Olá, tenho um monitor LG L203WT, cuja, resolução nativa é 1680x1050. Eu usava Xubuntu 6.06 com essa resolução normalmente, atualizei para 6.10 e continuou normal, mas ao atualizar para 7.04 o problema surgiu. A resolução máxima que alcanço é 1280x1024. Já tentei atualizar meu driver, usar drivers antigos e várias outras formas que resolveram problemas parecidos com o meu que achei pela net.
Meu xorg.conf
