I think ibus-mozc's default is the direct input instead of Hiragana mode so you need to change the input mode to Hiragana after you select ibus-mozc from the input source indicator.

The indicator status sometimes does not match with the actual mode.

I know that. https://bugzilla.redhat.com/show_bug.cgi?id=1119967

The problem I am currently experience is that I cannot choose an input mode because there is no menu item to choose a mode from. (mozc is not activated.)

journalctl records the following suspicious error: 

: JS ERROR: Gio.IOErrorEnum: Timeout was reached

seEngine from ibusManager.js fails.

If I restart ibus-daemon (or enable mozc in emacs), then setEngine starts working.

That looks strange to me. If it works properly, you can see the input mode menu after the language selector.
How did you see that? did you install it on the fresh f35?

The image was meant to show "The problem I am currently experience [sic] is that I cannot

It worked before. And I see the menu once mozc is properly activated by restarting
ibus-daemon or by turning on mozc in emacs. 

ah.. I have just realized that merely starting emacs fixes the problem --
no need to fiddle with emacs mozc.

> How did you see that? did you install it on the fresh f35?

It's upgraded from F34. Not the fresh install. I see the same problem in other
machines recently upgraded from F34.

It turned out that any X11 app can enable mozc on my system. It is not just emacs.
Any X11 app will do. e.g. Chromium browser.

Once I starts an X11 app, the input source menu's title changes from 'あ' to 'A'
so that I can happily proceed to change its mode back to 'あ' (hiragana) from 'A' and
start typing Japanese.

;;;

While mozc is not working (e.g. before an X11 app is started), I got JS timeout
error as I previously mentioned:

: JS ERROR: Gio.IOErrorEnum: Timeout was reached
: _promisify/proto[asyncFunc]/</<@resource:///org/gnome/gjs/modules/core/overrides/Gio.js:424:45

[...]

The error is recorded every time I try to switch to mozc.

Found this article (Japanese):

"Ubuntu 21.10で日本語入力ができない問題"
https://zenn.dev/ikuya/articles/788626c3ae6ade

so, mozc needs ibus-x11?

The article has a link to ubuntu fix:

https://launchpad.net/ubuntu/+source/mozc/2.26.4220.100+dfsg-4.1ubuntu0.1

Seems SetGlobalEngine D-Bus method is succeeded.
ibus-mozc does not send ibus_engine_register_properties() with a reason.

(In reply to Takehiko Abe from comment #7)

In the Fedora 35 latest, ibus-x11 is not called in GNOME Wayland:
https://gitlab.gnome.org/GNOME/gnome-shell/-/blob/main/js/misc/ibusManager.js#L67

But ibus-x11 is not relative with the mozc issue.
ibus-mozc might need the Xwayland features.

Bad news.

Does not fix the problem. And starting X app to enable ibus-mozc no longer works
after the upgrade.

I think X app no longer works if Xwayland and ibus-x11 do not run and it's not an ibus-mozc issue.

?? Xwayland and ibus-x11 do run.

I got it. What I try to describe by "starting X app to enable ibus-mozc no longer works" is:

before the upgrade

1. mozc cannot be activated.
2. Starting emacs (or any X app) activates mozc.

after the upgrade

1. mozc cannot be activated.
2. Starting emacs (or any X app) does not activate mozc any more.

I checked the updates on WS Live again, to be sure. it works for me with the following steps:

1. Boot WS Live
2. Install ibus-mozc
3. Logout and Login to reflect it to ibus
4. Add mozc to the Input Source
5. Logout and Login to activate it
6. See the input menu

I can see the mozc specific menu at the input menu.

OK, I got the behavior now.

Now Xwayland and ibus-x11 do not run by default in Fedora 35.

But I observed Xwayland runs after users run any X apps and ibus-daemon restarts with ibus-x11.
Now Xwayland and ibus-x11 runs likes modules, interesting.

The above fix from Ubuntu is a workaround right. should this be reassigned to ibus to get the right solution for this?

Could you please explain why such a workaround is required by ibus-mozc and ibus-mozc cannot provide the right solution?

I tried the upgrade on Fedora 35 live and it worked.

I tried the upgrade again on the regular machine and it failed as it
did before. Strange. 

Not only the upgrade fails but it also prevents the 'starting X app'
work around from working. (Why? How?)

I will try the upgrade again on another machine with the freshly installed
Fedora 35 later and report back.

> I will try the upgrade again on another machine with the freshly installed

I tested the ibus-mozc in the update-testing on a freshly installed fedora 35
machine and it worked. The problem is gone. puzzling.

I will try it on yet another machine tomorrow.

a small progress.

Created a new user and confirmed that the ibus-mozc in update-testing worked there.

After I copied ~/.mozc files from a main user (me) home to the new user's home,
ibus-mozc stopped working. If removed ~/.mozc again, then ibus-mozc start working
again.

However, removing .mozc from the main user (me) account does not fix the problem.
So there's still something else.

I reverted to ibus-mozc-2.25.4190.102-7.fc35.x86_64. Then, put the xxx.desktop file
to autostart xrefresh into /etc/xdg/autostart. And that fixed the problem for me.

So, I guess, that ibus-mozc in update-testing is not working for me is a different
bug/issue that is introduced by mozc 2.26.

I figured it out. It was all my fault.

Sometime ago I learned that ibus_config.textproto could be used to set
the initial input mode to hiragana. So I tried it.

I placed it under ~/.mozc with a single line; "active_on_launch:
True". It did not work.  So I copied it under ~/.config/mozc/. It did
not work either. And I left these two files there and forgot about
them.

Now, I found that mozc 2.26 does read these files but (apparently) it
does not like the fact that they contain only one line
"active_on_launch: True" and refuses to start.

After I added "engine {}" part like:

: engines {
:   name : "mozc-jp"
:   longname : "Mozc"
:   layout : "default"
:   layout_variant : ""
:   layout_option : ""
:   rank : 80
: }
: active_on_launch: True

mozc (in updated testing) starts working.

I apologize for confusion and wasted time. The ibus-mozc update in
testing does work. and it is great that I can set the initial mode
with mozc 2.26.

Thank you.

That's good to hear. thanks for testing.
