Dual Monitor Setup with ATI Graphics Cards in Ubuntu

I’ve recently bought an ATI Radeon HD5450 in order to be able to use multiple displays in Windows XP and Ubuntu 11.04. I’ll explain how to install and configure the ATI drivers in order to use multiple displays and extend the desktop on two monitors. The first thing to do is to install the proprietary ATI drivers and Catalyst Control Center. Click on the icon at the top right of the screen and select “System Settings” in the drop down menu. Then click on “Additional Drivers”, Ubuntu should detect your ATI graphics card automatically and show the following: Click on “Activate” to download and install ATI/AMD proprietary FGLRX graphics driver and Catalyst Control Center (CCC). Alternatively, you could also download the latest linux ATI driver (version 11.12) on ATI website and run ./ati-driver-installer-11-12-x86.x86_64.run After installation, you may have to restart you computer. Once the drivers are installed, if you use […]

Nvidia Announces CARMA Tegra 3 CUDA Development Kit

Nvidia has just unveiled its Tegra 3 development kit, the Nvidia CARMA. The development kit codename has been crowdsourced as Nvidia asked its followers to propose a name and vote for the best name. This development kit particularly targets CUDA, Nvidia parallel computing platform and programming model that enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU). The CARMA hardware has been designed by Seco and features an NVIDIA Tegra 3 ARM Cortex A9 Quad-Core CPU and NVIDIA CUDA GPU QuatroTM. Here are the technical specs for the development kit: CPU NVIDIA Tegra 3 Quad-Core ARM A9 GPU NVIDIA QuadroTM 1000M with 96 CUDA Cores Memory • CPU Memory: 2 GB • GPU Memory: 2 GB Peak Performance 270 Single Precision GFlops CPU – GPU Interface PCIe x4 Gen1 link Network 1x Gigabit Ethernet Storage 1x SATA Connector USB 3x USB 2.0 Display […]

Copy/Paste Text between Windows XP Host and Ubuntu Guest in VirtualBox

I’ve recently upgraded the amount of memory and graphics card in my computer to order to be able to smoothly run virtual machines and support 2 monitors. So instead of using dual boot for Windows XP and Ubuntu, I’m now running Ubuntu in VirtualBox. One thing, I wanted to do is to copy text from the right screen (e.g. Instructions in Web Browser in Windows XP) to the left screen where I have Ubuntu 11.10 running in VirtualBox. This does not work right out of the (virtual)box however. The procedure to enable “Shared Clipboard” is straightforward. First, you need to install the guest additions. While Ubuntu is running, click on “Devices->Install Guest Additions” in VirtualBox top menu, this will start the installation in Ubuntu, simply enter you root password until the installation completes. Restart Ubuntu and you should now be able to copy/paste text between the host and guest machines. […]

15 USD ARM Cortex A8 Linux Computer by Rhombus Tech

Many of you already probably know the Raspberry Pi Foundation 25 USD ARM Linux Computer. Rhombus Tech, another non-profit organization, is planning to design a 15 USD ARM Linux computer (excluding casing, power supply, shipping, VAT and custom duties) that the company claims would be at least 3 times faster that the Raspberry Pi. This computer would be an EOMA-PCMCIA CPU card powered by an Allwinner A10 ARM Cortex A8 CPU clocked at 1.5ghz. Here are the (expected) specifications of this board: Approximately Credit-card size format (56mm x 90mm) An Allwinner A10, 1.5ghz ARM Cortex A8 1GB of RAM At least 1gb of NAND Flash (possibly up to 16gb) Operation as a stand-alone computer (USB-OTG powered) 2160p (double 1080p) Video playback MALI 400MP 3D Graphics, OpenGL ES 2.0 compliant. HDMI, Micro-SD, Headphones Socket, EOMA-PCMCIA-compliant interfaces (RGB/TTL, I2C, USB2, SATA-II, 10/100 Eth) Expansion Header (similar to Beagleboard, IMX53QSB, Origen etc.) With this […]

Build the bootloaders (U-boot & X-Loader) for Pandaboard

I’ve tried to compile u-boot and x-loader for Pandaboard by following the instructions given at http://omappedia.org/wiki/Get_started_with_ubuntu_on_omap4#Bootloaders. I did this in Ubuntu 10.04 LTS with Linaro gcc compiler. Here are the instructions for the build: Create the folders:

mkdir bootloader
cd bootloader

1 2	mkdir bootloader cd bootloader

Get u-boot and checkout the omap4_dev branch:

git clone git://git.omapzoom.org/repo/u-boot.git
cd u-boot
git checkout L24.9

git clone git://git.omapzoom.org/repo/u-boot.git

cd u-boot

git checkout L24.9

You may use a different tag. Simply run “git tag -l | grep L24” to see the list of tags. (I used the latest at the time of this post). Build u-boot for OMAP4

make ARCH=arm distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

make ARCH=arm distclean

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-

At this point, you should get U-boot (u-boot.bin). get x-loader and checkout the omap4_dev branch:

cd ..
git clone git://git.omapzoom.org/repo/x-loader.git
cd x-loader
git checkout L24.9

cd ..

git clone git://git.omapzoom.org/repo/x-loader.git

cd x-loader

git checkout L24.9

N.B: Both u-boot and x-loader folders must be at the same directory level. build x-loader for OMAP4:

make ARCH=arm distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- ift

make ARCH=arm distclean

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- omap4430sdp_config

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- ift

The x-loader (MLO) should now be ready. Finally, you simply need to copy MLO and u-boot.bin files to the SD card. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting […]
