I'm seeing the same problem. I can connect successfully using xtightvncviewer 1.2.9-21, but not with xvncviewer 3.3.7-13ubuntu2

I have the same problem, on Gutsy, tried with all these packages:
xvncviewer
xvnc4viewer
xtightvncviewer

[tebeka (miki-tebeka)]

I see the same problem.

The tightvnc viewer (http://www.tightvnc.com/download.html) works fine (installed from sources).

[perpeden (perpeden)]

This may be a result of the default color settings in vnc, try this:

vncviewer FullColor=1 <ipaddress>

From the messages above, this should allow it to work for you.

[Kirby (usawebbox)]

Yes, that does fix it. Sadly, there is no way to select that option in tsclient-applet 0.150

Of course, it still means that auto-negotiation and support for lower rate modes is not working, either in xvnc4viewer or on the Mac side.

[Daniel T Chen (crimsun)]

Lowering severity due to extant workaround.

I only have issue with the clipboard...

[alan ezust (alan-ezust)]

i have the same problem with debian lenny and these clients, while trying to talk to 2 different macs using desktopsharing.

Xtightvncviewer Version: 1.3.9-4
Vinagre Version: 0.5.1-2
xvnc4viewer Version: 4.1.1+X4.3.0-31 FullColor=1
xvncviewer Version: 4.1.1+X4.3.0-31 FullColor=1

[alan ezust (alan-ezust)]

reproduced using krdc also

[alan ezust (alan-ezust)]

Current workaround is to use either

jtightvncviewer or gvncviewer

Neither of them seem to exhibit these problems connecting to macos.

[Gustav Svensson (gustav-svensson)]

Using perpeden's solution fixes the problem for me:
vncviewer FullColor=1 <ipaddress>

[Ed (classicmacintosh)]

If I remember Mac OS X's VNC server does not support 32-bit colour... thus you need to set VNC to use 16-bit colour.

I feel that patching VNC to use 16-bit colour by default should fix this issue, whilst not losing existing compatibility.

Confirming because this happens to several users.
