Here is how to get vim-latexsuite working on ubuntu

1. DON'T download the latex-suite file from http://vim-latex.sourceforge.net/ and unzip into ~/.vim/. It just simply doesn't work because vim-addons cannot find it, even if ~/.vim/ is in the runtimepath of vim. I don't know why.
2. USE sudo apt-get install vim-latex to let ubuntu install it for you. Also do sudo apt-get install vim-addons-manager if you haven't.
3. sudo vim-addons -w install latex-suite
4. vim-addons: You should see

#name User Status System Status
latex-suite installed(or removed, doesn't matter) installed
- put your own tex.vim file in /usr/share/vim/addons/ftplugin/
- In .vimrc, add:

set runtimepath+=/usr/share/vim/addons
filetype plugin on
set grepprg=grep\ -nH\ $*
filetype indent on
let g:tex_flavor="latex"

1. you will see an error involved with remoteOpen.vim. I eliminated those error by commenting out the specific lines in remoteOpen.vim
