problem common to all, regardless of the version.

“A flaw was discovered in the Linux kernel’s pseudo tty (pty) device. An unprivileged user could exploit this flaw to cause a denial of service (system crash) or potentially gain administrator privileges,” reads the official security notification.

The security flaw can be fixed if you upgrade your system(s) to the linux-image-3.13.0-24-generic, (3.13.0-24.47), but this is only true for Ubuntu 14.04 LTS (Trusty Tahr). Other operating systems feature different Linux kernels and the versions will be different.

Upgrading the Linux kernel is not something to be taken lightly. Most of the time, some important fixes are implemented with new versions of the kernel and users should upgrade as soon as possible. Ubuntu operating systems will usually notify users about any updates that need to be applied.

There is one caveat though. It’s possible to have some problems after the restart if you previously installed the video drivers manually. For example, the NVIDIA proprietary driver registers the specific modules during the installation, but you may need to re-register those modules again if the system is not booting anymore.

This is just the first Linux kernel update for Ubuntu 14.04 LTS (Trusty Tahr) and it arrives only three weeks after the official launch. Canonical has pledged to support the operating system until 2019, which means that, if you stick with this distribution, you might be the beneficiary of countless similar updates.

Don’t forget to reboot your computer after the upgrade, and be careful. Make sure you save any work you’re doing before hitting that button.

ATTENTION: Due to an unavoidable ABI change, the kernel packages have a new version number, which will force you to reinstall and recompile all third-party kernel modules you might have installed. Moreover, if you use the linux-restricted-modules package, you have to update it as well to get modules that work with the new Linux kernel version.

Upgrade to GNOME 3.12 in Ubuntu 14.04

gnom312

If you’ve recently installed or upgraded to Ubuntu GNOME 14.04 LTS then you will no doubt be enjoying a stable, dependable GNOME Shell experience.

But I suspect that the more nerdcore users among you would rather trade in the stability that’s offered up by default for a newer, badder, and potentially much buggier experience. You want to know how to upgrade to GNOME 3.12 in Ubuntu 14.04?

Well, I’m here to show you how. First though, I need to get all parental with you.

GNOME 3.10 is default for a reason

GNOME 3.12 was released in late March to much fanfare and some fantastic reviews. But despite going ‘stable’ before Ubuntu 14.04 LTS, released last month, it is not available to install from the Ubuntu 14.04 repositories — why?

Simply put it came too late in the development cycle to give enough time to thoroughly vet, test and ensure it was up to the standards an LTS release commands, and its users expect. Defaulting to the older 3.10 release makes sense as it benefits from having an extra cycle of thorough testing under its belt.

It’s for this reason that upgrading to GNOME 3.12 is not recommended.

Understood? Great, let’s move on to the fun stuff.

How to Upgrade to GNOME 3.12 in Ubuntu 14.04

To follow this guide correctly you need to be running the latest release of Ubuntu (14.04 LTS) or Ubuntu GNOME. If not, stop now; you must upgrade before you continue. If you don’t you can expect a whole world of hassle to follow.

If you’re running the regular version of Ubuntu (i.e., the one with Unity) then you should go ahead and grab GNOME 3.10 from the Ubuntu Software Centre before proceeding.

Add the GNOME 3.12 PPA

It was originally expected that GNOME 3.12 would be made available through the standard GNOME Team PPA following the release of Trusty. Three weeks hence, that hasn’t happened. As of writing it contains a handful of minor 3.10 packages and not anything related to the newest release.

However, the GNOME Team Staging PPA does contain all of the various 3.12 packages one needs to upgrade. Adding this archive should, the developers behind it say, result in a desktop that ‘runs smoothly’ but that packages included within have not been deemed ‘ready for general use’.

Providing you’re a dab hand with the PPA Purge tool you should be okay to continue. First, let’s check for and install any outstanding distribution updates:

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

Install any packages waiting by hitting the enter key.

