Hur ökar man skärmupplösningen?

Hej!

Inställningsfönstret för skärmupplösning i Ubuntu 7.04 visar endast valmöjligheterna 640x480 och 800x600 med grafikkortet Matrox G400 Millennium AGP installerat (som borde klara bättre upplösningar). 

Vet någon vad det kan bero på, och om det finns något enkelt sätt att öka skärmupplösningen? Skulle behöva minst 1280x1024.


Grafikkort: Matrox G400 AGP 32MB
Skärm: 21 tums CRT
Operativsystem: Ubuntu 7.04

Hej.
Hoppas det går bra att jag skriver i den här tråden.

Jag kan inte ha höger upplösning än 1024x768

SV: Hur ökar man skärmupplösningen?

Postat: 12 jun 2007, 11:51

Även jag har problem med att fixa högre upplösning än 1024x768. Jag behöver 1280x800 på min toshiba satellite m70-144 med grafikkortet ati radeon mobility x700. I xorg har jag försökt lägga till 1280x800 + ändrat depth till 16. Detta fungerade inte. Jag har också testat 1280x1024 vilket inte heller fungerade. Min xorg.conf:

Uppdatering: Jag lyckades fixa upplösningen genom att lägga till 1280x800 men lät depth vara kvar på 24. Nu ser ubuntu fantastiskt bra ut!

;D

Det räckte inte med att lägga till "1280x1024" i filen xorg.conf, men följande ändring löste problemet:

Först tog jag reda på specifikationerna för min monitor (Nokia Multigraph 445M), och antecknade frekvensvärdena för 'Horizontal Sync' och 'Vertical Refresh'.

Därefter skrev jag i Terminalen: sudo gedit /etc/X11/xorg.conf

Under "Section 'Monitor'" lade jag till två rader: en för HorizSync, följt av dess frekvensvärden, och en för VertRefresh följt av dess värden.

Under "Section 'Screen'" lade jag till upplösningen "1280x1024"

Sparade xorg.conf, och loggade ut och in igen. 


Här är länken till en text som beskriver olika sätt att lösa skärmupplösningsproblem:

dvs så här:

...

Namnet som följer efter Section Monitor Identifier ska vara samma som namnet som följer efter Section Screen Monitor. I mitt fall "Generic Monitor".
