I have a french keyboard with Greek localisation in KDE 4.10.5 and Mageia 3 64bit
Since many years i am not able to type accents for French letters in KDE/qt applications .
In Firefox and Libreoffice i am able to type accents without any problem
In Greek i can type accents without any problem
i installed the ibus-qt4 without succes, it did nt change anything in my problem
Exemple:
I can type the accents like:
^e ^u ^o

The same for the ¨ i type ¨ and after the letter but nothing happens (no output), i press a second time the letter and i see only the letter without the accent
In Libreoffice it works

http://userbase.kde.org/ComposeKey#Curr ... figuration

afaik the only deadkeys supported by XOrg would be grave, acute and circumflex - LO/OOo may have it's own key composition scheme based upon the used language, but since Ä would be composed by "+A, i assume this sucks as you'd to type '" A' to get '"A'?

No, i don't take any result when i type « ¨ + A »

I fear we're talking past each other.
To turn a key sequence into another (eg. diacretic) character, one requires a "compose key" - which does no longer exist on modern keyboards.
A reasonable approach is it to map it to the otherwise useless caps/lock key - by adding "compose:caps" to XkbOptions - i'm not aware of a key to generate the dicretic "¨" and the only xkb options i know in this regard are "deadgrave", "deadacute", "deadcircumflex".

I don't know about ibus behavior, but would suggest to just try "kwrite --noxim"
If that helps you, you can "export QT_NO_IM=1" in a ~/.kde/env scriptlet

I tried from a new user and it works.
So it is a setting of my user
The "kwrite --noxim" did n't work
any idea where can be hidden this setting ?

kcmshell4 keyboard or qtconfig[-qt4], for the latter the default input method or xim style (Interface tab)
but that's just a very wild guess w/o an idea what's broken (since i apparently compose keys differently

I launched the qtconfig, and in the tab interface, in the section 'Default input method' i chose 'ibus'
Now i can type accents normally!

I have a message in the terminal when launching qtconfig but i don't see any problem:

QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: No such file or directory
QFileSystemWatcher: failed to add paths: /home/dglent/.config/ibus/bus
Bus::open: Can not get ibus-daemon's address.
IBusInputContext::createInputContext: no connection to ibus-daemon


Thanks
