Acabei de mudar do driver ATI de código aberto para o catalisador porque tive muitas falhas na minha caixa do Linux ao reproduzir vídeos em flash.
Parece que com o fglrx meu sistema é mais estável, mas perdi meu terceiro monitor e não posso ativá-lo mais.
Eu tenho cartão de cedro:
[ 723.679] (**) fglrx(0): AMD 2D Acceleration Architecture enabled

Não consigo ativar a exibição de CRT2 com xrandr:
[zork@serenity ~]$ xrandr --output CRT2 --auto
xrandr: Configure crtc 2 failed
O Catalyst Control Center relata a exibição do CRT como desativado e não há opção para ativá-lo.

Tentei definir "Disable" para "false" em 0-CRT2 e adicionar PreferredMode, Position e TargetRefresh, mas isso não ajudou. O Catalyst Control Center quando executado como root sobrescreve essas alterações e desativa o CRT2.
Estou usando o xorg 1.14 e o catalisador 14.4 no Arch Linux.
