Ubuntu не может распознать Видеокарту после установки его вместе с Windows

Следующее является этими двумя драйверами в моей системе:

Я не уверен, является ли моим основным драйвером Intel один или Nvidia один?

Я запускаю Ubuntu как двойную загрузку alog с Windows 10, который имеет Nvidia как драйвер по умолчанию.

Я хотел подтвердить это перед хождением дальше с установкой CUDA.
