Yes, that's one way.  What was happening (I think) is that your scheme
buffer wasn't being recognised as a MIT-scheme one. In case you ever
want to use more than one scheme with Geiser, possible alternative
settings are discussed in the manual:

In Geiser there is no *scheme* buffer where one evaluates expressions
(if that's what that buffer is, I've never used Edwin). The evaluation
results are also displayed in a buffer called *Geiser Debug*, but only
for the last evaluation.

I've never used Edwin's debugger, but I am pretty sure it
doesn't. Geiser MIT support is basic (I think, I am not its author, but
it hasn't been updated in years), and my understanding is that it
delegates to the REPL for debugging operations. That's a common trait
accross most implementations, to be fair.

Hope this helps,
