Are the wlr components you listed thing that we'd need to add to the pywlroots bindings? Or something that we would be doing something with in qtile?

Probably best added to pywlroots.

The virtual keyboard manager would probably need a class for each of struct wlr_virtual_keyboard_manager_v1 and struct wlr_virtual_keyboard_v1, but they themselves are pretty small.

The screencopy and gamma_control ones are more simple, they'll just need functionality to call wlr_screencopy_manager_v1_create and wlr_gamma_control_manager_v1_create, and don't even need any objects or return values as eveything is then internal to wlroots. I think wlr_xdg_output_manager_v1_create is the same, but IIRC that may get deprecated in favour of wlr_output_manager_v1_create, which will also need an object with events.

wlr_layer_shell_v1_create will also need an object + events, and a struct wlr_layer_surface_v1 class most likely.

Pretty nice Wayland protocol explorer: https://wayland.app/protocols/

That is nice. All of the xml protocols are also scraped and included in the pywayland RTD page: https://pywayland.readthedocs.io/en/latest/module/protocol/wayland.html but the formatting and discoverability isn't quite as nice as that page.

About window decoration protocols, there is xdg-decoration used by some applications, and server-decoration which, although used by GTK, is becoming obselete in favour of xdg-decoration. There is a submission to GTK to migrate: https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/2191

server-decoration is being removed in a future version of wlroots: https://github.com/swaywm/wlroots/blob/master/include/wlr/types/wlr_server_decoration.h#L1-L4

I've submitted implementations for xdg-decoration to pywlroots and Qtile, but I figure we can get away with not implementing server-decoration at all. Until GTK updates, windows that use it will default to using client-side decorations and draw their own title bars etc, around which our window borders are drawn.

Firefox also seems to use GTK to draw a title bar.

I think this is actually good to have in the interim, as it's been 10 months since that GTK merge request, and with little activity who knows what timescale it could be that this gets updated.

About clipboards/selection, I'm not sure what the situation is with them, so help is wanted if anyone wants to play around with some wayland stuff :)

Currently, without any explicit setting up of any selection/clipboard related managers, I can select text from gnome-terminal and paste it back into gnome-terminal with a middle click. I can also select, Ctrl-C, Ctrl-V to copy-paste within Firefox. However I can't paste between these clients. Some parts of the primary-selection protocol appear to be implemented in wlroots' seat so perhaps nothing further needs doing at all. https://github.com/swaywm/wlroots/blob/master/types/seat/wlr_seat.c

Looks like some clients use different protocols for this. When selecting text in kitty, I get this error:

[143 13:27:57.279026] [glfw error 65544]: Wayland: Cannot copy no primary selection device available

So I guess something that is needed is not yet implemented.

m-col May 31, 2021
Maintainer Author

I added a handler for the primary selection protocol which has nicely extended the number of clients that can copy and paste between each other.

I don't see anything about restarting qtile in the todo list. As I just experienced a crash (Runtime Error : Failed to create wlroots backend), I am not sure if I should already report it.
Additional question : is it already possible to change keyboard layout?

4 replies

m-col Jun 1, 2021

Restarting doesn't really make sense when using the Wayland backend. As an X WM, the connection to the X server lets clients stay alive in the absence of the WM, which can start up again and continue its role as if nothing happened, but in Wayland Qtile is the server connected to the clients, so when it exits the clients disconnect, and most will exit themselves. There is no away around this, so when somebody updates Qtile they must close their windows, exit the compositor, then start it up again.

The other reason people restart is to reload their configs. I started working on a way to reload the config without restarting in #2369 before getting carried away with the Wayland stuff. I'm now running under Wayland full-time so this does get annoying quite often, so I want to continue that work soon but I'm still busy with refactoring the tests so I can test the new backend. As for the Runtime error... I should probably just disable restarting when using this backend.

Additional question : is it already possible to change keyboard layout?

I'm not actually sure, it isn't something I've thought about because I only use one layout! Please could you post an issue about it? This way we can keep track of it. Sway seems to handle it which might be a good place to start: https://github.com/swaywm/sway/blob/7c74f01f0ae9d5b3f92d3e6fc64cb9abe95b4c52/sway/commands/input/xkb_switch_layout.c

Fabien-Bernard Jun 1, 2021

I am so used to hit the restart key after a change in my config file, I will add a backend condition for this key in my config to avoid launching it by inadvertence. Thank you really much for the explanation - and for all the good work on this!

I exported the XKB_DEFAULT_LAYOUT variable before launching qtile to solve my keyboard headache. I'll continue to explore the xkbcommon library before creating an issue.

Yeah, just sneaking in to emphasize the "thank you", because this is a tremendous work that you've been doing by both implementing Wayland support and the first non-X Qtile core, which could open the door for some really fun stuff. Thanks a million!

