Okay, the solution suggested in this gitlab issue comment fixes it for me: https://gitlab.gnome.org/GNOME/gnome- shell/-/issues/4511#note_1309852
The solution is to skip gnome-tweaks altogether and instead set a custom shortcut using gsettings: $ gsettings set org.gnome.desktop.wm.keybindings switch-input-source "['<Shift>Alt_L']" $ gsettings set org.gnome.desktop.wm.keybindings switch-input-source-backward "['<Alt>Shift_L']" Caveat: if you have more than two layouts, this works a bit weird: Alt+Shift does cycle between the layouts normally but Shift+Alt just cycles between the last two, so be careful with how you press it. I tried variations of these commands where I switch the shortcuts around or use the same one or leave one out but couldn't find anything that doesn't behave weirdly; perhaps I haven't tried hard enough though. ** Bug watch added: gitlab.gnome.org/GNOME/gnome-shell/-/issues #4511 https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/4511 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1956916 Title: Using certain xkb-options, e.g. Alt+Shift, for switching input sources not reflected by the input source indicator in a wayland session To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1956916/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
