Original OSNews Interviews Today we are very happy to publish a very interesting Q&A with major freedesktop.org members: the founder Havoc Pennington (also of Debian, Gnome and Red Hat fame), Waldo Bastian (of SuSE & KDE fame), Keith Packard and Jim Gettys (of X/XFree86/fontconfig/w3c fame) and David Zeuthen, a new member who's taking over the ambitious HAL project. In the article, we discuss about general freedesktop.org goals, status and issues, the role of KDE/Qt in the road to interoperability with Gnome/GTK+, HAL (with new screenshots), the new X Server aiming to replace XFree86 and we even have an exclusive preliminary screenshot of a version of Mac OS X's Exposé window management feature for this new X Server! This is one article not to be missed if you are into Unix/Linux desktop!

SGI systems have virtualized their GPUs for awhile now. Basically, a virtual GPU means that the real graphics hardware is fully abstracted from the application, and the OS has full control over managing the HW. Just as Windows and Linux have virtual memory and a virtual CPU (preemptive multitasking), IRIX machines have a virtual GPU. You can throw more graphics pipes into the virtual GPU pool, and automatically get increased performance. Also, the abstract nature of the interface makes it easy to share the GPU among many concurrently rendering applications, just as preemptive multitasking makes it easy to share the CPU among concurrent applications.
