Placa Radeon HD 6850, driver radeon xorg
Tenho placa Radeon HD 6850 com dois monitores DVI. O comando X -configure gerou o arquivo xorg.conf com o qual vejo o desktop espelhado em ambos os monitores. Se eu for para System- > Preferences- > Monitors e reinicializá-lo Mesma imagem em todos os monitores , a área de trabalho será estendida nos dois monitores.
Isso é quase o que eu quero, mas ainda há um problema. Se eu maximizar uma janela, ela se espalha nos dois monitores e fica feia. Como posso alterá-lo?
Eu tinha ideia de que, se eu alterasse um pouco as configurações do xorg e fizesse com que houvesse duas seções 'Screen' (por monitor), o GDM pensaria que havia duas telas diferentes e criaria dois desktops diferentes. Mas o xorg parece ignorar minhas configurações (embora o arquivo de log mostre que não há erro e minha configuração é aceita). Xrandr também diz que há apenas uma tela.

BTW, na verdade eu tenho duas placas de vídeo e três monitores. Mas o problema diz respeito apenas ao adaptador Radeon.
