пару не удается запуститься из-за недостающих библиотек на 32 бита

на новой установке пара на kubuntu 14.04, получающем это

Running Steam on ubuntu 14.04 64-bit
STEAM_RUNTIME is disabled by the user
Error: You are missing the following 32-bit libraries, and Steam may not run:
libXtst.so.6
libXrandr.so.2
libgtk-x11-2.0.so.0
libgdk_pixbuf-2.0.so.0

Править: после выяснения, как установить корректные библиотеки на 32 бита, пару все еще не удается запуститься. я думаю, что вещью cef-расширений является отвлекающий маневр.
