quick update on this: i have a 30-bit setup now (display port, dell U2713H, nvidia quadro 5800, elderly model but apparently the first one to actually serve 30-bit through to the monitor).
x11 seems to work just fine, i can push 10-bit colour to the monitor and get smooth gradients, yay. gtk + cairo seems to work, kind of. cairo gradients seem to be drawn in 8-bit, and manually drawing a bunch of rectangles gives me spot on super smooth colour, but is terribly slow (like 30sec for one drawn buffer instead of 0ms for 24-bit). we may need to look into cairo sources or direct xorg buffer blitting (non portable). btw a surprising lot of my `desktop software' still works just like it did before. okay, that's mostly the terminal, but also firefox, thunderbird, gimp kind of (icons look broken, otherwise fine). cheers, jo On Thu, Jan 14, 2016 at 7:37 PM, johannes hanika <hana...@gmail.com> wrote: > On Fri, Jan 15, 2016 at 4:56 AM, Moritz Moeller <virtualr...@gmail.com> wrote: >> On 13/01/16 08:29, Roman Lebedev wrote: >>> >>> Hello, lists. >>> >>> darktable's support for 30-bit color depth was again brought up in IRC >>> channel yesterday. >>> >>> As far as i'm aware, none of us developers has the hardware (videocard >>> that supports >>> 30-bit output + 30-bit monitor), so we have no means to test and >>> develop needed changes. >> >> >> Isn't Johannes working @ Weta?
