Я использую ноутбук Dell Vostro 3750 с 2 мониторами. ОС Kubuntu 13.04
1 монитор, который я подключил с VGA и он хорошо работает. Но другой монитор, подключенный к порту HDMI, не обнаруживается. Я подключил монитор HDMI к своим друзьям ноутбук, имеющий Windows 7, и он хорошо работает. но только с Ubuntu это не работает.
