For those curious about the impact of running Intel "Haswell" HD Graphics 4600 on Ubuntu 14.04 LTS and then pulling in the latest Mesa 10.3-devel code followed by the Linux 3.15 kernel, it's not entirely a happy story if you are looking to maximize your Intel Linux graphics performance capabilities.
Having done a clean install of Ubuntu 14.04 LTS this week on a Core i7 4770K system I figured I would do the usual graphics driver performance update of comparing Ubuntu 14.04 out-of-the-box (Linux 3.13 + Mesa 10.1) against pulling in the latest Oibaf PPA packages to have xf86-video-intel 2.99.911 DDX and the Mesa 10.3-devel Git master code (a big leap from Mesa 10.1.0). Lastly, with the updated Intel user-space graphics drivers I then updated kernel-space by moving to the Linux 3.15 kernel via the Ubuntu Mainline Kernel PPA.
After this week having carried out benchmarks showing Intel's Windows 8.1 OpenGL driver is outperforming their open-source Linux driver but NVIDIA's driver on Ubuntu Linux is commonly faster than Windows 8.1, the time has come to benchmark several different AMD Radeon graphics cards under Ubuntu 14.04 LTS and Windows 8.1 Pro x64 with all available updates and each OS using the latest Catalyst 14.4 driver.
Red Hat was flush with announcements in conjunction with the OpenStack Summit in Atlanta last week, as we covered here. The company announced that itt is open sourcing the ManageIQ cloud orchestration platform, and it also announced some important new collaboration deals surrounding OpenStack. However, one thing that also became clear in Atlanta is that Canonical's new focus on delivering and supporting private OpenStack clouds is going to create very direct competition with Red Hat.
In the past when comparing the Linux and Windows performance with NVIDIA graphics when using their proprietary drivers, the performance has largely been the same. With the very latest drivers on each platform, Ubuntu 14.04 LTS seems to have an advantage over Windows 8.1 in many of the tests. With Ubuntu 14.04 LTS we were using the NVIDIA 337.19 Beta as the latest publicly available driver at the time of testing while for Windows 8.1 Pro x64 the 337.50 driver was their latest equivalent. As usual for ensuring accuracy and being a fair "out of the box" comparison, the stock settings were used for each operating system.
Edubuntu 14.04 LTS Trusty Tahr was released few week ago. It the latest of ubuntu-derived based on ubuntu 14.04 LTS that dedicated for users with a modern and complex computing environment suitable for classroom/educational use.
This release is the second LTS (Long Term Support) version of the Edubuntu, it will be supported for 5 years, until April 2019.
With Qt5 updates coming just every six months and Ubuntu 14.10 coming out in October, it's fairly expected that Qt 5.3 will be part of Ubuntu 14.10 and it's now been mostly confirmed via the ubuntu-devel list. Qt5 is becoming an increasingly important component to the Ubuntu stack due to its use within Unity 8, etc. Qt 5.3 is also a requirement for the upcoming KDE Plasma Next work. Kubuntu developers though don't intend to ship the next-generation KDE stack in Kubuntu 14.10 by default but to just make it available for those wishing to install it after the fact.
A precursory glance at the above screenshot might give the impression that this is yet another Ubuntu Linux review. However, a closer look at the logo in the bottom left corner reveals that nothing could be farther from the truth. Today we’ll be taking a quick look at the Unity desktop environment on Arch Linux.
