The Linux graphics stack from X to Wayland

Filed under
Software

In the early 1980s, MIT computer scientist Bob Scheifler set about laying down the principles for a new windowing system. He had decided to call it X, because it was an improvement on the W graphical system, which naturally resided on the V operating system. Little did Bob know at the time, but the X Window System that he and fellow researches would eventually create would go on to cause a revolution. It became the standard graphical interface of virtually all UNIX based operating systems, because it provided features and concepts far superior to its competition. It took only a few short years for the UNIX community to embrace the X windowing system en masse.

In this article, we'll take a look at the development of the Linux graphics stack, from the initial X client/server system to the modern Wayland effort.

What made X so special, of course, is legendary. X was the first graphical interface to embrace a networked, distributed solution. An X Server running on one of the time sharing machines was capable of generating the display for windows that belong to any number of local clients. X defined a network display protocol so that windows from one machine could be displayed on another, remote machine.

  • System76 wants to build its own hardware for its Linux-based computers
    System76 is building up quite a name for itself, being one of a very limited number of companies selling only computers running Linux-based operating systems. Now the aim is to branch out; System76 wants to design and build its own hardware, while representing the open source community as it does so. At the moment, the hardware used in System76 systems is outsourced, but in the future this will change. The company says that it is moving into phase three of its development cycle, and this "moves product design and manufacturing in house." And you should set your expectations high: "We're about to build the Model S of computers. Something so brilliant and beautiful that reviewers will have to add an 11 to their scores."
  • AppCenter Spotlight: Beta Testers
    Over the past month we’ve been beta testing the new AppCenter with a number of developers, from elementary OS contributors to backers of our Indiegogo campaign. After testing out the submission process and getting some apps into the store (and seeing rapid updates!), I wanted to take a moment to highlight some of the first apps.
  • elementary OS to get improved AppCenter, showing off a few new applications
    I have to hand it to the elementary OS guys, they have a massive focus on design and it does look quite incredible. It is easily one of the best looking Linux distributions, which I do admire. Their new AppCenter, for example, looks extremely clean and clear.

Beijing Zoo is No Place for Pandas

I am a Panda lover. I work as a support engineer in an I.T company here in the United Kingdom. Most of my spare time is spent watching different Panda videos -- both old and new videos. Basically, it is my therapy; a 'stress release' for me. I find them to be adorable and precious creatures. As a matter of fact, I would like to volunteer to come to Sichuan. I want to experience and feel what it's like to be a Panda keeper, to be able to interact with them for real. The Panda is China's National Treasure, so it's a shame to watch the Panda videos from Beijing zoo, as the place is disgusting and not ideal for Pandas to live in (and for sure for all the rest of the animals who unfortunately got stuck in this prison cell).

The place looks like a ghost town. Lifeless and languished. Knowing that Pandas wear a thick fur on their body, can you imagine what it feels for them in 30C or 35C (summer temperature)? What it probably feels like all the time? Come on, if you really care, you must do something now, otherwise these Pandas will die. Please bring them back to their sanctuary where they really belong.

Linux 4.11 File-System Tests: EXT4, F2FS, XFS & Btrfs

With the Linux 4.11 kernel potentially being released as soon as today, here are some fresh benchmarks of Btrfs / EXT4 / F2FS / XFS on a solid-state drive and comparing the performance of 4.11 Git back to Linux 4.9 and 4.10. For those wondering if the block/file-system changes of Linux 4.11 have any impact on EXT4/F2FS/XFS/Btrfs for common I/O workloads or how these file-systems are comparing on this latest kernel, here are some benchmarks.
