| duflu | RAOF: I take it an Android backend (or stub) for subpixel is coming? | 02:38 |
|---|---|---|
| duflu | Or not required? | 02:38 |
| duflu | Maybe x11 too | 02:39 |
| duflu | Awesome. Kernel 4.7 fixes my black screen by turning it into an equally plain orange screen | 03:34 |
| RAOF | duflu: Nested is up next. Android already sets it to _unknown, which might be as good as we can do? | 04:40 |
| duflu | RAOF: I would hope Android can do better. Will grep later. Also x11 should be able with xrandr info..? | 04:47 |
| RAOF | Yup. X11 should be reasonably easy. | 04:47 |

| duflu | RAOF: I can't find any such option for Android/HAL... Probably just as well while unity8 does client-side screen rotation, which would need work in that case | 05:59 |
| RAOF | unity8 could certainly make the appropriate changes. | 06:00 |
| RAOF | Of course, that requires the nested platform to do the right thing, which it doesn't at the moment :) | 06:00 |
| duflu | RAOF: I think it's mostly desktop monitors that U8 just isn't ready for | 06:00 |
| duflu | "low" DPI | 06:01 |
| RAOF | Indeed. | 06:01 |
| RAOF | Sub-400DPI :) | 06:01 |
| * duflu is reminded to investigate FRC | 06:01 | |
| duflu | again | 06:01 |
| RAOF | FRC? | 06:04 |
| duflu | RAOF: I think it's also known as DRM_MODE_DITHERING_* (https://en.wikipedia.org/wiki/Frame_rate_control) | 06:05 |
| RAOF | Oh, temporal dithering? | 06:05 |
| duflu | Yes | 06:05 |
| duflu | RAOF: I noticed recently Macbook Airs still need it | 06:05 |
| duflu | In 2016 just as they did in 2010 :P | 06:05 |
| RAOF | Seriously? I thought Apple tended to ship non-terrible hardware. | 06:06 |
| duflu | Yep, seriously. | 06:06 |
| duflu | It looks extra bad in Ubuntu like spatial dithering. I think we need to flip a switch | 06:07 |
| RAOF | Yay! Trade colour terribleness for 30Hz flicker! | 06:08 |
| duflu | Yep... and I only just convinced John Lea to stop shipping pre-dithered wallpaper | 06:08 |

| duflu | RAOF: What was it you said about relating surfaces to output info before? I have a plan, but don't want to conflict if you have one | 08:04 |
| RAOF | duflu: Pass a MirOutput* as a part of the surface-output event. | 08:43 |
| duflu | RAOF: That's won't work if you need to abstract it to a non-real MirOutput | 08:43 |
| duflu | ie. clone mode or overlapping multiple outputs | 08:44 |
| RAOF | ?? | 08:44 |
| duflu | So you should probably wait for my general solution | 08:44 |
| duflu | Or go have dinner... | 08:44 |
| RAOF | True, but overlapping outputs don't make sense, and clone mode you can happily pick whichever you choose. | 08:45 |
| duflu | RAOF: In clone mode, two physically different arrangements should surely be generalized to disabling sub-pixel? | 08:46 |
| duflu | Similarly I need to proxy frame timing info | 08:46 |
| duflu | So it's not that we should say a surface is on output X, but the common traits of the outputs it is on are A,B and C | 08:47 |
| duflu | RAOF: I meant a surface "overlapping" multiple outputs. In such a case what is its subpixel arrangement, and frame interval, and physical resolution etc | 08:53 |
| duflu | The answer may not match any 'real' output | 08:53 |
| RAOF | In such a case, you pick one output. | 08:59 |
| RAOF | (Specifically, you pick the output with the highest scale factor ☺) | 09:00 |
| duflu | RAOF: Yeah I get that we can survive with that compromise. And in the single monitor case the answer is absolutely correct. I'm just trying to future-proof | 09:02 |
| RAOF | Surfaces should generally span multiple outputs only transiently, and you can't render them correctly anyway. | 09:03 |
| duflu | RAOF: I used to believe that. Till we were asked to do a monitor "wall" project | 09:03 |
| duflu | One surface, many monitors | 09:04 |
| duflu | Although in that case everything except the phase of display would match | 09:04 |
| * duflu now remembers what he was looking at | 09:05 | |

| RAOF | For a video wall wouldn't you just do multiple surfaces? | 10:30 |
| RAOF | Or, alternatively, multiple buffer streams in a single surface. | 10:30 |
| * ogra_ would just make vlc work :P | 10:34 | |
