You mean emacs itself? It's more if you were running emacs on a
motif/cde desktop (or maybe just one with an xclipboard hanging about).
** What desktop environment (KDE, GNOME, XFCE, etc.), if any, are you using?
** Come to think of it, what does this:
(x-selection-exists-p 'CLIPBOARD_MANAGER)
return in your emacs?
GNOME - and apparently now recent XFCE - do actually have tiny clipboard
managers by default (embedded in gnome-settings-daemon and
xfce4-settings-helper respectively), but AFAIUI they shouldn't be
problematic like motif-era ones: Nowadays there is a protocol [1] for
clients to ask a clipboard manager only at client exit time to copy the
clipboard content and take over clipboard ownership from the client, to
persist the clipboard after client exit, and those managers are about
supporting those clients. I only recently learned of the XFCE one and
haven't really looked at it yet, though.
Actually, I think emacs is not doing its part of [1], though it
shouldn't typically have negative effects except when you try to paste
after copying in emacs and then quitting, so not directly related to
your problem. But I'm now looking at that "Clipboard managers are
encouraged to use this information to support legacy clients" line in
[1] - maybe there might be a clipboard manager out there that grabs
clipboard contents from "legacy clients" eagerly but avoids pestering
the clients that indicate their support of the spec. That would mean
even "legacy client" clipboard contents wouldn't lost when they exit
...but "legacy client" performance would be degraded.
