Eu tenho duas placas de vídeo na minha máquina como o lspci acima:

Kernel driver in use: fglrx_pci
Mas, como você pode ver, apenas a radeon 6450 está usando um driver de kernel.
Isso aconteceu depois que mudei para drivers proprietários no Ubuntu 14.04.
Funciona somente quando desabilito esse driver proprietário e carrego o driver nativo "redon" do Ubuntu. Mas o sistema fica lento nesse modo.
Existe uma maneira que eu possa carregar o driver "radeon" para o radeon 4200 e o fglrx para o radeon 6450?
Eu tentei isso em xorg.conf também:
