X Window System

Filed under
Linux

The X Window System (www.x.org) was created in 1984 at the Massachusetts Institute of Technology (MIT) by researchers working on a distributed computing project and a campuswide distributed environment, called Project Athena. This system was not the first windowing software to run on a UNIX system, but it was the first to become widely available and accepted. In 1985, MIT released X (version 9) to the public, for use without a license. Three years later, a group of vendors formed the X Consortium to support the continued development of X, under the leadership of MIT. By 1998, the X Consortium had become part of the Open Group. In 2001, the Open Group released X version 11, release 6.6 (X11R6.6).

Linux Performance Hunting Tips - Take Copious Notes (Save Everything)

Filed under
Linux

Probably the most important thing that you can do when investigating a performance problem is to record every output that you see, every command that you execute, and every piece of information that you research. A well-organized set of notes allows you to test a theory about the cause of a performance problem by simply looking at your notes rather than rerunning tests. This saves a huge amount of time. Write it down to create a permanent record.

Graphics: XWayland and Mesa

  • XWayland Gets Patches For Better EGLStreams Handling
    While the recently released X.Org Server 1.20 has initial support for XWayland with EGLStreams so X11 applications/games on Wayland can still benefit from hardware acceleration, in its current state it doesn't integrate too well with Wayland desktop compositors wishing to support it. That's changing with a new patch series.
  • Intel Mesa Driver Finally Supports Threaded OpenGL
    Based off the Gallium3D "mesa_glthread" work for threaded OpenGL that can provide a measurable win in some scenarios, the Intel i965 Mesa driver has implemented this support now too. Following the work squared away last year led in the RadeonSI driver, the Intel i965 OpenGL driver supports threaded OpenGL when the mesa_glthread=true environment variable is set.
  • Geometry & Tessellation Shaders For Mesa's OpenGL Compatibility Context
    With the recent Mesa 18.1 release there is OpenGL 3.1 support with the ARB_compatibility context for the key Gallium3D drivers, but Marek Olšák at AMD continues working on extending that functionality under the OpenGL compatibility context mode.
  • Mesa Begins Its Transition To Gitlab
    Following the news from earlier this month that FreeDesktop.org would move its infrastructure to Gitlab, the Mesa3D project has begun the process of adopting this Git-centered software.
