You are a Ubuntu user who wants the use LaTeX2e and miss your Eclipse 3.6 (Helio), what should you do?

Install LaTeX2e

You must at least install the texlive package to have a working LaTeX in Ubuntu.

You may optionally consider installing these packages too:

• texlive-full. This installs all the packages in the TeX Live distribution. You need extra nearly 1.5GB to hold all of them!
• latex-beamer. Excellent for creating presentations.
• texpower. Excellent for creating dynamic online presentations.
• texlive-fonts-extra. A large collection of font packages.
• texlive-latex-extra. A large collection of add-on packages for LaTeX.

Install Eclipse

As of this writing, the latest version of Eclipse package included in the official Ubuntu repositories is 3.5.x (Galileo). If you want to use the latest Eclipse 3.6.x (Helio), then

1. Visit http://www.eclipse.org/ and grab the latest version of Eclipse, which would be in .tar.gz format. Grab a package variant that suits you most.
2. Extract the package to a folder, say your home directory or your Desktop.
3. Create a shortcut on your desktop or your gnome panel to the 'eclipse' executable, using the 'icon.xpm' icon. There you go!

To add LaTeX support to the Eclipse IDE, you can use the TeXlipse plugin.

1. Open Eclipse.
2. Select Help > Install New Software....
3. Click Add..., and fill in the Name and Location fields with TeXlipse and http://texlipse.sourceforge.net respectively. Click OK. Eclipse should then visit the repository to fetch the software available.
4. Select TeXlipse, click Next, read and accept the license agreement, click Finish, and wait for the installation to complete. Restart Eclipse for the plug-in to take effect.

A few more tips:

• While in Eclipse, select Window > Preferences > Texlipse > Viewer Settings. Remove the entry 'none ()' (Why is it there?). You can create a new PDF viewer by filling the fields 'Viewer name', 'Viewer command', and 'Viewer arguments' with 'evince', '/usr/bin/evince', and '%file' respectively. Add or remove other viewers to suit your usage.
• Official User Manual of TeXlipse. It is good to spend a few minutes to read through the 'Editor features' section.
