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 […]

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 […]

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 […]

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 […]

Ubuntu Tweak 0.7.0 for Ubuntu 12.04 Precise Pangolin

Ubuntu 12.04 – codenamed Precise Pangolin – will be officially released later today, you may even already run the latest Ubuntu 12.04 beta 2. One day before the official Ubuntu 12.04 release, Ubuntu Tweak 0.7.0 (aka Precise Tweak) has been made available for those that want to customize and customize their system with options not available by defaults. This tool can also be used with older versions as well, but it has some Ubuntu 12.04 specific settings, e.g. turn HUD on/off, tweak login settings for Ubuntu 12.04 and more. This new version of Ubuntu Tweak can change parameters specific to Ubuntu 12.04. For example, you can disable HUD (Head-Up Display) interface or turn on/off shortcuts hits overlay. You can also customize the launcher. You can also change login settings and personalize LightDM. There is also a QuickLists Editor. Additionally, Ubuntu Tweak features an Application Center to find and install popular […]

Ubuntu on AllWinner A10 based Mele A1000 Set-top Box

I’ve recently received and reviewed the 70 USD Mele A1000 STB powered by AllWinner A10, but haven’t been able to hack it yet since I’ve have not received the USB to Serial cable necessary for debugging the board. However, somebody else (Tom Cubie) had time to hack the box and run Ubuntu from a SD card (while still keeping Android in the flash) as you can see below. This port does not seem to include hardware accelerated GUI just yet, but this is definitely a step in the right direction. Tom said he just followed the instructions at http://rhombus-tech.net/allwinner_a10/hacking_the_mele_a1000/ and http://rhombus-tech.net/a10_mmc_boot/ to have Ubuntu working, but those do not appear to be that clear at the moment.

Cross-compiling the ARM Linux Kernel in Ubuntu 12.04 LTS

Yesterday I installed Ubuntu 12.04 ‘Precise’ Beta 1 in Virtual Box to give it a try (I could not manage to have HUD working btw), and today, I’ve noticed an article entitled “Ubuntu 12.04 ‘precise’ and cross compilation of ARM kernels” explaining how to build Linaro ARM kernel in Ubuntu 12.04. So I’ve decided to give it a try, especially it seems straightforward. I followed the instructions in the aforementioned link,  it basically worked except I had to install dpkg-dev package that also installed the build essentials (gcc, g++, etc…) and use sudo for some commands. You’ll notice the name change for the ARM gcc toolchain as it now uses hard-float by default which seems to provide quite a boost in performance for the Pandaboard. Here are the steps I followed: Install the ARM GCC cross compiler and the development package of dpkg:

Retrieve the kernel source:
