LBX, FreeNX, NoMachine's NX: faster, significantly faster still, amazing, respectively. The latter is easy to install and configure too.

LBX (Low Bandwidth X) is an X server extension which performs compression on the X protocol. It is meant to be used in conjunction with X applications and an X server which are separated by a slow network connection, to improve display and response time. http://www.paulandlesley.org/faqs/LBX-HOWTO.html
dxpc - The Differential X Protocol Compressor * Original Author: Brian Pane <firstname.lastname@example.org> * Current Maintainer: Zachary Vonler <email@example.com> dxpc works in essentially the same way as LBX. However, to avoid having to implement an X extension and modify the X server code, dxpc uses two proxies: one that runs on the REMOTE host, like lbxproxy, and one that runs on the LOCAL host.

Think about using vncserver instead of trying to squeeze the inherently verbose X format over a serial link... there are a couple of different approaches here - one acts like MS Terminal Services where you log onto a 'virtual desktop' that is unseen on any physical display, (vncserver itself) and the other involves watching the current desktop via VNC (usually using a user-space wedge like 'x11vnc') However, a recent way to do this is using an X extension 'vnc.so' so you can immediately plug straight in and see the desktop and interact with the live session - I use this daily for remote support on a network of 30 Linux boxes :)

In my experience, as of 2006 Oct 01, having tried both over the last couple of years(?), the NoMachine version, which is now free-forever for Linux is easier to install, less buggy and faster. But a big thankyou to the FreeNX guys whose product I used for 2 years.
Simply download the packages for nclient, nxnode and nxserver, and install in that order.
dpkg -i nxproxy_1.4.0-m2-1_i386.deb nxagent_1.4.0-m2-1_i386.deb freenx_0.3.1-2_all.deb -- simple: choose built in key from nomachine -- better: choose custom key nxsetup --install OLD: nxserver --adduser ... --passwd ... ... this adds a key to /home/<user>/.ssh/authorized_keys and adds usernames and passwords into its own db which is now pointless as PAM is used...
dpkg -i nxclient_1.5.0-141_i386.deb
-- simple: client: nxclient... should authenticate via built in key (with pam username and password???) -- better: copy server:/var/lib/nxserver/home/.ssh/client.id_dsa.key to the client OLD: on client mv this key to /usr/NX/share and chmod 644 NOW: import key into client and authenticate with pam credentials..
