<br>
<br><tt><font size=2>Yup.</font></tt>
<br>
<br><tt><font size=2>NX works by having its own server based "X server"
( the client in</font></tt>
<br><tt><font size=2>normal speak ) running all the time, (to keep the
session open whilst</font></tt>
<br><tt><font size=2>you are disconnected, for example) and then compressing
the session</font></tt>
<br><tt><font size=2>and displaying it remotely on your laptop.</font></tt>
<br>
<br><tt><font size=2>It does not connect to your server based gnome "X
server" like VNC</font></tt>
<br><tt><font size=2>does.</font></tt>
<br>
<br><tt><font size=2>This means that if you ever want to connect to your
session via </font></tt>
<br><tt><font size=2>FreeNX you have to have the session run via NX all
the time,</font></tt>
<br><tt><font size=2>and if you are working directly on the server you
still need the</font></tt>
<br><tt><font size=2>NX client to connect to the same session !!</font></tt>
<br>

<br>
<br><tt><font size=2>Running locally, it should only be noticably slower
if you are running</font></tt>
<br><tt><font size=2>out of memory or CPU (with the NX client running and
caching)</font></tt>
<br>
<br><tt><font size=2>Regarding the server based NX client, you can:-</font></tt>
<br>
<br><tt><font size=2>1/ Set "disable encryption of all traffic"
under</font></tt>
<br><tt><font size=2> <Configure
button><Advanced tab><Network></font></tt>
<br><tt><font size=2>2/ Set the connection to LAN under</font></tt>
<br><tt><font size=2> <Configure
button><General tab></font></tt>
<br><tt><font size=2>3/ You can experiment with cache sizes in</font></tt>
<br><tt><font size=2> <Configure
button><Advanced tab><System></font></tt>
<br><tt><font size=2>to see if using extra memory makes a difference or
if your</font></tt>
<br><tt><font size=2>setup works faster without using a cache at all.</font></tt>

<br>
<br><tt><font size=2>Then you need VNC and you have to put up with the
rescaling</font></tt>
<br><tt><font size=2>offered by your version of VNC, but try the above
suggestions first.</font></tt>

<br>
<br><tt><font size=2>Most windows server people I know use citrix on servers,
which</font></tt>
<br><tt><font size=2>works the same way as NX regarding your session (must
be citrix)</font></tt>
<br><tt><font size=2>and</font></tt>
<br><tt><font size=2>for windows desktop support etc on workstations use
tightVNC and</font></tt>
<br><tt><font size=2>have to put up with the mess if the machines are very
