Here how far I got so far with monogame and ubuntu 13.04.
Remember I am not a linux boy. See previous article about monogame and windows.
1-install mono complete 2.1 (from ubuntu.org)
2-install mono develop 3.04 (from ubuntu store)
3-donwload and compile opentk (not sure this part is needed)
4-install monogame mpack (templates) for mono develop
5-sudo apt-get install libopenal1
6-sudo apt-get install libsdl1.2debian
7-sudo apt-get install libsdl-mixer1.2
8-test a monogame c# project
At this point you can build a c# project with monogame in ubuntu 🙂
Now for vb.net projects, I managed to create a new project but could not compile it (missing vb compiler?)
I guess I might have to look for more recent monodevelop/mono source (maybe from opensuse?)
Tip : for vb.net projects, change the file format to use when creating new projects to MSBuild (Visual Studio 2008) instead of the default MSBuild (Visual Studio 2010) From Preferences > Load/Save
