I'm writing a program that will run on both Linux and Windows. Windows
has the registry but that wont work with Linux.

I want one type of settings storage that works on both systems. Is
this possible?

On the Misc page of the Component Palette there are two components
that you may want to explore:
TIniPropStorage
TXMLPropStorage
The example for mru storage may also give you some pointers. It uses
TIniFile:
...\lazarus\components\mrumenu\mrumanager.pp

look also at Component Palette->System->TXMLConfig
http://wiki.freepascal.org/xmlconf

I always use T*PropStorage (mostly TIniPropStorage because using XML
as configuration makes it difficult to edit by hand) as they are the
real RAD style of doing this. Very easy to use and easy to add custom
values as well.

Is it possible to work with Stream instead of File in TPropStorage ?
I want to save/restore settings using database

QuoteIs it possible to work with Stream instead of File in
TPropStorage ?I guess not, after all they're concrete classes. Perhaps
you can implement a db backend descendant for TFormPropertyStorage
(base class for TIniPropStorage and TXMLPropStorage, say
TDBPropStorage or something.
