Xubuntu 14.04 LTS Trusty Tahr is an official derivative of Ubuntu 14.04 LTS, released with many improvement and updates. Come with LTS (Long Term Support) version Xubuntu 14.04 will be supported by xubuntu team and developer for 3 years. Without adding tons of new features, Xubuntu focuses on stability, simple, light and fully customizable.
Xubuntu 14.04 LTS Trusty Tahr uses the Xfce desktop environment instead of Unity 7, so it works very well as a lightweight alternative to regular ubuntu desktop. On this release Xubuntu developers have introduced the new Whiskermenu a more modern menu with the ability to easily launch your favorite applications, as well as have a useful search bar and various customizations. You can also find the new Xfwm4 4.11 which includes support for Sync VBlank, Xfdesktop 4.11 and other updates.
That means that if you use Ubuntu 12.10, you should upgrade to Ubuntu 13.10 (Ubuntu 13.04 has already reached end of life) and then (recommended) to 14.04. That's because after May 16 2014, "Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 12.10".
It's also important to mention that PPA maintainers will no longer be able to upload packages for Ubuntu 12.10 after that date.
Everyone knows that Ubuntu is not one of the most customizable operating systems, which is one of the problems that often come up in the Linux community. This is where the Ubuntu Tweak software will really help its users make head or tails of the Ubuntu Linux distro in a way that very few applications can.
The idea was audacious: Combine Android, the most popular mobile version of Linux, with Ubuntu, the leading Linux desktop operating system, on a single smartphone that swapped between the two depending on whether the device was docked. Alas, Ubuntu for Android seems to have moved off the active roster as Canonical focuses on its own Ubuntu Touch project, and a new exchange on a Ubuntu project-tracking website seems to suggest Ubuntu for Android may be dead. (See update below.)
Linus Torvalds is back in the news, but this time it's good. Torvalds tops the news tonight for being the recipient of a prestigious award. LibreOffice 4.1.6 was released today with about 90 fixes and squeezably fresh Tails 1.0 is making headlines. And our final story tonight, The Register is reporting that upgrading Ubuntu 13.10 to 14.04 "may knacker your Linux PC."
Ubuntu for Android sounds like a great idea. According to the official website, Ubuntu for Android provides a full desktop experience, including office software, web browsing, email and media applications, on Android phones docked to a screen and keyboard.
Canonical didn't put too much effort in this project after it was officially announced and besides a vague late 2012 launch date, there is not much information about it. Users don't even have access to a Beta and they can't really test it.
The Ubuntu developers have already started working on the next Ubuntu version, and the first development images have been produced. Don't expect too much from the new Ubuntu build, at least not yet. It will be a couple of months until some major changes are visible.
If you boot it right now it still says Ubuntu 14.04, so you can see that this is only a placeholder for the features that will get implemented along the way.
With Ubuntu 14.04 LTS there is improved support for multi-GPU laptops (commonly what's branded as NVIDIA Optimus configurations) where there is a discrete NVIDIA GPU used for high performance workloads to complement the low-power Intel integrated graphics. Ubuntu 14.04 LTS features better support for these Optimus / DRI PRIME configurations on both the open and closed-source graphics drivers. Here's the Ubuntu 14.04 multi-GPU experience along with some OpenGL benchmarks and power consumption numbers between the different configurations.
Now that Ubuntu 14.04 LTS is out the door, I tested it out on a ASUS Zenbook Prime ultrabook with an Ivy Bridge class Intel Core i7 3517U CPU that has HD Graphics 4000 plus a discrete NVIDIA GeForce GT 620M 1GB GPU.
