I run Lubuntu 12.04 and after several terrible experiences with libre office I downloaded core and have not touched it since april. I find kile ok and have been learning to use that and writing with latex.
I am hoping there's a mind mapping program that I could use that is not too "bubbly" but most importantly can handle maths (i.e. latex). I don't need it to be able to integrate with kile but anything extra is a bonus! Tips?
Edit: The latex is needed for writing mathematical equations.
Edit: I thought they were all useful suggestions but on balance, the selected answer was my personal favourite out of them. Though it was tough to decide. Dia particularly does look like a good shout with ekee.

Have you seen: https://tex.stackexchange.com/questions/2847/mind-maps-in-latex and https://tex.stackexchange.com/questions/44112/mindmapping-with-latex ?
Both suggest http://www.texample.net/tikz/
http://www.texample.net/tikz/examples/feature/mindmaps/
...although the provided mindmaps feature is quite "bubbly"
As far as handling Maths:
