With this amount of RAM, even
Xubuntu won't run well (using swap should get you there, but it won't perform) - if you can't get to 256MB (which, in turn, would be plenty), I'd recommend using
CrunchBang or some other flavour of
Ubuntu/
Debian that uses a minimal GUI. There are other minimal, non-
*buntu distributions you might want to try;
Tiny Core or
Puppy come to mind (there are, of course and as always, others).
Debris 1.7.0 is still beta, but you can boot it with
Openbox - you shouldn't have any troubles using that (if it boots okay). If you need support, we can do that. To assess your machine fully, the output of
lspci (and, possibly
lshw - comes with
*buntu - or
hwinfo) would help. A non-GUI way to check out your box is
Finnix.
