Configuring ATI Radeon Linux drivers on Ubuntu

Download the ATI Radeon drivers ‘fglrx’ from the Synaptic Package Manager.

Edit /etc/X11/xorg.conf:

Add to ‘Section “Module”‘: Load “GLCore”

In ‘Section “Device”‘ change “ati” to “fglrx”

After restaring, check output in glxinfo – direct rendering should be ‘yes’ and ‘renderer string’ should show ‘MOBILITY/RADEON 9000 DDR Generic’

Initially I had errors running glxinfo – this post here explains the problem and provides a fixed (older?) .so file to replace one in the lates fglrx dirver.

Installing Java5 on Ubuntu Linux 6.06

The Java5 JDK has been packaged as as .deb package ready to install on Ubuntu, without jumping through hoops downloading the RedHat .rpm version and converting to a .deb with the ‘java-package’ utility.

Enable the Multiverse pacakge catalog if you haven’t already done so – in the Software Preferences utility, select ‘Add’ and then select the ‘Multiverse’ option.

You can now install via the Package Manager, or from the command line: sudo apt-get install sun-java5-jdk

Ubuntu comes with the GNU Java compiler which is enabled by default. These instructions walk you through how to select which Java version to run,and how to change between multiple versions, eg gjc to Sun Java5

Enabling root user in Ubuntu

The root user in Ubuntu by default is assigned a random password and you are not given the option to change it during install time.

To change the password in order to logon as root, use the Users and Groups tool, locate the root user, then change the password.
