Ubuntu Repository

NEW PPA REPOSITORY:
The original repository was getting a bit outdated. It was trailing a few Ubuntu-releases behind and only had i386-builds. You can still use it for Hardy or manually download packages (see below) for installation on newer releases, but I'm no longer going to maintain the old repository. Instead, most packages have been moved to my personal package archive (PPA) on launchpad.net. Please check there for instructions and the newest 32-bit and 64-bit builds for Ubuntu (and Debian) Linux...

Go to the new PPA

Quick installation of the main packages:

sudo add-apt-repository ppa:levien/thbio ; sudo apt-get update
sudo apt-get install cash grind sqiv xppaut

Hardware 3D acceleration on an ATI Radeon 9600 mobile

UPDATE (2010-08-25): This article describes how to configure Ubuntu 8.04 LTS (Hardy Heron) for stable 3D-acceleration and desktop-effects with ATI R300 series (Radeon Mobility 9600 and similar) GPUs. On recent Ubuntu versions (such as 10.04 LTS) this should work out of the box, and making modifications to xorg.conf may actually introduce unwanted artefacts. Therefore if you upgrade from 8.04 LTS to 10.04 LTS you should remove your customised settings. See the description at the bottom of the article for more details...


OpenOffice.org / LibreOffice Tips & Tricks

Installing LibreOffice on Ubuntu 10.04 LTS (Lucid Lynx)

Downgrading packages using yum

In Linux-land there are two major package management systems, APT/dpkg and YUM/RPM. My favourite of the two is definitely APT, which is mostly used by Debian and derivatives such as Ubuntu. Yum is used by Red Hat and derivatives such as CentOS, Fedora and SME, and works just fine for installing packages.

LaTeX formulas in ODF and Word documents

UPDATE (2012-10-01)

OOoLatex is no longer being updated by Geoffroy Piroux. Roland Baudin has created an up-to-date fork for LibreOffice called TexMaths. To install that on a recent version of Ubuntu, first get the required packages:

sudo add-apt-repository ppa:martin-gieseking/ppa
sudo apt-get update
sudo apt-get install texlive dvipng dvisvgm
