Mam mały kłopot z HDMI na laptopie Lenovo B570 z Ubuntu 12.04.
Próbowałem sam, lecz jako początkujący mam trochę ograniczoną wiedzę ;(
Instalacja jest nowa.
Chce kupic nowy TV, na ktorym poprzez HDMI bede mógł oglądać filmy i korzystac z sieci - jako monitor.
Zabrałem laptopa do sklepu aby spr. jak to wygląda i ... zobaczyłem czarny ekran oraz "brak sygnału" na TV:(
Sprzedawca powiedział ze TV nie widzi laptopa.
Zatem szukałem ustawień grafiki i HDMI.
W karcie System, szczegóły grafiki mam
Sterownik: Intel® Sandybridge Mobile x86/MMX/SSE2
Laptop posiada karte grafiki: Intel HD Graphics 3000
