lspci, не обнаруживающий мою видеокарту

Я недавно купил Lenovo g505s, спецификации которой могут быть найдены здесь.

После установки Ubuntu 13.04 я пытался установить ATI собственные драйверы. Но только моя интегрированная графика обнаруживается. Плюс существует AMD неподдерживаемый аппаратный водяной знак в правом нижнем углу моего экрана (не проблема пока системные работы).

Даже lspci-v команда не обнаруживает мою выделенную видеокарту. Я пытался проверить свой BIOS, но я не могу найти опцию переключиться между интегрированной и выделенной графикой. В настоящее время графическая опция под BIOS установлена на переключаемую графику.

Помогите мне включить свою выделенную видеокарту. Вот вывод lspci-v:-
