Installing Ubuntu 12.04 LTS in Acer Aspire One D255E Netbook

I previously installed Ubuntu 10.04 LTS on my Acer Aspire One D255E network (Atom N455 with GMA3150 GPU), and there were quite a few issues to solve with Ethernet, Wifi and the SD Card but eventually everything worked fine. I have now upgraded it to Ubuntu 12.04 LTS, using the instructions I posted yesterday. The good news is that WiFi and the SD card worked right after the installation, but Ethernet would not work and there were 2 new issues: The system was very slow The touchpad would not work It might be possible that the touchpad and Ethernet issues do not occur by doing a fresh installation with Ubuntu 12.04 ISO, but I haven’t tried. Improving Ubuntu 12.04 Performance I noticed that if you just moved the mouse over the launcher, compiz (composting window manager handling 3D acceleration via OpenGL) would use 100% CPU. I ran glxinfo to verify direct rendering was used. This was the case, so the …

Upgrading Ubuntu 10.04 LTS to Ubuntu 12.04 LTS

If you are using Ubuntu 10.04 LTS and were expecting Ubuntu 12.04 LTS to be available in the Upgrade Manager, you were wrong. Well, at least I was wrong… Canonical won’t make it available via the Upgrade Manager in the first release, but only in July with Ubuntu 12.04.1 release, and the company recommends that most LTS users wait until then before upgrading to 12.04. But if you can’t possibly wait that long, you can run: do-release-upgrade -d or update-manager -d to upgrade from Ubuntu 10.04 (Lucid Lynx) to Ubuntu 12.04 (aka Precise Pangolin). The first command will run in the terminal, the second will start the Update Manager and allow you to select “New Ubuntu release ‘12.04’ is available”. For details on why you should NOT upgrade yet, see http://askubuntu.com/questions/125825/upgrading-lts-to-lts-server-why-wait-for-the-first-point-release. The first time I tried to upgrade I had the following errors: Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade: The package ‘update-manager’ is …

How to Create Your Own Debian / Ubuntu Image for Mele A1000 (AllWinner A10 Based STB)

Developers working on AllWinner A10 have released an Ubuntu 10.04 LTS SD card image (4GB) for the Mele A1000. I’ll show how you can create your own Debian or Ubuntu image based on this image for any size of SD Card using Debian 6.0 (Squeeze) and the recent Ubuntu 12.04 (Precise Pangolin) as example. The current image is not perfect, for example Ethernet doesn’t work (but you can still get network connectivity with WiFi), the NAND flash can not be accessed, the system does not appear to be very stable when running X and a few more issues. But this will be fixed by the developer community over time. First download the SD card image wget http://hands.com/~lkcl/mele-ubuntu-lucid.img.lzma Install 7z (if you don’t have it yet) and decompress the file: sudo apt-get install p7zip-full 7z x mele-ubuntu-lucid.img.lzma The decompressed size is 4008706048, which might be larger than your 4GB SD Card (as it was my case). If you card is larger, …

AppliedMicro Unveils ARMv8 64-bit Apache 2 Implementation for X-Gene SoC

Last year, Applied Micro announced their Gene-X 64-bit ARMv8 core at ARM Techcon 2011, and showed a minimal demo based on Xilinx Virtex-6 FPGA booting Linux ARM 64-bit  to the command line. Since then, the company has made progress and just announced the availability of an Apache 2 web server implementation on their 64-bit ARMv8 X-Gene Server-on-Chip. This is the very first implementation of a  fully-functional server platform running a real-world application on 64-bit ARM-based processor, said Vinay Ravuri, Vice President and General Manager of Processor Products at AppliedMicro. The platform is now capable of running a full LAMP (Linux, Apache, MySQL and PHP) software stack. Back in 2011, the company announced ARMv8 support for Linux  would be developed by Redhat and be available in Fedora. This 64-bit ARM web server implementation enable OEMs, ODMs, Cloud Service Providers, Independent Software Vendors and other development partners to conduct early stage performance benchmarking and software development in parallel with silicon development. The X-Gene platform …

Samsung Officially Unveils the Quad Core Cortex A9 Exynos 4412

Yesterday, Samsung introduced the first quad-core Cortex A9 application processor built on the High-k Metal Gate (HKMG) low-power process technology. the The Exynos 4412, clocked up to 1.4GHz, targets smartphones and tablets and enables double the processing power at a 20 percent lower power bill over the 45nm process-based Exynos 4210 (Dual core Cortex A9). Power efficiency has been improved thanks to hot-plug functionality to support on-off switching for each core and per-core dynamic voltage & frequency scaling (DVFS).  The Exynos 4412 is pin-to-pin compatible with the 32nm process based Exynos 4 Dual (aka Exynos 4212) making it simply a replacement part for existing designs based on Exynos 4212. The new processor also features a video hardware codec engine capable of recording and playing 1080p video @ 30fps (MPEG4 ASP/H.264 HP/H.263 P3 encoding and decoding, and MPEG2/VC1 and WMV9 decoding) , an embedded image signal processor interface for high-quality camera functionality and an HDMI 1.4 interface. Here’s a system diagram …

Linaro 12.04 Release with Kernel 3.4 and Android 4.0.4

Linaro has just released version 12.04 based on Linux Kernel 3.4-rc3 and Android 4.0.4_r1.1. This release already provides Ubuntu 12.04 LTS images for Pandaboard, Snowball, Origen and Versatile Express, and all community builds (nano, ALIP…) are based on Ubuntu Precise Pangolin as well. This should provide significant performance boosted compared to Ubuntu 11.10 thanks to hard-float support and other optimization (See Phoronix Benchmarks). A lot of work since to have gone into big.LITTLE implementation, HTML5 is now supported in Firefox, and it seems Linaro is still working on ARMv6 as they provided VP8 optimizations and improved the toolchain for this architecture. Here are the highlights of the release: Android Finished Snowball Multimedia enablement. Updated all builds to AOSP ICS 4.0.4_r1.1. Switched all builds to 4.7. Updated base toolchain components MPFR and GMP. Ported htop to Android. Ported stressapptest to Android for big.LITTLE Testing. Implemented and ran weekly big.LITTLE tests. Integrated Versatile Express RTSM 3.4 Linux Kernel upgrade. Created a Versatile …
