You have already changed Emacs from accepting both MOD4 and SUPER_MASK
as its Super key modifiers to only accepting SUPER_MASK. I imagine this
response is born of more than just this issue but I would not let it
cloud an easy solution.
GTK 3.24.33 still accepts Mod2-5 masks, recognizes them separately from
the virtual modifier masks, and unlike the x11 implementation does not
contain the logic to set convert Super_L or Super_R to GDK_SUPER_MASK.
So what you have done is actually held Emacs to GDK's x11
implementation and documentation rather than looking at the code itself.
https://gitlab.gnome.org/GNOME/gtk/-/blob/3.24.33/gdk/wayland/gdkkeys-wayland.c#L249-316
https://gitlab.gnome.org/GNOME/gtk/-/blob/3.24.33/gdk/x11/gdkkeys-x11.c#L396-398
If the PGTK branch is meant for "alternative window systems available on
GNU/Linux and some Unix systems, such as Wayland" then I do think there
should be more consideration taken compositors that do not share
Mutter's workaround. Had you been using any other compositor, surely you
would not have made this change. Perhaps even filing a bug yourself.
This will be my last comment on the matter as I don't think its
productive for either of us to belabor our points.

First of all, the GDK_MODN_MASKs (aside from GDK_MOD1_MASK) are simply not set on Broadway, the other GDK backend that we try to support. Secondly, nothing is guaranteed about the behavior of the real modifier masks after GDK_MOD1_MASK. We cannot assume it means Super at all, since it is not documented to mean that. What if GDK changes its meaning in the future? Or the Wayland compositor developers? I am not going to settle for non-solutions (or half-solutions) like what you proposed, at least unless the GTK developers still haven't fixed this by the time Emacs 29.1 is released. > GTK 3.24.33 still accepts Mod2-5 masks, recognizes them separately > from the virtual modifier masks, and unlike the x11 implementation > does not contain the logic to set convert Super_L or Super_R to > GDK_SUPER_MASK.

Nowhere in the documentation for GdkModifierType does it say that the automatic mapping from real modifiers to virtual modifiers is X11-specific, so this is clearly a GTK bug. I'm pretty sure GTK accelerators that specify <Super> as a modifier will not work on those other Wayland compositors either, if what you say is true. > If the PGTK branch is meant for "alternative window systems available > on GNU/Linux and some Unix systems, such as Wayland" then I do think > there should be more consideration taken compositors that do not share > Mutter's workaround.

I would still have made this change and then proceeded to ask someone else to report a GTK bug. I can't do that myself, since GNOME has been persistently been making it more and more difficult to report bugs without registering an account on whatever platform they currently use for bug reports, and putting up with the associated e-mail spam. But I don't use any other Wayland compositors, so that point is moot. ^ permalink raw reply [flat|nested] 48+ messages in thread

I'm experiencing the same issue here. My super key no longer registers,
even using emacs -Q. However, I find it begins from the commit changing
to GDK modifier masks 1c1ae6ba802cc5813fa6f8f90f21050aae6bb459. I've
tested this with the following specs:

Neither of the WMs I mentioned use GNOME Shell, but they do both use wlroots. Looking into this, it seems that any wlroots based Wayland compositor will use GDK_MOD4_MASK as Super.

GDK_SUPER_MASK is a "virtual modifier" mask. The entire point of that change was to rely on GDK to compute the correspondence between real modifiers and virtual modifiers instead of doing it ourselves, since a real modifier can mean any number of virtual modifiers and vice versa. Hard-coding the meaning of GDK_MOD4_MASK would be a step backwards. This seems to either be a bug in wlroots or GDK, so I suggest that a bug be filed with their developers. ^ permalink raw reply [flat|nested] 48+ messages in thread

It does not seem to be a requirement of GTK 3.2 or XKB to send virtual modifiers. The only compositor I have come across that actually sends a virtual modifier is mutter/GNOME. Neither wlroots nor Weston, the Wayland reference implementation, send them. I'm unsure about Plasma, but I believe this highlights an issue with the development of pgtk, if it is meant to be targeted towards wayland users it should be tested against more than just one compositor. > Hard-coding the meaning of GDK_MOD4_MASK would be a step backwards.

