Debian 10 “Buster” Released

If you’re a recent owner of a Raspberry Pi 4 SBC, you should have had an early taste of Debian 10 “Buster”, but the Raspberry Pi Foundation decided to release their Raspbian “Buster” image before the actual release to lower software development costs, as Debian developers only just announced the release of Debian 10 “Buster”. The new version of Debian supports various desktop environment including Cinnamon 3.8, GNOME 3.30, KDE Plasma 5.14, LXDE .99.2, LXQt 0.14, MATE 1.20, and Xfce 4.12. Beside the official announcement Debian also posted tidbits on their twitter feed, where we learn for example that “Debian 10 buster has 28,939 source packages with 11,610,055 source files”. Officially supported architectures for Debian 10 include i386 and amd64 for x86 targets, arm64, armel and armhf Arm architectures, as well as various other architectures includings MIPS (mips64el, mipsel…), PowerPC (ppc64el), and IBM System z (s390x). One notable change is that GNOME defaults to using the Wayland display server instead […]

SPURV Runs Android Apps in Linux over Wayland

SPURV Architecture

We’ve previously seen it was possible to run Android apps natively inside Linux thanks to Anbox that leverages the Linux kernel in Ubuntu for better integration and performance, and uses an LXC container to run Android operating system. Collabora now offers a different solution with SPURV that runs the full Android OS, including a separate Linux kernel, in its own container and works over Wayland thanks to a graphics bridge from Android to Wayland. Four main components are part of the implementation: Android target device – This component integrates SPURV into Android by using the device infrastructure that the Android codebase provides, and the company specifically the target runs inside of a systemd-nspawn container. SPURV Audio – Bridges the Android Audio Hardware Abtraction Layer (HAL) to the host PulseAudio stack. SPURV HWComposer – Integrates Android windows into Wayland by implementing a HWC-to-Wayland bridge, where HWC is the Android API for implementing display & buffer management. The composer also manages user […]

ODROID-N2 GPU Drivers, Linux 5.0, and Impressive glmarks-es2 Score

Ubuntu 18.04 Gnome Wayland ODROID-N2

ODROID-N2 was announced last February for $63 (2GB RAM), and $79 (4GB RAM), but Hardkernel was not quite ready to take orders at the time. One of the good news is that the 4GB RAM is now available for pre-order with shipping scheduled to start on April 3. Another good news is on the software side with Hardkernel having released the userland Mali-G52 Wayland driver. It does not work well with Linux 4.9 due to incomplete DRM implementation, but it goes work with Linux 5.0 plus some modifications as further discussed in the aforelinked forum thread. The screenshot above, courtesy of odroid forum member memeka , shows ODROID-N2 running Ubuntu 18.04 + Gnome3 + Linux 5.0 on top of Wayland with GPU drivers providing acceleration as shown by glmark2-es2-wayland test program. The benchmark results are pretty impressive:

I’ve never seen such as high score (1,119 points) on Arm hardware. But at the same time, I’ve never run the wayland […]

Self-hosted GLES on ChromeOS, part two

This is a follow-up post from an earlier guest post by Blu about OpenGL ES development on Chrome OS. One can’t practice real-time rendering to disk files for long ‒ it’s just unnatural. So after checking that my habitual GLES tests work as intended on ChromeOS when rendering to an off-screen-buffer-subsequently-saved-to-a-PNG, the next step was to figure out a way how to show frames on screen at a palpable framerate, if possible. Being as new to Chrome OS as the next guy, I had to start from scratch with ‘How to show EGL surfaces on screen fast’. In the comments section to the first article William Barath kindly mentioned that there was a wayland client library on Chromebrew, so I decided to pursue that as I had had (positive) prior experience with wayland. Long story short, the established way on most platforms for connecting wayland to EGL (or vice versa) is to ask wayland/weston for an EGL-compatible window surface, and […]

Maynard is a Wayland based Lightweight Desktop Environment Designed for the Raspberry Pi and Lower-end Hardware

With 3 millions board already sold, the Raspberry Pi board is clearly the most popular ARM Linux development board, and must be one of the most successful Linux device that’s designed to run a Desktop environment. However, the Broadcom BCM2835 processor and lowly 512MB makes it hard to run fully fledge desktop environment such as KDE and Gnome, so most people run LXDE via Raspbian operating systems, and it is much more manageable. However LXDE does not support Wayland, which is supposed to replace the X windows system, and it may not look as nice as it could. So the Raspberry Pi foundation and Collaborra have worked together on a new desktop environment called Maynard that leverages Wayland, and is supposed to be “functional, light and pretty”. This Wayland implementation is based on Weston + GTK, and is using the hardware video scaler (HVS) found in Broadcom BCM2835 to make everything nice and smooth. Although this is still work in […]