Once complete, or if you have no pending updates at all, you can add the GNOME 3 Team Staging PPA. To do this, open a new Terminal window and enter the following commands:

sudo add-apt-repository ppa:gnome3-team/gnome3-staging
sudo apt-get update && sudo apt-get dist-upgrade

You’ll be prompted to enter your password before the upgrade process can begin. Pay attention to any notices or alerts given. If all is acceptable agree to the installation by hitting the ‘y’ key.

Extras

For a true GNOME experience you may wish to grab some of the new GNOME applications, such as the Polari IRC client, GNOME Maps and the GNOME Web browser. To install these three in particular run the following command:

sudo apt-get install epiphany-browser gnome-maps polari -y

 

After everything has finished doing what it needs to, you’re safe to reboot!

After Care

Logging In

If you’re coming from Unity, Xfce or another desktop environment don’t forget to select the GNOME session from the login screen before logging in.

Drawbacks

New Apps

GNOME Weather & GNOME Maps in 3.12

For me, in my lone experience, GNOME 3.12 on Ubuntu 14.04 runs pretty much fine. There do not appear to be any significant performance regressions after upgrading, though I do see the odd, infrequent visual glitch that occurs when opening the activities overlay, and the occasional disappearing drop shadow from under an app. But as bugs go these are hardly deal breakers.

Performance seems to be on par with GNOME 3.10; applications open with just as much pep and there are no noticeable drops in interactivity.

I was marginally disappointed to find that the all new GNOME Videos application has not been packaged up in this PPA. One suspects there are reasons for this (likely requiring a newer version of gstreamer).

With the lack of testing this has received, bugs are pretty much guaranteed. If you want stability stick with the thoroughly tested GNOME 3.10.

Downgrade from GNOME 3.12 to 3.10

But if you want shiny new features and access to the latest builds of GNOME apps then don’t be afraid to give the staging PPA a whirl. You can always ‘downgrade’ using PPA Purge if things go awry.

sudo apt-get install ppa-purge
sudo ppa-purge ppa:gnome3-team/gnome3-staging

Ubuntu 14.10 Utopic Unicorn Daily CD Images Released for Testing

The Unicorn is Here

The Unicorn is Here

It’s not even two weeks since the latest LTS version of Ubuntu was released, and here we are, a new testable beta of the next Ubuntu is available for download:

“The first autosync with Debian is running right now, so don’t get overexcited and sync something by hand that the automated machinery will get to in the next hour. The buildds will be very, very angry with us for a couple of days due to the above autosync. Have some patience. Upload your merges, and don’t babysit the queues. You’ll thank me for it. You might even want to go out for a walk, get some fresh air, feed a duck, that sort of thing,” said Adam Conrad on the official mailing list.

The developer explained that ruby-defaults has been updated to version 2.1, boost-defaults has been updated to version .55, a new binutils snapshot has been added, and all the other packages have received some “tiny unicorns” (it’s probably a given that many of the Ubuntu developer’s statements will be littered with various puns).

Ubuntu 14.10 (Utopic Unicorn) is also the perfect version for the developers who want to push some of the updates that didn’t make it into Ubuntu 14.04 LTS (Trusty Tahr) or that got rejected for whatever reason. This is the perfect playground for new packages, and users might see some very interesting things in the final released of Ubuntu 14.10.

“I know post-LTS releases are always an exciting barrage of tossing in all the things you didn’t think you could land in an LTS without the release team glaring at you, and I’m sure this one will be no exception. So, have fun, happy uploading, and do try to fix two bugs for every one you upload,” also said Adam Conrad.”

It’s probably not a good idea for the average user to go out there and grab a copy, beta + bugs, so it’s never advised to use any beta operating system on your main every day machine.

But, if you’re like me, a sucker for new stuff with no patience whatsoever, then you can grab the images here:

http://cdimage.ubuntu.com/daily-live/current/

Create a LiveUSB as normal and give it a whirl before installing, and if you intend to install, I strongly advise you to back up all your data and settings first, just in case.

As you may have guessed, I’ve dived in the deep end and installed it as my main os on my only machine, so watch this space for updates on features as they come, and the occasional panicky post where things have totally wrong.