I have spoken with devs of wlroots & wayland over IRC and they seem to agree that it is not necessary.

The reason this works is because mutter sends additional virtual modifiers. You can see more here: https://gitlab.gnome.org/GNOME/mutter/-/commit/0fa9751b3144aef5faaca1ad381b6f86b5f30994. It is not GDK that is responsible for this. Further, since this is not required, I don't think its proper to deem it a bug.

Though still not fully explicit. https://gitlab.gnome.org/GNOME/gtk/-/blob/main/docs/reference/gtk/migrating-3to4.md#adapt-to-changes-in-keyboard-modifier-handling. Your change seems to have removed a fallback in case there were no virtual modifiers and reverses the previous logic: previously: if a virtual modifier exists equal to GDK_SUPER_MASK then super_mod_mask = GDK_MOD4_MASK, if it does not equal GDK_SUPER_MASK then it just passes the state & current value.

I recently updated and ran into this issue. From the discussion in this thread, I really don't understand why this change was made.

It is to prevent errors when Mod4 is _not_ the super key. Very common on X (where Mod4 is commonly Hyper), and in fact it is caused by Mod4 not being part of the Super virtual modifier in the compositor's XKB configuration. The conclusion I eventually came to is that the problem lies in the XKB configuration of the Wayland compositor in question (namely, Sway), and not Emacs nor GDK. It works with GNOME Shell and kwin because they set up their keyboards with the correct virtual modifiers by default. So what I'd recommend is to start an X server where the Super key does work, run: xkbcomp $DISPLAY name/of/xkb/file.xkb and then use that file with Sway. ^ permalink raw reply [flat|nested] 48+ messages in thread

I can attach the full .xkb file that xkbcomp generated if you like, but it's the default which you get from the following under the v2.34 xkeyboad-config files. xkb_keymap "my_dvorak_super" { xkb_keycodes { include "evdev" }; xkb_compatibility { include "complete" }; xkb_types { include "complete" }; xkb_symbols { include "us(dvorak)+pc(pc105)" }; }; Specifically, when I use the same .xkb file under X I get that emacs interprets the physical keycode <RWIN> as Super whereas under wayland with sway, emacs does not respond to <RWIN>. The relevant lines from the xkb_symbols section are key <RWIN> { [ Super_R ] }; modifier_map Mod4 { <RWIN> }; Reading through the links that Trey sent in previous emails to the gtk source which handles modifier keys in x11 versus wayland, I'm pretty convinced his diagnosis is correct. Namely gtk behaves differently in stetting GDK_SUPER_MASK on x11 versus wayland where on the former seeing the "Super_R" symbol will set the mask while on the latter, only the virtual modifier "Super" will set GDK_SUPER_MASK. Although it seems like in principle, one should be able to get xkb to set the "Super" virtual modifier so that GTK correctly picks it up in it's wayland code. However thus far I have been unable to make a set of xkb rules which will trigger the "Super" virtual modifier for the <RWIN> keycode despite much effort. Perhaps this is possible and I just don't understand xkb's rules sufficiently, or perhaps there is some issue in xkb which is preventing from GTK to picking up the "Super" virtual modifier. Thus far I have tried many variations on some configuration like the following default partial modifier_keys xkb_symbols "basic" { include "us(dvorak)" name[Group1] = "super"; key <RWIN> { symbols[Group1]= [ Super_R ], virtualMods= Super }; key <LWIN> { symbols[Group1]= [ Super_L ], virtualMods= Super }; }; What is also puzzling to me is that my .xkb file also includes the "misc" xkb_compatibility rules which look like the following interpret Super_R+Any { virtualModifier= Super; action = SetMods(modifiers=modMapMods); }; interpret Super_R { action = SetMods(modifiers=Super); }; ^ permalink raw reply [flat|nested] 48+ messages in thread

