SUMMARY If I run ibus-daemon without uising kimpanel-ibus-panel, I can use Windows + Space shortcut to switch between input methods, but If I use kimpanel-ibus-panel, the shortcut does not work anymore, but manually clicking on the panel to change input method still works. STEPS TO REPRODUCE 1. Add a input method panel widget. 2. Run ibus with `ibus-daemon -drx -p /usr/lib/kimpanel-ibus-panel`. 3. Add more input methods to ibus. 4. Press Windows + Space to switch input methods. OBSERVED RESULT Got the space character “ ” being typed. EXPECTED RESULT Switch to another input method. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2
Can confirm this is happening under KDE wayland environment. Previous versions (5.20, 5.19) are also affected. This should be a upstream bug. Seems that ibus's keybinding mechanism for input method switch and emoji display is Xorg-exclusive (See [0]). The input method switch key should work under xwayland context. For example, the key should work under vscode. Binding keyboard switching might be possible with the input-method-unstable-v1 wayland protocol? (Not 100% sure) As the protocol allows ibus to listen to all keyboard events. The only related issue found on ibus repository is [1]. But it is marked as duplicate of implementing input method v2 protocol.

The issue happens to my X11 session, not my wayland session. So maybe the issue has nothing to do with wayland.
Ouch. Sorry for that. I don't don't have this issue under Xorg. I got rime and mozc in ibus and the Super+space thing can switch them. So, 1. Which input method (under rime) are you using? 2. Does it work in KDE 5.21?
I found out that I was actually using plasma desktop 5.21.0. The version I said before was wrong, sorry about that. And I am using ibus-libpinyin, not rime. I have tried multiple times, execute ibus-daemon -drx then Windows + Space works, but the input method panel is not being used. While executing ibus-daemon -drx -p /usr/lib/kimpanel-ibus-panel The input method panel is working, but the shortcut does not work any more.
I can't reproduce it on my system with ibus-libpinyin. Sorry can't help with this issue.
What operating system do you use? May be I am missing some packages.
I'm on arch too. Got following ibus-related packages: ibus ibus-mozc ibus-rime Following for kde: ark bluedevil discover dolphin dolphin-plugins drkonqi ffmpegthumbs filelight frameworkintegration gwenview kaccounts-integration kactivities kalarm kate kcalendarcore kcalutils kcontacts kdeclarative kde-cli-tools kdeconnect kdecoration kded kdegraphics-thumbnailers kde-gtk-config kdelibs4support kdenlive kdeplasma-addons kdesu kdewebkit kdialog keditbookmarks kfind khelpcenter kholidays kidentitymanagement kinit kio-extras kldap kmenuedit konsole kscreen ksystemlog ktorrent kwalletmanager kwayland-integration kwayland-server kwrited libappindicator-gtk3 libblockdev libkdepim libkgapi libkipi libkleo libkscreen okular oxygen phonon-qt5 pimcommon plasma-desktop plasma-meta plasma-workspace polkit-kde-agent print-manager sddm-kcm signon-kwallet-extension spectacle syndication systemsettings xdg-desktop-portal-kde
I installed all packages in your list, rebooted system, and created a new user with default settings for testing, but the shortcut still does not work.
I can't reproduce your issue under X11. I wonder if there's any other keygrab happens that prevent this from working Could you try to set another key in ibus-setup to see if it works?

Yes, I did try other shortcuts, nothing works as long as I am using kimpanel-ibus-panel.
Can you try killall kimpanel-ibus-panel and run it from command line? Did you see any error like "Could not convert keyval=.. to keycode"? If so, could you provide the output of setxkbmap -print ?

No, I did not see any error. This is the output from `setxkbmap -print`: xkb_keymap { xkb_keycodes { include "evdev+aliases(qwerty)" }; xkb_types { include "complete" }; xkb_compat { include "complete" }; xkb_symbols { include "pc+us+inet(evdev)" }; xkb_geometry { include "pc(pc104)" }; };
Is this still happening to you in Plasma 5.25 or later?
(In reply to Nate Graham from comment #13) > Is this still happening to you in Plasma 5.25 or later? Yes, it still happens with version 5.25.5.
Thank you for the follow-up!
IBus 1.5.29 better integrates with Wayland, and the Super+Space shortcut works now in Wayland apps, though not XWayland apps. https://bugzilla.redhat.com/show_bug.cgi?id=2076596
