Why Is Moblin's X.Org Stack Faster Than In Ubuntu?

Filed under
Software

Canonical's Scott James Remnant recently set out to explore why X.Org started up so much faster on Moblin than on Ubuntu (particularly, the latest 9.04 development code). On an Atom-based netbook (the Dell Mini 9) he found it took Ubuntu's X Server about four seconds to start before the session manager was called. With Moblin on the same hardware it took just about a second and a half.

Scott began analyzing the X Server patch-set for Moblin, that included enabling UXA acceleration by default, avoiding duplicated saved hardware states, reducing the driver boot-time, and disabling other operations. However, Ubuntu already incorporated all of these patches besides using UXA acceleration. Ubuntu's X Server also has a few extra patches, but those didn't seem to impact the performance.

Red Hat Summit

  • Red Hat Summit Advocates the Power of Participation
    Red Hat hosted its annual Red Hat Summit customer event June 28-30 at the Moscone Center in San Francisco, with a theme of harnessing the power of participation. Once again, the DevNation developer event, which is the successor to JBoss World, was co-located with Red Hat Summit. For JBoss, 2016 is a particularly significant year as it marks 10 years since Red Hat acquired it. At DevNation, Red Hat announced the new JBoss Enterprise Application Platform (EAP) 7 release, providing new cloud-enhanced capabilities for Red Hat's flagship middleware platform. JBoss is now also working to help enable Java for the container era, with the launch of the MicroProfile Project, an effort to optimize enterprise Java for a microservices architecture. Java wasn't the only focus of DevNation this year either, as Microsoft took center stage too, announcing the availability of its .NET Core for Red Hat Enterprise Linux. In this slide show, eWEEK takes a look at some of the highlights of the Red Hat Summit and DevNation 2016 events.
  • How Red Hat is tailoring OpenStack to fit … everyone
    Even though there have been no major changes announced to the OpenStack platform of late, it was still one of the most talked about subjects at this year’s Red Hat Summit. Red Hat plays a significant role in the development of the platform and is very proud of its contribution to the community.
  • New technologies foster an open-source environment
    In 2007, when 3scale, Inc. was founded, some people thought it was crazy to be investing so much time and energy into API. But Steven Willmott, CEO of 3scale, Inc., said that even at that time his team knew that the future was API-driven, and they wanted to help that happen.