That's because the Wayland compositor isn't sending a keymap that makes libxkbcommon assign Mod4 to Super. See this bit of gdkkeys-wayland.c: if (mods & (1 << xkb_keymap_mod_get_index (xkb_keymap, "Super"))) state |= GDK_SUPER_MASK; which is called from deliver_key_event and keyboard_handle_modifiers in gdkdevice-wayland.c: seat->key_modifiers = gdk_keymap_get_modifier_state (keymap); and uses an XKB keymap created in _gdk_wayland_keymap_update_from_fd. It is not a bug in GTK, but a bug in the default configuration of the Wayland compositor (regardless of what their developers say.) > Although it seems like in principle, one should be able to get xkb to > set the "Super" virtual modifier so that GTK correctly picks it up in > it's wayland code.

This section of code is in gdkkeys-x11.c and called from update_keymaps: mask = 0; for (j = 0; j < keymap_x11->keysyms_per_keycode; j++) { if (syms[j] == GDK_KEY_Meta_L || syms[j] == GDK_KEY_Meta_R) mask |= GDK_META_MASK; else if (syms[j] == GDK_KEY_Hyper_L || syms[j] == GDK_KEY_Hyper_R) mask |= GDK_HYPER_MASK; else if (syms[j] == GDK_KEY_Super_L || syms[j] == GDK_KEY_Super_R) mask |= GDK_SUPER_MASK; } Which seems like it accepts the GDK_KEY_Super_L/R and subsequently sets the mask, right?

I'm not totally convinced, since sway should just be using the .xkb file I specify. The relevant code is in sway/input/keyboard.c where it uses the .xkb file in sway_keyboard_compile_keymap which then sway sets using wlr_keyboard_set_keymap inside sway_keyboard_configure. So this should be the same keymap that GTK is using. Perhaps the bug isn't in GTK but its that mutter is doing something special, but I don't immediately see how the function add_virtual_mods in src/wayland/meta-wayland-keyboard.c would cause this bug and I don't see anything else obviously related to this bug. >> Although it seems like in principle, one should be able to get >> xkb to >> set the "Super" virtual modifier so that GTK correctly picks it >> up in >> it's wayland code.

Crystal ball says you are using X Windows, and have to put remove mod4 = Hyper_L in your ~/.Xmodmap file, because GTK doesn't try as hard as regular X11 Emacs to work around the common kind of virtual modifier misconfiguration. People using X should _never_ use PGTK. The regular X build does a much better job at supporting that than PGTK ever will. It is completely pointless to put up with half-working child frames, random keyboard-related lossage, random frame placement/resizing failures, so the actual fix is to delete `--with-pgtk' from your calls to configure. Similarly, people building packages with PGTK enabled that are labeled "enhanced" are doing their users a disservice. No packager should enable PGTK by default, and every package should ideally come with a big disclaimer warning against using PGTK on window systems otherwise supported by Emacs, since time and experience shows that Emacs generally does a much better job at their support than GTK. Many people are also being mislead by articles on the internet claiming that PGTK leads to faster redisplay, such as this one: http://www.cesarolea.com/posts/emacs-native-compile That is not true, since regular Emacs with cairo uses more-or-less the same rendering path as PGTK, except when PGTK runs on Wayland, where it uses software rendering and does image compositing in software, and is thus slower than everything else. Scrolling on PGTK is also not as efficient as XCopyArea requests. But the difference in speed even on Wayland is negligible, not easy to benchmark, and not at all visible to the human eye. ^ permalink raw reply [flat|nested] 48+ messages in thread

