Que infeliz supresa você instalar o Ubuntu 9.10 e descobrir que a resolução padrão que ele deixa é 800 x 600. É... Tela pequena, ruim mesmo de se programar o esquema da área de trabalho. Ainda mais que os monitores que estão vindo hoje permitem resoluções da ordem de 1280x800, 1440x1024, e coisas assim.
Bom, acredito que nenhum usuário de Ubuntu esmorece. Ele simplesmente vai no xorg.conf e muda as resoluções. E, foi isso que eu fiz, fui atrás do xorg.conf... Mas, cadê o xorg.conf ??? Não tem... O Ubuntu 9.10 aboliu o xorg.conf, o que convenhamos, é contraproducente. O inittab ele já aboliu faz um tempinho, fazendo a manutenção via linha de comando bastante difícil. E agora o xorg.conf.
Mas, não se preocupem, tudo tem jeito, e, mesmo sem o xorg.conf, é possível mexer nas resoluções de vídeo do Ubuntu 9.10.
O que vamos fazer ? Coisas bem simples:
- Identificar o hardware de vídeo,
- Baixar o driver,
- Recriar o xorg.conf
- Instala-lo
Como fazer ???
- É necessário identificar qual o chipset de vídeo. Existem duas formas, a mais fácil é digitar $lspci num console de terminal. A outra seria passar uma ferramenta de Hardware Identification Tool, que vêm automática em distros de manutenção como o Ultimate Boot CD e o Parted Magic.
Se forem os vídeos da série 671/771 SiS (notebooks CCE, Intelbrás, Philco e similares, fabricados pela COMPAL de Taiwan), os drivers podem ser encontrados nestes links:
http://www.mediafire.com/?yjjnjxmyzj9
http://ncc-1701a.homelinux.net/~linux-sis/index.php?page=Downloads
- Depois de baixar o driver mais compatível com a sua placa, instale o arquivo .deb. Pode ser feito com o sudo dpkg - i "nome do arquivo" ou pelo programa Kpackagekit.
- Agora vem a parte interessante. Para ativar o funcionamento do driver, é necessário configurar o xorg.conf para usa-lo. Como o Ubuntu 9.10 não tem, vamos ter que escrever um xorg.conf e coloca-lo em /etc/X11

- Agora, no xorg.conf, altere a seguinte parte:
Section “Device”
Identifier “Configured Video Device”
Driver “vesa″
EndSection
Para:
Section “Device”
Identifier “Configured Video Device”
Driver “sis671″
EndSection
Depois, salve o xorg.conf, em /etc/X11.
Depois reinicie o seu Ubuntu e coloque na sua resolução favorita. Eu consegui as resoluções máximas, 1280x800 e 1440x1024.
Boa sorte e sucesso!!!
