Meu ubuntu estava trabalhando normalmente com 2 monitores porém um dia liguei ele e o segundo monitor não reconheceu mais. Ele está em dual boot com o windows e está funcionando. Este problema já ocorreu antes e eu reinstalei o ubuntu para corrigí-lo.
Minha placa de video é offboard GeForce GT 740.
Há mais alguem com um problema semelhante ?
