Xtightvncviewer

xtightvncviewer is a very fast and light VNC viewer that you can use to access remote machines, including virtual machines, from underpowered computers like Raspberry Pi. But there's a hard-to find setting that you need in order to make it work well, which is setting the 'grabKeyboard' Xresources setting. After scouring the net for this info several times, I decided to make a copy here...

In the client's computer, we install the viewer with:

sudo apt-get install xtightvncviewer

To avoid problems with the keyboard in full screen mode (who owns the keyboard, the client's desktop or vncviewer?) we shall give the keyboard to vncviewer. To do that we just type:

echo "Vncviewer*grabKeyboard: true" >> ~/.Xresources
xrdb -merge ~/.Xresources

in order to define the option grabKeyboard in the /home/user/.Xresources file.

We are ready to login using

xtightvncviewer -fullscreen -x11cursor 192.168.1.6:1

(replace with your own server's IP address as appropriate).

When you're in fullscreen mode, use F8 to bring up a menu which include "Quit Viewer". If F8 isn't working for you, you may have a problem with the "grabKeyboard" option as described above.

The option -x11cursor shows a more beautiful pointer for the mouse.

Good settings for connecting to a remote server

ssh -C -o CompressionLevel=9 -L5991:localhost:5991 my.server.example.net
xtightvncviewer -fullscreen -depth 16 -compresslevel 8 -quality 3 -encodings "tight copyrect hextile zlib corre rre raw" -x11cursor localhost:5991

(you probably you want to type these into two separate console windows).

This xtightvncviewer is much faster than the nice GUI alternative, Remmina on Raspberry Pi.

However, the frustration with xtightvncviewer is that it doesn't pass through the SHIFT-TAB keystroke correctly -- apparently there is a bug somewhere.

TigerVNC

TigerVNC looks like a more actively maintained VNC viewer, and it's supposed to work on Raspberry Pi. However it seems difficult to get it running, since FLTK 1.3.3 is not available easily on Raspberry Pi via Raspbian.
