I believe that my case is identical to the original message of the list and 24-bit is required. The problematic visual (the one which is not provided by the external X-server) is the following (I cite an extract from xdpyinfo on the original system):
* visual:* * visual id: 0x36* * class: PseudoColor* * depth: 4 planes* * available colormap entries: 16* * red, green, blue masks: 0x0, 0x0, 0x0* * significant bits in color specification: 4 bits* At another part of xdpyinfo, I also get the following info: *screen #0:* * dimensions: 1280x1024 pixels (342x274 millimeters)* * resolution: 95x95 dots per inch* * depths (4): 8, 12, 24, 4* Please forgive my technical ineptitude, in case I did not answer your question, but I am not experienced in this domain.