I'd set --with-pgtk on my X11 machine ages ago, not even knowing why, and reconfiguring without that flag solved my problems with "C-;" being received as plain ";" (and some other funky key misreadings). This is why we don't copy-n-paste config! Thanks again, Eric ^ permalink raw reply [flat|nested] 48+ messages in thread

Well, I can only reiterate that on my reading the file does not clearly express the idea that PGTK should be avoided if you don't absolutely require it. And I'm someone relatively familiar with PGTK. I can easily imagine us seeing distros replacing the package emacs-gtk with emacs-pgtk on the assumption that it is a straight upgrade. It will be hard to undo that. You mentioned that various blog posts give people the wrong idea. We could decide to make the point extra clearly in INSTALL for the sake of counteracting a misconception that is continuing to spread, and is showing no signs of stopping. -- Sean Whitton ^ permalink raw reply [flat|nested] 48+ messages in thread

Reading through these sections of INSTALL, I found it very easy to assume that PGTK was a direct upgrade that would just let me "switch between running Emacs on X, Wayland and Broadway". An extremely-careful reader might then wonder why "--with-pgtk" isn't enabled by default on systems with the necessary dependencies, but that only *implies* that there are downsides to PGTK rather than stating it. I think it would be best to state explicitly that there are problems with the PGTK build, though INSTALL probably doesn't need to go into any more detail than that. In practice, a lot of people will probably just skim the documentation, so they might miss some of the more subtle points unless they're very clearly called out. ^ permalink raw reply [flat|nested] 48+ messages in thread

I think this is the main point being missed by others who have argued the existing documentation is clear enough. Like it or not, people often don't read the documentation or NEWS file carefully. There is also a tendency for people to believe any new feature is an improvement and I suspect many people will think a pure GTK build is going to be better than a hybrid X/GTK one. We should just add a very explicit and clear warning not to use --with-pgtk if your running under X and put this statement right at the beginning of the section in the NEWS file about this new option. It might even be worthwhile adding a warning in configure as well (like the one we have about pop support). Like others, I expect many distributions are going to bundle emacs-gtk believing it is an improvement. I suspect it is going to be a bigger issue given that some popular distributions, like fedora, will be shipping with wayland as their default but there will likely be many who will choose to switch back to X, but then be faced with an Emacs built with pgtk to better support the default wayland setup. ^ permalink raw reply [flat|nested] 48+ messages in thread

IME, there's nothing we can do against such misconceptions. We will get bug reports and will respond by pointing people to NEWS and INSTALL.

I didn't say they didn't read the documentation, I said they didn't read it carefully. Just like you did with my post, they skim read it and can easily miss crucial points. The fact people are building with pgtk when only running under X would tend to indicate the messaging is not adequate. Making a clear concise statement not to use pgtk when using X early, even at the start, would increase the likelihood skim readers see it. >> It might even be worthwhile adding a warning in configure as well (like >> the one we have about pop support). > > I object to annoying people who build Emacs with such warnings. > Besides, warnings (as opposed to errors) in the configure script are > easily overlooked, because people tend to leave the build run > unattended, and do other useful things while it runs. > I guess there not terribly annoying if they are easily overlooked! Just like the warning about removal of pop support and pointer to mail utils, this warning could be at the end of the build. At any rate, seems like a more important warning than one about no longer supporting pop3, which few mail providers support anymore anyway. >> Like others, I expect many distributions are going to bundle >> emacs-gtk believing it is an improvement.

