Ubuntu 18.04 работает с низкой графикой после добавления nomodeset в grub

Несколько дней назад я попытался установить Ubuntu 18.04 на свой ноутбук. Но процесс установки зависает в начальной фразе. Поэтому кто-то предлагает мне добавить nomodeset в grub. После добавления номодет в grub. Ubuntu успешно установлен. но после входа в систему я вижу, что рабочий стол Ubuntu работает с низкой графикой. Некоторые послы говорят, что мне пришлось установить драйверы NVIDIA (поскольку у notebok есть карта NVIDIA Geforce 520M). Я следовал их инструкциям, но это вылетает ОС.
