From the first moment, after the installation of Lubuntu 12.04, I cannot type Greek accents, when the Greek layout is selected.
The Greek layout works with some dead keys, i.e. pressing
α gives accented
α etc. In my case the dead key is ignored and
α remains without an accent.
I have looked all similar questions in askubuntu or forums, but they do not seem to provide a solution to the exact problem for Greek.
