What do you mean copied over? The resource.cfg (heck all the files are where needed already).. Please restore them to there orignal state.
Run the ogre Linux demos from:
ois/demos/ogre/common
First, I didn't overwrite anything, so no restoring is actually needed. After building OIS, I changed to the demos directory. I saw the ConsoleApp program there, tried it and it worked. The FFConsoleTest program did not work, but I have no force feedback device connected.

Then I saw the ogre directory, changed into it and found two programs, ActionMap and ForceFeedback. How was I supposed to know that I had to go to the common subdirectory to run the programs, when the program files also exist in the ogre directory? Anyway, I tried ActionMap, and it complained about a missing resource.cfg file, so I simply copied it (and the Media tree) from the Ogre Samples directory and changed the paths in the resource.cfg accordingly.
By the way, I now tried running them from the common subdirectory, and they worked fine.

Oh, and make sure are using the 0.6.0 release, some mouse issues were fixed. Either checkout cvs (though, anonymous cvs is heywire) using the v0-6 tag, or download the tar.gz from the file release section (from sourceforge project).
I use the 0.6.0 release.
