I'm running Kubuntu with KDE as my main desktop environment.
A while ago I set up dead keys so I can type Chinese pinyin and other accented letters and special characters.
As a side note, I use IBUS because it seemed to be easiest to set up my Chinese character IMEs with.
Until the update, dead/compose keys worked fine in all applications.
Now, they work in QT applications, but not GTK ones (such as this browser). This is unfortunate, as it's where I do most of my typing. My workaround right now is to type accents into KDE's launcher and copy past (Alt+F2, type using dead keys, Ctrl+X, Esc, Ctrl+V), which is kind of a hassle.
I'm not sure what information is useful in debugging this, as it's been a while since I set this all up.
Interestingly, the environment variable $QT_IM_MODULE has no value. $GTK_IM_MODULE has xim.
I have ibus-gtk3 installed, I can post whatever information else would be helpful in diagnosing.
I have pasted below the setup script that is in various places (ex. en_US, /etc/X11/xinit/xinput.d/ibus, etc.). I'm not sure which one takes priority, and I'm not sure any are being run, as QT_IM_MODULE has no value when I echo it, whereas these all indicate it should be "xim" by default if not ibus.
I should mention also that the libraries (im-ibus.so, etc) mentioned below I do not have, nor can I find how to get them or where they are to link them. In fact, my gtk-3.0.0/ and qt4/ directories do not even have an inputmethod/ or plugin/ directory. This may be part of the problem, but again, it was working before the update, so I don't know.
