Если я правильно понимаю то на видеокарту Intel  не загружен драйвер.Как это можно сделать?

Вообще то, если вы знаете имя драйвера, это делается командой modprobe (можно и insmod).
Но это если драйвер (бинарный, .ko) присутствует у вас в каталоге modules. Если вы его там не найдёте, то вам, возможно придётся его собрать из исходников (скачав эти исходники), это несложно.