All I've seen is people asking to make this more obvious and explicit. Maybe it won't make a big difference, but then again, maybe it will. The cost of making the limitations of pgtk more explicit in NEWS and INSTALL is very low and even if it only stops a few people from doing the wrorng build, reporting a 'non-bug' and getting directed back to NEW/INSTALL and having to rebuild, I think the cost has been justified. ^ permalink raw reply [flat|nested] 48+ messages in thread

If there's a significant difference, for the purposes of this discussion, between "don't read" and "don't read carefully", then I'm afraid I don't understand what you wanted to say. Either people will miss what we say or they won't. In the latter case, what we already say is enough; in the former case it doesn't matter what we will say or add to what we did already, because both INSTALL and NEWS are large files and contain a lot of stuff. So I fail to see how the fine point of "carefully" is relevant here. > > I object to annoying people who build Emacs with such warnings. > > Besides, warnings (as opposed to errors) in the configure script are > > easily overlooked, because people tend to leave the build run > > unattended, and do other useful things while it runs. > > > > I guess there not terribly annoying if they are easily overlooked! They are easily overlooked by one part of the people (usually, those who don't read the documentation "carefully" enough), and are annoying to the other part, those who don't overlook the warnings (because they usually already read the documentation and did TRT). > Just like the warning about removal of pop support and pointer > to mail utils, this warning could be at the end of the build. The warning about pop support and Mailutils is at the end of the configure script, not the end of the build. If you build by saying just "make" (which is the normal way of building Emacs these days), then you won't see the warning "at the end" because Make runs the Makefiles immediately after the configure script finishes. > At any > rate, seems like a more important warning than one about no longer > supporting pop3, which few mail providers support anymore anyway.

Appreciate the efforts on this, but the outcome seems somewhat unsatisfactory, if I understand correctly: - we have the "non-pure" gtk build which supports X (although gtk has a wayland backend, non-pure gtk assumes X) - we have "pure" gtk, which supports X and Wayland, but now it turns out there's a bunch of limitations on X. From the the time before pgtk got merged, I can't remember any wide discussion of it being wayland-only. Perhaps I misremember. I regularly use both X and Wayland, and having to have two emacsen (and remember to use the right one) just for that seems sub-optimal. Wouldn't it be better to have a single gtk3 backend? For users and developers and distributors? But maybe the problems is small, i.e. perhaps pgtk works fine on X, but doesn't currently implement a handful of things, which we can document? Then users can decide if they can live with that. Kind regards, Dirk. -- Dirk-Jan C.

I looked over those discussions not too long ago, and it seems that nobody really used the PGTK build on X Windows. Those who did immediately ran into resizing glitches, keyboard input issues, and some features just not being implemented, such as responding to configure events. > I regularly use both X and Wayland, and having to have two emacsen (and > remember to use the right one) just for that seems sub-optimal.

That list would be very long, would include serious types of misbehavior, be liable to change at the whim of the GTK developers, so the truth is that users should simply stay away from PGTK on X. ^ permalink raw reply [flat|nested] 48+ messages in thread

I believe there's something called "X-Wayland" for running X programs under Wayland, in case that's the missing piece of the puzzle?

In that case I guess one really would prefer to install both builds, if using both Wayland and X at different times. I imagine one could mostly circumvent the "remember to use the right one" issue by automatically setting PATH based on which system you were using at that time, so that "emacs" was always going to be the correct emacs. -Phil ^ permalink raw reply [flat|nested] 48+ messages in thread

Ideally, it should be possible to build a single Emacs executable that can simultaneously open frames on a tty, on an X server (some using GNUstep and others using Lucid), and on a Wayland server. It would/will require a fair bit of code changes, but AFAIK almost all of it should be "simple/repetitive": it shouldn't require any fundamental change.

If you have a HiDPI monitor, an X application on an X server gets full resolution, a Wayland application on a Wayland compositor gets full resolution, but an X application via Xwayland on a Wayland compositor gets rendered at low resolution and then upscaled. It’s a non-starter. ^ permalink raw reply [flat|nested] 48+ messages in thread

It’s a non-starter. Yup. I had a very hard time without-pgtk on a HiDPI monitor. Tried all sorts of scaling and font-sizing. Nothing worked. I am using xwayland. Because that is now default in Debian desktop environment (Gnome). So I started using PGTK build. And for my use-case, I have not faced any issues till now. It has been two months. Fonts look awesome. ^ permalink raw reply [flat|nested] 48+ messages in thread
