LyX，所见即所得--利用Latex来排版的文件编辑软体

LyX是一个“所见即所指”（what you see is what you mean）的利用LaTeX来排版的文件编辑软体。相对于其它标榜所见即所得的编辑器而言，LyX标榜只显示你真正的关心的内容。

以及特别在Ubuntu下安装的步骤：http://wiki.lyx.org/LyX/LyXOnUbuntu#toc3 ，或者直接如下

1.Installing

If you already have a repository version of LyX installed, you will have to remove it:

sudo apt-get remove lyx (remove your repository version)
sudo apt-get autoremove (remove repository dependencies)

If you don’t do this, the fourth step that follows may fail.

2.Do the following:

sudo add-apt-repository ppa:lyx-devel/release (add the PPA for the 'release', i.e. stable, compilation)
sudo apt-get update (update so that apt is aware of the new PPA)
sudo apt-get install lyx (install from the PPA)
lyx (run LyX)
