LibreOffice 4.4.5, the final stable release before LibreOffice 5.0 stable which is scheduled to be released next week, has been announced today.

It is the fifth bugfix release from the 4.4 branch of LibreOffice which contains new features and program enhancements. As such, the version is stable and is suitable for all users. This version may contain a few annoying bugs which will be fixed in the next bugfix versions to come.

How to Upgrade to LibreOffice 4.4.5:

For Ubuntu 15.10, Ubuntu 15.04, Ubuntu 14.04, Ubuntu 12.04 and derivatives (e.g., Linux Mint 17.x, and Elementary OS Freya), follow below steps to upgrade the office suite from PPA.

1. To add LibreOffice PPA, open terminal either from the Dash/Launcher or via Ctrl+Alt+T shortcut keys. When it opens, run below command:

sudo add-apt-repository -y ppa:libreoffice/ppa

libreoffice-ppa

2 After added the PPA, open Software Updater and you’ll see the new LibreOffice release available for upgrade after checking for updates.

Just click Install Now button to install/upgrade it.

You can also use Synaptic Package Manager to upgrade the office suite.

3. Optional For those who want to revert back to the original LibreOffice version in Ubuntu, run below commands to install ppa-purge and purge the PPA which also downgrades all installed packages from that PPA:

sudo apt-get install ppa-purge

sudo ppa-purge ppa:libreoffice/ppa

Nvidia announced the 352.30 release of its Linux driver yesterday with GeForce 910M support and various important fixes.

Release highlights of Nvidia 352.30:

  • Fixed a bug that caused poor video post-processing performance in VDPAU when operating on a large number of video streams simultaneously.
  • Fixed a bug that could cause an Xid error when terminating a video playback application using the overlay presentation queue in VDPAU.
  • Updated nvidia-installer to avoid recursing too deeply into kernel source trees under /usr/lib/modules, mirroring an existing restriction on recursion under /lib/modules.
  • Fixed a rare deadlock condition when running applications that use OpenGL in multiple threads on a Quadro GPU.
  • Fixed a kernel memory leak that occurred when looping hardware – accelerated video decoding with VDPAU on Maxwell-based GPUs.
  • Fixed a bug that caused the X server to crash if a RandR 1.4 output provided by a Sink Output provider was selected as the primary output on X.Org xserver 1.17 and higher.
  • Fixed a bug that caused waiting on X Sync Fence objects in OpenGL to hang indefinitely in some cases.
  • Fixed a bug that prevented OpenGL from properly recovering from hardware errors or sync object waits that had timed out.

Install Nvidia 352.30 from PPA:

For Ubuntu 15.10, Ubuntu 15.04, Ubuntu 14.04 and derivatives (e.g., Linux Mint 17.x, and Elementary OS Freya), the new driver can be easily installed from an PPA repository:

Relay IRC Client

Relay is a new IRC client designed for Elementary OS that aims to be small, fast, and elegant. It’s written in Vala and also works in Ubuntu and other Linux.

Relay uses very few libraries and takes less memory (<30mb usually). The project was created in June of 2015 so as of now it is a young project with functionality rapidly being added to it. So far, it features:

  • drag and drop to Hastebin – drag files to the paste icon will upload all of them and put the URL’s in the output window.
  • A missed message count.
  • Highlighting tabs with activity from IRC servers.
  • Drag and drop reordering of tabs.
  • Automatic IRC channel connecting
  • URL parsing and the ability to open your browser when clicked
  • Highlights the name of your or anyone else when mentioned in a chat
  • Right click tab switching.
  • The ability to switch channels through tabs or the sidebar.
  • It supports languages that use UTF-8 characters.
  • Although Relay was built on Elementary OS it will switch the theme depending on what operating system you are using.
  • The ability to search users
  • The ability to see where you left off since you last visited a tab
  • The ability to control many settings and set colors in the UI
  • Click a user name to have their name placed in the text entry
  • Private messaging and ability to block users
  • The ability to turn on or off joining or exiting messages
  • Creates a datestamp every 5 minutes to give you a timeline of what has happened

At the moment of writing this tutorial there are two bugs for Ubuntu user and I’ve reported them to the project page:

  1. In Unity desktop, when you try to minimize Relay window by clicking its icon on left Launcher, session crashes immediately and brings you back to login screen.
  2. In Gnome Shell, there’s a reading issue (Picture 4).

Install Relay IRC client from PPA:

The developer has created a PPA repository for the project. So far, Ubuntu 15.10, Ubuntu 15.04, Elementary OS Freya are supported.

NOTE: Ubuntu 14.04 needs updated version of libgranite (>= 0.3.0) and GTK+3.0 (>= 3.14). You can get them from Gnome Testing PPA and Elementary Stable PPA. But using the PPAs could break your system or make it unstable! Do it at your own risk!

1. To add the PPA, open terminal from the Dash, Launcher, or via Ctrl+Alt+T shortcut keys. When it opens, run command:

sudo add-apt-repository ppa:agronick/relay

relay-irc-client-ppa

2. After added the PPA, install the software via Synaptic Package Manager. Or just run below commands one by one in terminal:

sudo apt-get update

sudo apt-get install relay

For those who don’t want to add PPA, grab the .deb package from the launchpad page.

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:

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
