I'm trying to configure Xvnc so that it will accept multiple color depths on the same screen. We have two applications, one which is required to run in 8-bit pseudocolor mode, and another which requires a 24-bit color depth.
For what I know of `Xvnc` is that it implements a basic X11 server with roughly not options included. Hence, multiple color depths is most likely not available.
However, if you use a vnc-variant that hooks into the console and sends that info, then it relies on the effective Xserver (XFree86 such) for the X11 options and hence all should somehow work.
Hence, for you: either use one of the vnc-variants that give access to the effective X11 server on the console (like vnc.so that comes with the new version). Or you should setup 2 dedicated vnc-servers for your applications.
Somewhere in the middle, if your 24-bit-color-hongry tool effectively only uses up to 150 or 200 colors, you should be able to use that on an 8-bit device with a pre-defined colormap. Then just give both tools their own set of 8-bit colors and use that in a vnc-session. I've seen this 24-bit-app-in-8-bit-device working on a Sunworkstation but I don't recal any details...

There are ways to tell the Xvnc server that you want to use multiple pixel color depths for a screen (specify "-pixdepths 8 24" on the command line), but I am not able to get multiple visuals to accept the 24-bit depth that is required.
If I have "Xvnc :1 -pixdepths 8 24 -depth 8 -cc 3", relevant information from xdpyinfo is as follows: .. number of supported pixmap formats: 3 supported pixmap formats: depth 1, bits_per_pixel 1, scanline_pad 32 depth 8, bits_per_pixel 8, scanline_pad 32 depth 24, bits_per_pixel 32, scanline_pad 32 .. default screen number: 0 number of screens: 1
screen #0: dimensions: 1024x768 pixels (260x195 millimeters) resolution: 100x100 dots per inch depths (3): 1, 8, 24 .. number of visuals: 6 default visual id: 0x22 visual: visual id: 0x22 class: PseudoColor depth: 8 planes available colormap entries: 256 red, green, blue masks: 0x0, 0x0, 0x0 significant bits in color specification: 8 bits visual: visual id: 0x23 class: GrayScale depth: 8 planes available colormap entries: 256 red, green, blue masks: 0x0, 0x0, 0x0 significant bits in color specification: 8 bits visual: visual id: 0x24 class: StaticColor depth: 8 planes available colormap entries: 256 red, green, blue masks: 0x7, 0x38, 0xc0 significant bits in color specification: 8 bits visual: visual id: 0x25 class: TrueColor depth: 8 planes available colormap entries: 8 per subfield red, green, blue masks: 0x7, 0x38, 0xc0 significant bits in color specification: 8 bits visual: visual id: 0x26 class: DirectColor depth: 8 planes available colormap entries: 8 per subfield red, green, blue masks: 0x7, 0x38, 0xc0 significant bits in color specification: 8 bits visual: visual id: 0x27 class: StaticGray depth: 8 planes available colormap entries: 256 red, green, blue masks: 0x0, 0x0, 0x0 significant bits in color specification: 8 bits
What I need to get to is a visual that has a class of PseudoColor, depth of 8, and 256 available colors at the same time there is another visual that is a TrueColor class, depth of 24 and the large colormap entry you would expect to have.
I have been able to get Xvnc to have multiple screens (Xvnc :1 -screen 0 800x600x8 -screen 1 800x600x24), each with its correct colormap, so there MUST be a way to have it all on the same screen.
Are there any X11 experts out there who can shed some light on how this might be achieved?
