           Summary: ibus-mozc is not loaded automatically
           Product: Fedora
           Version: 35
                OS: Linux
            Status: NEW
         Component: mozc
          Severity: medium

  Target Milestone: ---
    Classification: Fedora

Description of problem:

ibus-mozc is not loaded automatically after booting and logging in to Gnome.

Version-Release number of selected component (if applicable):

ibus-mozc-2.25.4190.102-7.fc35.x86_64

How reproducible:

Every boot and login.

Steps to Reproduce:
1. Reboot Fedora Gnome.
2. Login.
3. Select mozc from the input source selector.

Actual results:

The input source indicator is set to 'あ'. But the input source remains English.

(If ibus-kkc is present in the input source, kkc is activated instead of mozc.)

Expected results:

mozc is activated.

Additional info:

To activate mozc, I need to do either:

a). restart ibus-daemon.
b). activate emacs mozc inside emacs.

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
: ### Promise created here: ###
: setEngine@resource:///org/gnome/shell/misc/ibusManager.js:241:30
[...]

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

Found this article (Japanese):

so, mozc needs ibus-x11?

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.j...

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

Maybe a good reference for the maintaner.

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.

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

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 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.
