Comment:

Neither Xvfb nor wiki/Xdummy support bpp higher than 24/32 at present. This is what you get with Xdummy:

[  8081.079] (EE) DUMMY(0): Given depth (30) is not supported by this driver

And in the code we see:

    if (!xf86SetDepthBpp(pScrn, 0, 0, 0,  Support24bppFb | Support32bppFb))

So this driver would require some work (not sure how much) to support anything other than 24 / 32.

Until then, we could support such modes by running against a real X11 server instead of a virtual one, but this would limit us to one session per GPU at best...

As for the xpra code itself, the pixel compression would not be too much of a problem (I think vp9 supports 10bpp and even alpha channels) - though the client would require some work to take advantage of the extra colours depth.

    initial v1  
    1 I'm not sure if it's difficult or just few lines of code but in case it's quick fix it'd be nice to have 40 bit color (for Quadro) support, doesn't matter png (which supports 10bpc) or raw, whatever just anything to transport deep color. I happen to work in environment supporting 10bpc. If you care, ATI FirePro support 12bpc? if i remember well. It's ofc supported by normal X server.
