Hello, I'm having some trouble with fcitx5.
I read some topics here, and reddit, arch wiki etc.
But I didn't find solution.
So I decided to post this topic..
( Sorry for bad English )
When I run 'fcitx5-configtool', i get the following error:
Full Log:
fcitx5-config: QDBusError("org.freedesktop.DBus.Error.NoReply", "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.")
I also noticed that 'fcitx5-remote' doesn't work either.
When I run it, it shows:
"Failed to get reply."
It seems like fcitx5 and DBus can’t communicate with each other, but I’m not sure how to fix it..
Can you tell me how to solve this problem or how to find the actual reason of this problem?
Thanks for reading.

It seems to be a bug in Fcitx5 when running under Hyprland. I updated Fcitx5 to version 5.1.15 today and encountered the same error. After downgrading to 5.1.14, everything works fine again.
Offline
it worked! thank you for help!!

I encountered the same error, That should report an issue to Hyprland maintainers? This update having breaking my workflow. I surprised found that fcitx5 version fixed some problem in niri, but Damaged hyprland input method completely.
Offline
Yes, the new version has issues. After installation, all input methods disappeared.
