Can't switch between groups and input methods in steam chat.

[Steamvoker]

I'm on KDE using fcitx 5.1.5. Tried both X11 and Wayland. With and without environment variables (QT/GTK/SDL_IM_MODULE). While checking the issues I thought this is #442, but I'm not using modifier-only shortcuts; Ctrl + Space for IME and Meta + Space for group switching. Is that issue still not fixed or am I missing something?

@Steamvoker input method never works in steam ValveSoftware/steam-for-linux#3255

[Steamvoker]

Does that mean that switching groups also doesn't work because of that? Thank you for the answer!

[wengxt]

Switch group on X11 should always work. It's based on xcb key grab if there's no focused application.

Switch group on wayland you'll need to use this kcm in systemsettings. There's no other similar mechanism available under wayland to implement what I want.

[Steamvoker]

Currently in KDE X11 session with these environment variables set:

XMODIFIERS=@im=fcitx
QT_IM_MODULE=fcitx
GTK_IM_MODULE=fcitx
SDL_IM_MODULE=fcitx

And the group enumaration set to Super+Space, it just puts one space in the chat instead of switching.
By the way I can't switch groups at all when there's no active window. Do I need to have libxcb and/or libxcb-util installed?

@Steamvoker can you post the output of fcitx5-diagnose? so we know the version and what’s being installed on the system.

[Steamvoker]

fcitx5-diagnose.txt

[wengxt]

@Steamvoker Can you run "fcitx5 -r --verbose=xcb=5" and paste the output here?

So I can see

D2023-12-07 09:59:51.631594 xcbconnection.cpp:279] Grab key for X11 display: :0
D2023-12-07 09:59:51.631624 xcbconnection.cpp:254] grab keycode 65 modifiers 65
D2023-12-07 09:59:51.631719 xcbconnection.cpp:254] grab keycode 65 modifiers 64

This means it try to grab Super + space and Super + Shift + Space to initiate group switching

Does it produce any log when you try to press Super space?

I'd expect to see something like:

I doesn't do anything when steam chat is active or when there are no active windows.
And this shows up when I press Super+Space in Discord:

@wengxt pinging in case you missed my response.

Since I can't properly switch between layout groups, I have decided to disable Allow Overriding System XKB Setting in XCB addon settings and just use fcitx5 for input method only. With this I set my layouts in KDE's settings and trigger input method in fcitx. This fixed my issue of not being able to switch layouts in Steam (although IME still doesn't work there, but I assume that's an issue on their end) and when there is no input field in focus. While not an ideal solution, it works. Hope this helps someone.

I'm also having this issue:

1. I can only switch between layout groups when focusing a text input element.
2. I can't switch between layout groups when there's no active window, or no text input element is focused on.
3. On Steam, I can't switch between layout groups even when focusing a text input element. In fact, I also cannot paste the clipboard's contents.

I've tried everything that's been suggested in this thread.
