Following yesterday's news that Ubuntu 12.10 will drop the Unity 2D desktop, I carried out some quick tests comparing the latest state of the Unity desktop with Compiz against the lightweight Unity 2D desktop that's now being removed. To not much surprise, the composited Unity desktop still has some performance shortcomings for OpenGL workloads compared to Unity 2D.

Following the news shared today that Ubuntu's delayed their Wayland System Compositor adoption from Ubuntu 12.10 to at least Ubuntu 13.04 there was the more positive news that there's an updated third-party spin of an Ubuntu derivative running Wayland. This article has some more information on that new "RebeccaBlack OS" release along with screenshots that provide a glimpse of where the Wayland adoption is at today.

Ubuntu 12.10 will not be shipping with a Wayland-based system compositor as was once hoped for, but the experimental system compositor can be enabled from a PPA in a very primitive state.

Aside from VMware virtualization smacking Oracle VirtualBox when it comes to the OpenGL support that's passed through to VM guests, VMware Fusion 4 also does a nice job at outperforming VirtualBox when it comes to computational-focused workloads.

Earlier this year I said VMware's virtual GPU driver was running fast for Linux -- in comparison to Oracle's VM VirtualBox 3D guest acceleration support. This continues to be the case with VMware's OpenGL stack leading the way with superior support and performance. Recently I ran some desktop virtualization tests under VMware Fusion 4.1.3 and Oracle VM VirtualBox 4.1.18 from the Retina MacBook Pro with OS X 10.8 Mountain Lion host. Even with the OS X host, VMware's 3D support exposed to the Ubuntu 12.04 LTS virtualized guest was much faster.

Days ago benchmarks were shared from OpenBenchmarking.org that compared AHCI and IDE modes under Linux when it came to the resulting disk performance. There was a fair amount of interest generated out of that so some AHCI vs. IDE mode comparisons from a Serial ATA 3.0 SSD on an Ubuntu Linux host were benchmarked at Phoronix.
