Can't switch keyboard layout on xpra 6.2.x

[V-ctor]

Can't switch keyboard layout on xpra 6.2.x by Ctrl+Space or other combinations.

Steps to reproduce the behavior:

1. xpra start :12 --start=kate
2. xpra attach ssh://name@ip/12
3. press keys for switch layout
4. no layout changes

• Server OS: Kubuntu 24.10 (X server arm64 Oracle Cloud VM)
• Client OS: Kubuntu 24.10 (Wayland)
• Xpra v6.2.1-r0 (There is no 6.2.2 for arm64)
• Xpra v6.2.2-r0 (amd64)
• No ibus on both sides

Additional info

1. xpra toolbox catches Ctrl and Space
2. Active layouts US,RU
3. The bug presents regardless of --no-keyboard-sync

[V-ctor]

I found the way to switch by console commands with preparation. But still I can't switch by keys combination.

setxkbmap -layout 'us,ru' -model pc105 -option 'grp:ctrl_space_toggle'
loadkeys ru
setxkbmap ru

So does it mean that issue with X session settings?

[totaam]

AFAICT, that's a limitation of Wayland clients.
Running xmodmap on the client is meaningless as the xpra client goes through GTK, which will use native wayland bindings.
If Wayland doesn't fire the layout-changed signal when the layout is changed, there's nothing we can do.
And even if it does, the limited keymap support from Wayland may still hinder it.

You could run the xpra client with the X11 backend to see if that helps: GDK_BACKEND=x11 xpra attach ...

[V-ctor]

GDK_BACKEND=x11 doesn't help.
Is there anything we can do? NoMachine, x2go, xRDP work quite well in terms of switching layouts.
Can we tune Wayland client? I'm not proficient in Python but I can take a look. I'd appreciate any tips.

[totaam]

You can run the client with -d keyboard and see what is detected when you switch layout, then take it from there.

[V-ctor]

I did it. And as far as I can see all keys detected properly.
By the way, I didn't say that my keys combination for server (Ctrl+Space) is not my local switching (Caps Lock). I faced such issue with NoMachine that local switching doesn't propagate to server and set up another (Ctrl+Space), acceptable trade off.
And I see by xev that server obtains both (Ctrl+Space). More over when I emulate such key press (on server) by xdotool key ctrl+cpace it does nothing as well as xte 'keydown Control_L' 'key space' 'keyup Control_L'. But at least xte switches layout in NoMachine.
So how does it work? I thought that it is enough to send keys directly to server and server processes it as it was set up. But it does not. Or client should send special event/signal of layout changing to server?

[V-ctor]

Ha I just set up rshift_tggle and it kinda works but only when I hold right shift. Looks like it behaves not as toggle but as switch but some progress.

[totaam]

I did it. And as far as I can see all keys detected properly.

It's not the keys that I expected to see. I was hoping there would be a layout-change event telling xpra to change the keymap at that point.

local switching doesn't propagate to server and set up another...

I don't see how the server would have configured x11 layout switching unless you configured that yourself manually.
Wayland clients do not have the ability to determine the exact keyboard configuration, and no idea at all about X11 layout switching configuration.

Or client should send special event/signal of layout changing to server?

With X11 clients (and depending on the exact configuration), the layout change can be detected as an X11 event, it is then forwarded to the server which then mirrors it.

[V-ctor]

I'm working on dirty hack 😀: installed sxhkdrc and made a hook for ctrl+space, hook changing locale by switching
setxkbmap -layout 'us' / setxkbmap -layout 'ru'. And it works. But before it can switch we have to set up keyboard model by setxkbmap -model pc105. And I stuck here. Nothing works. Tried xpra attach ssh://victor@X/Y --start-child="/usr/bin/setxkbmap -model pc105". Nothing in log I see

started command `/usr/bin/setxkbmap -model pc105` with pid 318529.[0m
wrote pid 318529 to '/run/user/1002/xpra/49/setxkbmap.pid'.[0m
child '/usr/bin/setxkbmap' with pid 318529 has terminated.[0m
setting keymap: layout=us,ru.

Looks like xpra override keyboard settings that were set up by setxkbmap
But if I launch konsole and execute there, then ok. I can switch layout.

[totaam]

Yes, the first thing xpra does when you connect is to setup the keyboard.
What may work is --start-after-connect.

[totaam]

A better way would be to use xpra --keyboard-options=whatever

[V-ctor]

What may work is --start-after-connect.

Is this for server ? I tried it as well, didn't work.

A better way would be to use xpra --keyboard-options=whatever

Hmmm I thought that here we can set only options like we do in for setxkbmap How would be proper to set model?
--keyboard-options="-model pc105"?

[V-ctor]

With X11 clients (and depending on the exact configuration), the layout change can be detected as an X11 event, it is then forwarded to the server which then mirrors it.

Is there a way to emulate this event?

[totaam]

How would be proper to set model?

