Thanks for your explanations, Grant. Though some it raises more questions, in case you or anyone else care to elaborate.

I thought the whole point of specifying the veiwer depth was to reduce bandwidth. Why would one want to reduce the viewer depth without also having it reflected in the communication? For the thin client model, the (naively) reasonable thing to do is to get server to quantize each color plane to the coarseness requested by the viewer depth. Obviously something I'm missing here. > What is happening in your case is that your local system's default visual is > 8-bit pseudo colour, and a 24-bit pseudo-colour visual doesn't exist; the > viewer, in that case, will use the only available pseudo-colour visual > (8-bit) and behave as if the -bgr233 command line option was supplied. This would certainly explain the "truant" viewer behaviour, though I was under the impression that the display is *not* pseudocolor unless the server is started with "-cc 3". I ran into a problem with CAD tools for IC layout because it wanted a pseudocolor visual, and someone on the VNC list rightly suggested that the "-cc 3" was required. I'm assuming that "visual" is a property of the server display only, in particular the display created by vncserver. > If the server has a true colour visual available, this command line should > do what you want: > vncviewer -depth 24 -truecolour _server_:_num_ Just something I want to clarify here. By server, I presume you mean vncserver rather than host machine for the vncserver? Because for VNC, it seems that server and display and visual are all one and the same. A server cannot have more than 1 display, some being true color while others are not. Assuming they are synonymous, then it seems the existence of "-cc 3" and "-truecolour" specify the same thing, except one is on the server side and the other is on the viewer side....right? Anyway, you've supplied quite a bit of interesting and important detail. Thanks.
