The +intent of this is to allow users to override values of programmatically +determined settings (such as 'Gtk/ShellShowsAppMenu') and to allow +developers to introduce new XSETTINGS for testing (without having to kill the +gnome-settings-daemon running in the session and run their own patched +version). + +The type of the overrides is 'a{sv}'. + +The key gives the full XSETTINGS setting name to override (for example, +'Gtk/ShellShowsAppMenu'). The value is one of the following: + + - a string ('s') for the case of a string XSETTING + + - an int32 ('i') for the case of an integer XSETTING + + - a 4-tuple of uint16s ('(qqqq)') for the case of a color XSETTING + +Dictionary items with a value that is not one of the above types will be +ignored. Specifically note that XSETTINGS does not have a concept of +booleans -- you must use an integer that is either 0 or 1. + +An example setting for this key (as expressed in GVariant text format) +might be: + + { 'Gtk/ShellShowsAppMenu': < 0 >, 'Xft/DPI': < 98304 > } + +Noting that variants must be specified in the usual way (wrapped in <>). + +Note also that DPI in the above example is expressed in 1024ths of an +inch. diff --git a/plugins/xsettings/fc-monitor.c b/plugins/xsettings/fc-monitor.c new file mode 100644 index 0000000..63e8712 --- /dev/null +++ b/plugins/xsettings/fc-monitor.c @@ -0,0 +1,317 @@ +/* -*- Mode: C; tab-width: 8; indent-tabs-mode: nil; c-basic-offset: 8 -*- + * + * Copyright (C) 2008 Red Hat, Inc. + * Copyright (C) 2017 Jan Alexander Steffens (heftig) + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

(As always, use of the second person "you" + * herein is plural, not singular.) + * + * EDID does not reliably give you the size of the display. + * + * Base EDID has at least two different places where you can give a + * physical size (before considering extensions that aren't widely deployed + * so whatever). The first is a global property, measured in centimeters, + * of the physical size of the glass. The second is attached to your (zero + * or more) detailed timing specifications, and reflects the size of the + * mode, in millimeters. + * + * So, how does this screw you? + * + * a) Glass size is too coarse. On a large display that cm roundoff isn't + * a big deal, but on subnotebooks it's a different game. The 11" MBA is + * 25.68x14.44 cm, so that gives you a range of 52.54-54.64 dpcm horizontal + * and 51.20-54.86 dpcm vertical (133.4-138.8 dpi h and 130.0-139.3 dpi v). + * Which is optimistic, because that's doing the math forward from knowing + * the actual size, and you as the EDID parser can't know which way the + * manufacturer rounded. + * + * b) Glass size need not be non-zero. This is in fact the usual case for + * projectors, which don't have a fixed display size since it's a function + * of how far away the wall is from the lens. + * + * c) Glass size could be partially non-zero. Yes, really. EDID 1.4 + * defines a method of using these two bytes to encode aspect ratio, where + * if vertical size is 0 then the aspect ratio is computed as (horizontal + * value + 99) / 100 in portrait mode (and the obvious reverse thing if + * horizontal is zero). Admittedly, unlike every other item in this list, + * I've never seen this in the wild. But it's legal. + * + * d) Glass size could be a direct encoding of the aspect ratio. Base EDID + * doesn't condone this behaviour, but the CEA spec (to which all HDMI + * monitors must conform) does allow-but-not-require it, which means your + * 1920x1080 TV could claim to be 16 "cm" by 9 "cm". So of course that's + * what TV manufacturers do because that way they don't have to modify the + * EDID info when physical construction changes, and that's cheaper. + * + * e) You could use mode size to get size in millimeters, but you might not + * have any detailed timings. + * + * f) You could use mode size, but mode size is explicitly _not_ glass + * size. It's the size that the display chooses to present that mode. + * Sometimes those are the same, and sometimes they're not. You could be + * scaled or {letter,pillar}boxed, and that's not necessarily something you + * can control from the host side. + * + * g) You could use mode size, but it could be an encoded aspect ratio, as + * in case d above, because CEA says that's okay. + * + * h) You could use mode size, but it could be the aspect ratio from case d + * multiplied by 10 in each direction (because, of course, you gave size in + * centimeters and so your authoring tool just multiplied it up). + * + * i) Any or all of the above could be complete and utter garbage, because + * - and I really, really need you to understand this - there is no + * requirements program for any commercial OS or industry standard that + * requires honesty here, as far as I'm aware. There is every incentive + * for there to _never_ be one, because it would make the manufacturing + * process more expensive. + * + * So from this point the suggestion is usually "well come up with some + * heuristic to make a good guess assuming there's some correlation between + * the various numbers you're given". I have in fact written heuristics + * for this, and they're in your kernel and your X server, and they still + * encounter a huge number of cases where we simply _cannot_ know from EDID + * anything like a physical size, because - to pick only one example - the + * consumer electronics industry are cheap bastards, because you the + * consumer demanded that they be cheap. + * + * And then your only recourse is to an external database, and now you're + * up the creek again because the identifying information here is a + * vendor/model/serial tuple, and the vendor can and does change physical + * construction without changing model number. Now you get to play the + * guessing game of how big the serial number range is for each subvariant, + * assuming they bothered to encode a serial number - and they didn't. Or, + * if they bothered to encode week/year of manufacturer correctly - and + * they didn't - which weeks meant which models. And then you still have + * to go out and buy one of every TV at Fry's, and that covers you for one + * market, for three months. + * + * If someone wants to write something better, please, by all means. If + * it's kernel code, send it to dri-devel at lists.freedesktop.org and cc me + * and I will happily review it. Likewise xorg-devel@ for X server + * changes. + * + * I gently suggest that doing so is a waste of time. + * + * But if there's one thing free software has taught me, it's that you can + * not tell people something is a bad idea and have any expectation they + * will believe you. + * + * > Obviously in a multi-screen set-up using Xinerama this has the potential + * > to be a Hard Problem if the monitors differ greatly in their DPI. + * > + * > If the major resistance is over what to do with older hardware that + * > doesn't have this data available, then yes, punt; use a hard-coded + * > default.