The client can supply it:

xpra/xpra/x11/xkbhelper.py

Lines 65 to 101 in a98ab0d

	def do_set_keymap(layout: str, variant: str, options, query_struct) -> None:
	"""
	layout is the generic layout name (used on non posix platforms)
	defaults to `us`
	variant is the layout variant (optional)
	query_struct is the output of `setxkbmap -query` on the client
	parsed into a dictionary
	Use those to try to set up the correct keyboard map for the client
	so that all the keycodes sent will be mapped
	"""
	# First we try to use data from setxkbmap -query,
	# preferably as structured data:
	query_struct = typedict(query_struct)
	if query_struct:
	log("do_set_keymap using xkbmap_query struct=%s", query_struct)
	# The query_struct data will look something like this:
	# {
	# b"rules" : b"evdev",
	# b"model" : b"pc105",
	# b"layout" : b"gb",
	# b"options" : b"grp:shift_caps_toggle",
	# }
	# parse the data into a dict:
	rules = query_struct.strget("rules")
	model = query_struct.strget("model")
	layout = query_struct.strget("layout")
	variant = query_struct.strget("variant")
	options = query_struct.strget("options")
	if layout:
	log.info("setting keymap: %s",
	csv(f"{std(k)}={std(v)}" for k, v in query_struct.items()
	if k in ("rules", "model", "layout", "variant", "options") and v))
	if safe_setxkbmap(rules, model, layout, variant, options):
	return
	else:
	if safe_setxkbmap(rules, model, "", "", ""):
	return

Is there a way to emulate this event?

The system tray keyboard layout menu kinda does.

[V-ctor]

The client can supply it:

Looks interesting. I'll try to understand how it works.

The system tray keyboard layout menu kinda does.

How to get it in seamless mode?

[V-ctor]

This works:
xpra attach ssh://victor@X/Y --start-child="sh -c 'sleep 10 && setxkbmap -model pc105'"
Sorry for my laziness and probably I'm using not the best way, but I've spent a lot of time trying to get this to work and I still have some issues to work around.
So if someone else runs into this issue there is a work around it. I still believe it's worth it.

[totaam]

FWIW, with my X11 client, the server does this:

setting keymap: rules=evdev, model=pc105inet, layout=gb,gb

Connecting from a Wayland client, the keyboard detection is much more limited and shows:

setting keymap: layout=gb

As of commit 0a43ed8, I can now also change the default layout on the server:

XKB_DEFAULT_MODEL=pc105 xpra start --start=xterm

And then I get:

setting keymap: model=pc105, layout=gb

And with 89263b3, you can now also do the same from the client:

xpra attach --keyboard-model=pc105

Does that help?
Is pc105 is a more sensible default value?

[V-ctor]

Connecting from a Wayland client, the keyboard detection is much more limited and shows:
setting keymap: layout=gb

Exactly!

As of commit 0a43ed8, I can now also change the default layout on the server:

Glad to hear about any progress. Actually in KDE settings I select pc105 and it works fine but when I set keyboard model by setxkbmap it matches pc104 due Russian layout. So pc105 as default I guess is good but if it's possible to override by some extra key during CLI or/and GUI it would be great!

[totaam]

but when I set keyboard model by setxkbmap it matches pc104 due Russian layout

I don't understand - you also said that your client OS is Kubuntu 24.10 (Wayland).
Wayland doesn't use setxkbmap, which is an X11 thing.

So pc105 as default I guess is good

I am worried that this will cause regressions with the more unusual keyboard layouts, so I am going to leave it as it is for now.

but if it's possible to override by some extra key during CLI or/and GUI it would be great!

Could be done, but I don't have the time for it.

[V-ctor]

Sorry for confusing you. I have a server with Kubuntu 24.10. When I attach by NoMachine as a remote desktop it also does not recognize my client keyboard switching (Caps lock), but another combination (ctrl+space) does. Also I set keyboard as PC105 and other setting by KDE Plasma settings app and it works good. But when I connect by XPRA in seamless mode I have to use setxkbmap because KDE settings doesn't work (keyboard at least). And during setxkbmap my keyboard more matches as PC104 not PC105, I don't know why. May be it is possible to use KDE settings during XPRA session (without setxkbmap) but I don't know how.

So pc105 as default I guess is good

I am worried that this will cause regressions with the more unusual keyboard layouts, so I am going to leave it as it is for now.

Got it. Sounds reasonable.

Sounds like merge requests are welcome, right? 😉

[totaam]

Sounds like merge requests are welcome, right? 😉

Definitely, it should be relatively straightforward to add a sub-menu here:

xpra/xpra/client/gtk3/tray_menu.py

Lines 1164 to 1173 in ea92b9c

	def make_keyboardmenuitem(self) -> Gtk.Menu:
	keyboard_menu_item = self.handshake_menuitem("Keyboard", "keyboard.png")
	menu = Gtk.Menu()
	keyboard_menu_item.set_submenu(menu)
	menu.append(self.make_keyboardsyncmenuitem())
	menu.append(self.make_shortcutsmenuitem())
	menu.append(self.make_viewshortcutsmenuitem())
	menu.append(self.make_layoutsmenuitem())
	keyboard_menu_item.show_all()
	return keyboard_menu_item

And populate the list of models from a hard-coded list.

[totaam]

@V-ctor the fix in #4463 may help - and is trivial to apply by hand should you wish to do so.

[totaam]

FYI: see also #4449 (comment)

@totaam cool! It works! Thank you both @totaam and @kpushkaryov .
