Ustawienia monitorów

[edytuj]

Aby zmienić ustawienia ekranu musisz:
1. Wejść do menu System -> Preferencje -> Monitory
2. Ustawić własną dostępną rozdzielczość lub szybkość odświeżania.
3. Kliknąć Zastosuj

Sterowniki własnościowe

[edytuj]

Aby uzyskać dostęp do wyższych rozdzielczości, trzeba:
1. Zainstalować najnowsze sterowniki dla Twojej karty graficznej dostępne w menu System-> Administracja-> Sterowniki

2. Zezwolić na użycie oficjalnego sterownika.
3. W przypadku karty graficznej nvidia uruchom w konsoli:

sudo nvidia-settings

i wybierz preferowane ustawienia.
4. W przypadku braku dostępnej wyższej rozdzielczości (po zainstalowaniu sterowników nvidii) należy edytować
poniższy plik za pomocą edytora tekstu:

sudo gedit /etc/X11/xorg.conf

i zmienić wartości odświeżania pionowego i poziomego na wartości odpowiadające Twojej rozdzielczości, np.
dla rozmiaru monitora 1920x1200 należy wpisać w sekcji Monitor: 

 HorizSync       31.0 - 90.0
 VertRefresh     60.0

5. Następnie ponownie uruchom aplikację nvidia-settings i ustaw wymaganą rozdzielczość.
