You're running X. That'll take up a lot of memory all by itself.
try running "top" and then hit "M" to sorty by Memory usage. The most
interesting columns are RES and SHR (Resident memory size and Shared
memory).
Ordinarily people see that "Free" is very small but have a large
"Buffers" value...but 256MB isn't that much by modern standards and
X/Gnome/KDE are memory pigs.
My laptop for comparison:
mort@socrates:~$ free
total used free shared buffers cached
Mem: 906552 868300 38252 0 37612 375116
-/+ buffers/cache: 455572 450980
Swap: 979956 1128 978828
900MB of ram, 38MB free, but 400MB of that is page cache. This memory
is easily freed by the kernel should I start new applications.
