Sounds like a good idea.
Also, Compiz/Fusion (or the KDE equivalent) would also need disabling
on full screen (as some apps have issues with it), and restore when
leaving full screen (if it was previously enabled). This should be
handled on the Windows side from the DWM APIs. IIRC, there is a DBUS
protocol which enables this to be done on the Linux side (which should
be appropriately #if HAVE_DBUS'd).
Searching on Google, it looks like the screensaver protocol is also
dbus (e.g. http://bugs.archlinux.org/task/7002?getfile=1123 for a
patch that adds this support to mplayer). It also looks Gnome specific
(FD.o does not appear to have a screensaver specification). I could
not see what KDE uses (if it is a C++ API it will be unusable for
Wine, although http://lists.mplayerhq.hu/pipermail/mplayer-users/2002-March/011941.html
provides a script that calls various helper programs, so not sure how
useful it is).
Does anyone know if the Gnome protocol is stable, or if it is likely
to be dropped/changed? Also if it is supported by KDE3/4?
