I would just use vnc over wifi. Worked fast for me. If it doesn't work make sure the firewall on your computer and the firewall on your router are set to allow the port for vnc.

Not as a full monitor. But if you are running Linux on the Laptop. You can set the DISPLAY of any application you wish from the laptop to display on the monitor.

You would need both the laptop and monitor to be networked either wifi or blue tooth.

Then set the 770 or n800 such that when you launch certain apps it ssh -X -e s into the Laptop and runs on the laptop.

-e will select the program you wish to run -X will tunnel its output back to the device.

I do similar things with my linux boxes at home all the time. It is just a matter of getting the devices networked efficiently. You can then run wine or vmware on the laptop and do the same with windows apps etc

The problem with rdesktop or VNC is that you are actually taking over the remote computer. If the resolution is greater than 800 x 480 on that machine you have a lot of scrolling to do to interact with the desktop.

HumanPenguin's got it right with forwarding X to the tablet. I have been using this method to control Rhythmbox on my home PC which outputs its audio to my wireless home speaker system. By forwarding X from the desktop to the tablet, I am free to create playlists, next track, rate, submit tracks to last.fm, fetch lyrics, etc all from tablet, anywhere inside or outside of the home. And since X is so well thought out, resolution is not an issue. The application is automatically resized to the size of the tablet's display. To me, this is a much more elegant solution than rdesktop or VNC.

And the extra cool feature. When you park your car in front of you house/appartment you can have it connect to your home wife. Walk in press a button on your desktop linux PC and have the app open their.

Sit at you desk drinking coffee and watching breakfast news while you choose your playlist for the long morning commute.

Move appropriate maps to your navigation system before a long trip.

Or what ever else you choose to do with your car PC.

Yeah XWindows got it right all those years ago. At the time it was planned to support a mainframe mentality with small X Terminals displaying the app but the huge data centric software running on the big mainframe.

Now I have 4 PCs at home with 1x22 inch monitor. And just run the apps where I like. Windows RDesktop/VNC just dosent cut it.

To avoid the size issue pointed out above, and to improve performance...
1. connect via wifi
2. launch vncserver -geometry 800x480 on the notebook (running some form of *nix)
3. connect via vncviewer in fullscreen mode on the Nokia

The note about some form of *nix is because I don't think that the windows version of VNC can initiate a new session, where you can have as many as you want (at whatever size you want) on *nix systems (within memory and CPU constraints, obviously).

If security is a concern, tunnel the vnc session via ssh (from the Nokia) using -L 5901:localhost:5901 (if running vnc using display :1) and use -c blowfish-cbc to improve performance (but not -C!). You will then point your vncviewer at :1 (or localhost:1) and let ssh tunneling handle the connection.

Note that I have not tried this yet (may tonight) as I just got my 770 recently, but I do tunnel vnc through ssh whenever I need to use it.
