Hello gentlemen

I am a perverted guy running sabayon (which is compiled gentoo) and ibus (anthy) for japanese input in kde/plasma.
It was working for a long time, the setup is as in this page : https://wiki.gentoo.org/wiki/IBus
Only KDE apps are is not working (ok in firefox 問題ないです).
Same account on KDE with other distro same machine works fine. GTK apps are ok, chrome as well.

I am very annoyed with that and trace the process to try to understand (interested in fix and how it works as well).
Any idea would be welcome.

I can see that with non KDE when typing (I see read/write/messages ..) that shows communication :
Code:

[pid  2339] <... write resumed> )       = 8
[pid  2339] futex(0x68b6a0, FUTEX_WAKE_PRIVATE, 1) = 1
[pid  2313] <... futex resumed> )       = 0
[pid  2313] futex(0x68b6a0, FUTEX_WAKE_PRIVATE, 1) = 0
[pid  2339] sendmsg(10, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="l\2\1\1\26\1\0\0009\3\0\0=\0\0\0\7\1s\0\24\0\0\0org.free"..., iov_len=358}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL) = 358
[pid  2313] poll([{fd=3, events=POLLIN}, {fd=8, events=POLLIN}], 2, -1) = 1 ([{fd=3, revents=POLLIN}])
[pid  2313] read(3, "\1\0\0\0\0\0\0\0", 16) = 8
..
[pid  2313] poll([{fd=3, events=POLLIN}, {fd=8, events=POLLIN}], 2, 0 <unfinished ...>
[pid  2339] poll([{fd=4, events=POLLIN}, {fd=6, events=POLLIN}, {fd=9, events=POLLIN}, {fd=10, events=POLLIN}, {fd=11, events=POLLIN}, {fd=12, events=POLLIN}, {fd=13, events=POLLIN}, {fd=14, events=POLLIN}], 8, -1 <unfinished ...>
...
[pid  2313] <... poll resumed> )        = 1 ([{fd=3, revents=POLLIN}])
[pid  2313] read(3, "\1\0\0\0\0\0\0\0", 16) = 8
[pid  2313] write(6, "\1\0\0\0\0\0\0\0", 8) = 8




but in KDE apps nothing just polling :
Code:

[pid  2338] poll([{fd=5, events=POLLIN}, {fd=7, events=POLLIN}], 2, 3997) = 0 (Timeout)
[pid  2338] poll([{fd=5, events=POLLIN}, {fd=7, events=POLLIN}], 2, 3996) = 0 (Timeout)
[pid  2338] poll([{fd=5, events=POLLIN}, {fd=7, events=POLLIN}], 2, 3995) = 0 (Timeout)


above processes :
Code:
gdbus     2313 2339     pierre  txt       REG                8,6    163992    1312949 /usr/bin/ibus-daemon

(below trace is with different pid)


So it look like KDE is not speaking to ibus for any reason.
==> Anybody has a clue on that ?

Further info :

There use to be a skimpanel stuff but I think it is deprecated.
QT looks to have integrated ibus compatibility.
ibus doesn't support ibus natively and the package app-i18n/ibus-qt-1.3.3 which present some libraries :
Code:
╠  ### /usr/lib64/libibus-qt.so
╠  ### /usr/lib64/libibus-qt.so.1
╠  ### /usr/lib64/libibus-qt.so.1.3.0
╠  ### /usr/lib64/qt4
╠  ### /usr/lib64/qt4/plugins
╠  ### /usr/lib64/qt4/plugins/inputmethods
╠  ### /usr/lib64/qt4/plugins/inputmethods/libqtim-ibus.so


Also in /etc/X11/xinit/xinput.d/ibus.conf there are some references to qt libs.
I have the qt4 one but not the following :
Code:
..
if test -f /usr/lib64/qt5/plugins/platforminputcontexts/libibusplatforminputcontextplugin.so || \
   test -f /usr/lib/qt5/plugins/platforminputcontexts/libibusplatforminputcontextplugin.so || \
..



plasma5 is compiled with ibus flag as well.

If my understanding is correct KDE/QT should load some libraries to be able to communicate with ibus.
How can I check if this libs are loaded and how kde is using them.

Thanks for any clue on that.

Here are installed packages :

Code:
app-i18n/ibus
2384 app-i18n/ibus-anthy
app-i18n/ibus-qt
app-i18n/ibus-qt-1.3.3


.xprofile
Code:
export LC_CTYPE=ja_JP.UTF-8

export GTK_IM_MODULE=ibus
export XMODIFIERS=@im=ibus
export QT_IM_MODULE=ibus
#export QT_IM_MODULE=ibus kwrite
ibus-daemon -d -x

My apologies if replying to such an old thread is the wrong thing to do.

I got ibus working with KDE/Qt apps by setting the environment variables in a /etc/plasma/startup/99-ibus.sh:

Code:
export XMODIFIERS="@im=ibus"
export GTK_IM_MODULE="ibus"
export QT_IM_MODULE="ibus"


I also no longer use an .xinitrc or .xsession with KDE, I'm not sure if that affects it.

Why it is wrong to answer old threads?

I put those export(s) into .bashrc

Is it the same?

If the answer is valid, it's probably fine. However, waking up an old thread to post a highly speculative answer or to ask the original poster for more information is more questionable.

In my humble (and limited to my case) opinion ibus is just crap.
Let me wreak!

I was struggling with iBus for several times and I've lost the battle. In the end got rid of this messy tool.
BUT! If you find a solution to make it do what it should have, I'll gladly thank you and install it back :)
