Greetings all,
HP/Apollo has donated a DN10000 with a 40 plane display to UNM and
I am the poor sap managing it ;^). I was wondering if anyone out there
has modified X11R4 to take advantage of the 40 plane display and do 24-
bit color on the DN10000? And in general has anyone done 24-bit color
on any display?

I'm sorry I can't answer about the DN10000, but I can hit the general question. As I recall from the Q&A session at the January X conference, it sounded as if a few vendors have done 24-bit X11 on some of their displays. I know that the HP-UX TurboSRX and TurboVRX displays do, but I don't know who the other vendor(s) was/were (sorry). I believe that it was at that meeting that Keith Packard (main server person at MIT) said that MIT hasn't done it because the cfb-type code would be too slow, and I think that for a lot of operations that claim would be true (since you'd be doing 32-bits-per-pixel ops instead of 8-bits-per-pixel, you can figure a roughly 4X decrease in performance). With hardware assisted rendering, the numbers can go up, but the cfb-type code doesn't take advantage of such hardware features. Ian Elliott
