[FreeNX-kNX] Disable shared memory and shared pixmap

If you want to disable shared memory via the setting
in nxclient

<Configure (button)><General (tab)><Display (section)>
<Use custom settings (checkbx)><Settings (button)><performance>

you probably need to update your nxnode to pass it to
nxagent

eg. ubuntu/fedora pin shmem=1 ignoring nxclient
so
you will need to edit nxnode and add :-

        noshpix=$(getparam noshpix)
        shpix=$(getparam shpix)
        noshmem=$(getparam noshmem)
        shmem=$(getparam shmem)

to the list at the beginning of  startsession()
and
update the bit which looks almost like:-

cat << EOF > "$USER_FAKE_HOME/.nx/C-$sess_id/options"
nx/nx,${keyboard:+keyboard=$keyboard,}${kbtype:+kbtype=$kbtype,}${kbload:+kbload=$kbload,}${keymap:+keymap=$keymap,}${geometry:+geometry=$geometry,}${client:+client=$client,}${resize:+resize=$resize,}${CACHE}${IMAGES}${PACK}link=$link,nodelay=$nodelay,type=$realtype,${clipboard:+clipboard=$clipboard,}${composite:+composite=$composite,}product=LFE/None/LFEN/None,${noshmem:+noshmem=$noshmem,}${shmem:+shmem=$shmem,}${backingstore:+backingstore=$backingstore,}${noshpix:+noshpix=$noshpix,}${shpix:+shpix=$shpix,}${ACCEPT}cookie=$proxy_cookie,id=$sess_id,samba=$samba,${sync:+sync=$sync,}${cups:+cups=$cups,}${keybd:+keybd=$keybd,}${aux:+aux=$aux,}${
http:+http=$http
,}${rdpcolors:+rdpcolors=$rdpcolors,}${rdpcache:+rdpcache=$rdpcache,}${fullscreen:+fullscreen=1,}${menu:+menu=$menu,}media=$media:$display
EOF

 . . . to pass them to nxagent (note that my version has been rationalised 
a little too)

You don't tell me what distro or rpm /deb you are using so I can't post a 
diff for you to test.

Good luck !!! Let us know how you get on . . . .