Huh, cool. Do you get the correct context menu behaviour when running cage directly?

jjsullivan5196 Aug 29, 2021

@m-col Just tried it, yeah it works with cage by itself, maybe a protocol bug? Everything seems to be OK in firefox, so can't really say for sure.

Looks like its generally an issue with any popup-style menus, the main menu doesn't work either when nested. I might hammer on this a little harder since I want to be able to test software in chrome :^)

This is actually really useful. I'm using it for discord, which seems to be working 100% perfectly as if it was just natively running within Qtile. Awesome idea. Chromium has always played against the rules with it comes to X so it's possible the problems lie just with that unfortunately.

goduck777 Dec 29, 2021

Hi. My workflow relies on using SSH X11 forwarding, which works well in other wayland compositor but not in Qtile. I wonder if there is a workaround for this, as I don't want to launch my terminal in cage.

m-col Jan 15, 2022

@goduck777 for that we would need XWayland support. We do not currently implement this I'm afraid, but an implementation would be welcome if a contributor is interested.

I think I have something that could be added to the To Do List if i didn't miss it. As I understand it Wayland compositors are the one handling things like dpi/scaling. Could not find a setting or config option for this but maybe i just missed it or have misunderstood something.

Another feature that would be nice: input inhibitor for screenlockers like waylock and swaylock. I think that's the job of the compositor to implement? For example when I try to run swaylock I get this:

To correct myself, not so much "like they could" - you need to use lazy.reload_config rather than lazy.restart.

You need to configure scaling for your output using a tool such as kanshi, wlr-randr or wdisplays.

What are your opinions on wlr_scene @m-col? AFAICT it would be a good fit for qtile, it still has some rough edges such as not implementing scissors though. Most compositors are moving towards this such as sway (has a WIP Pr). This would give us full damage tracking for free. Additionally it would simplify the codebase a lot

I haven't looked into it for a while, but from what I understand, Qtile is exactly the kind of compositor that would benefit from it, and I'm all for it. I suspect it would also make it much more easy to get atomic state changes WRT rendering which would be amazing. Are you interested in working on it? 😉

Xwayland in Gnome supports more resolutions.

In gnome I use the monitor at 4k scaled at 200% and in Qtile using wlr-randr.

If I write to a console in Gnome the xrandr command, it gives me the following output

XWAYLAND0 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 620mm x 340mm

   640x400       59.95  
   320x200       58.96

   720x400       59.55  
   640x350       59.77

and if I write it to Qtile, only this

XWAYLAND0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 620mm x 340mm
   1920x1080     59.96*+

This makes steam games in qtile the maximum resolution is 1920x1080, while in gnome games can use resolutions up to 4k (my monitor is 4k), could something be done so that this can be implemented in qtile? Thank you

Definitely! That's pretty interesting, I didn't notice (but can reproduce) that XWayland isn't aware of all modes available by the outputs. I've generated an issue from this post: #3847

Sorry I don't know what bug should I call this (or maybe it was my setup problem):

Davinci Resolve workspace wont open after the project chooser menu,
Wine apps such as LoL game client only appear part of it inside a small float window that un-resizable,
Also often time the login or search promt in browser (chromium base and mozilla) will cause the browser window to freeze, can't close the window too. The search box in qtile docs is one example. I think is some javascript problem, never happen with normal text box.

Are these all running with XWayland? There are a number of problems with that at the minute unfortunately. For firefox you can make it use wayland with MOZ_ENABLE_WAYLAND=1 if you aren't using that already. It may fix the issue for that.

You might be interested in this sway thread: swaywm/sway#1486. Tldr: it is technically possible but not something that is supported by sway or wlroots (yet). It looks like someone got it working a bit with XWayland clients specifically (if I understood correctly) though that doesn't really help you.

The naive screen locking protocol we were using previously is no longer supported by libraries like swaylock, which now implement the much more secure ext-session-lock-v1 protocol. So I think the "screen locking" box should be unchecked--my fix from 3 years ago is no longer sufficient today (#2852). I may look into getting a new PR out if I have time.

Edit: This is already in wlroots, so just the implementation is needed!

Just an update from my side, I am rewriting the wayland backend in c, and have most things working. I will also implement new protocols such as ext-session-lock-v1. The reason being is that it's too hard to follow upstream pywlroots with bindings

Implementing text-input-v3 and input-method-v2 wayland protocols would allow IME multilingual input to work on wayland. Currently only non IME languages like english, spanish, mongolian work on wayland. Languages like Japanese, Chinese are untypable on wayland natively unless its xwayland, GTK or QT programs.

Once the C rewrite is done, I'll try to implement it myself but I would have to figure out how to place and edit text on qtile's wayland backend.
