mint / cinnamon equivalent of ~/.xsession script ?

[bjd-pfq]

Does Mint Cinnamon have an equivalent to the $HOME/.xession login session script
(or anything that is functionally equivalent)?

I fiddled with an ~.xsession script, but alas, it appears not to be run.

I want to set some user specific keycodes in it; under these circumstances I have
no business of setting a 'startup' program, just a script that gets run as soon as the
specific user logs in.

And no -- let' not assume at all that the user is running a terminal with an inter-
active shell.

Thank you.
