Xubuntu 12.04 LTS running on AMD X6 FX-6100

After couple of weeks i told my boss that my old hardware must be replaced. My plan was to buy hardware which would be able to serve me for testing stuff. My choice was:
CPU: AMD X6 FX-6100
RAM: Kingston 8GB HyperX Blue
Motherboard: Gigabyte GA-780T-D3L
Case: Modecom A14
Graphic card: ATi Radeon HD5450 1GB RAM DDR3

All my company runs programs which require Microsoft Windows, but i like ubuntu! So, because i don’t need any special desktop effects i have installed on that configuration Xubuntu 12.04.02 LTS. To run Windows software i have installed┬áOracle VirtualBox and then Windows 8 Enterprise Edition.

This is a second week when i am using that and everything works fine!

(X)Ubuntu 12.04 – Java SDK 7 and Google Chrome

From Oracle site download latest Java SE Development Kit 7. Installation goes like this:

  1. Download latest Java SDK
  2. Unpack it
    $ tar -xvf jdk-7u10-linux-i586.tar.gz
  3. Create directory in /usr/lib/jvm
    $ sudo mkdir -p /usr/lib/jvm/jdk1.7.0
  4. Move unpacked files into created directory:
    $ sudo mv jdk1.7.0_10/* /usr/lib/jvm/jdk1.7.0/
  5. Update your alternatives:
    $┬ásudo update-alternatives –install “/usr/bin/java” “java” “/usr/lib/jvm/jdk1.7.0/bin/java” 1
    $┬ásudo update-alternatives –install “/usr/bin/javac” “javac” “/usr/lib/jvm/jdk1.7.0/bin/javac” 1
    $┬ásudo update-alternatives –install “/usr/bin/javaws” “javaws” “/usr/lib/jvm/jdk1.7.0/bin/javaws” 1

Next thing is to create a plugins directory in Google Chrome folder:

$ sudo mkdir /opt/google-chrome/plugins

and after that a link to

$ sudo ln -s /usr/lib/jvm/jdk1.7.0/jre/lib/i386/ /opt/google/chrome/plugins/

Here you can check if your Java plugins works ­čÖé
