I'm using Ubuntu 12.04 with the XFCE desktop, all packages up to date.
I wanted to set up a keyboard layout for the Polish language (Polish uses the Roman alphabet, with a few additional characters like ą, ł, ż, etc). I went to the keyboard control panel, and under Polish I saw several options - all of them useless to me. One was for Kashubian. One was the obsolete QWERTZ layout. Several variations of DVORAK. And one for Russian - I don't even know what it was doing there. What was missing was the de-facto standard layout, known as "polski programisty" ("Polish programmer's").
Is there a package that has the layout I want?
If not, how do I create my own layout? And where do I send the patch?
