HowTos/VNC

From OpenZaurus

This is a short HowTo explaining remotely controling a Zaurus (or something else!) through VNC.

This allows you to to see the display of the Zaurus through a system running the VNC client and use its mouse and keyboard to control the Zaurus.

Apart from being cool and fun, and one to take screenshots, this can be useful for typing a lot of text into graphical applications. (Though on SL-C3000 at least, you can attach a USB hub and USB keyboard. The key mapping is a bit weird, though).

For console applications it's better to use an ssh session! ssh root@zaurus_ip_address

On Zaurus Side :

Install fbvncserver

When you want to launch vnc server, from the console run fbvncserver thus:

fbvncserver -fancy

or

fbvncserver -double

On remote side :

Launch VNC client thus:

vncviewer -encoding "raw" zaurus_IP_address:0

Why "-encoding raw"? Dunno. Perhaps because fbvnc (Frame Buffer VNC) server, not the usual vnc server, is running on the Zaurus. The normal vnc server intercepts X and windows commands for efficiency, i.e. small regions of the screen are transmitted. FB VNC probably just intercepts changes to the frame buffer memory as a whole and compressing in entirety every time it changes is slow.

Enjoy!
