lspci не обнаружил мою графическую карту

Недавно я приобрел Lenovo g505s, технические характеристики которого можно найти здесь.

После настройки Ubuntu 13.04 я попытался установить проприетарные драйверы ATI. Но только моя встроенная графика обнаруживается. Кроме того, в правом нижнем углу моего экрана есть аппаратный водяной знак неподдерживаемого AMD (это не проблема, если система работает).

Даже команда lspci -v не обнаруживает мою выделенную графическую карту. Я попытался проверить свой BIOS, но я не могу найти никакой опции для переключения между встроенной и выделенной графикой. В настоящее время графическая опция в BIOS настроена на переключаемую графику.

Пожалуйста, помогите мне включить мою специальную графическую карту. Вот вывод команды lspci -v:-
