Hi Scot: Thanks for quick reply. For example: when I press accent + e, a normal e without accent shows up. My keyboard map settings are set to "Es" at the top right corner on the Ubuntu 12.04 Unity taskbar. About PPA, regrettably I have no access from here. Only repositories for Ubuntu LTS from my work. Meantime I'm thinking about to use the Windows version of Lyx. Hopefully when Ubuntu 14.04 finally released I will have access to the latest versión of Lyx from its repositories right? Thanks! José.
