eu tenho problemas durante a inicialização com o módulo radeon. tela preta aparece. Se eu adicionar "blacklist radeon" ao blacklist.conf eu posso inicializar normalmente. mas eu preciso de vgaswitcheroo que não esteja disponível sem módulo radeon.

Eu tive o mesmo problema. O sistema não inicializaria com o radeon carregado. Eu fiz isso:
adicione blacklist radeon ao final de /etc/modprobe.d/blacklist.conf
adicione essas linhas antes de ' exit 0 ' em /etc/rc.local
modprobe radeon
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
Lembre-se de fazer o executável rc.local.
Agora o módulo radeon será recarregado, vgaswitcheroo será reativado e a placa ATI será desativada. Refrigerador, mais silencioso
Você pode inicializar com o módulo radeon na lista negra e, em seguida, carregá-lo em rc.local (modprobe radeon). Isso fez meu sistema inicializar estável.
oh, como pode ver, você não precisa do cartão radeon, certo? você está feliz com a GPU integrada? se assim for, simplesmente delete (com synaptics) drivers xorg para radeon (nomes de pacotes são como xorg-driver-ati e xorg-driver-radeon ou algo similar) o problema é que esses drivers de alguma forma não funcionam corretamente com o kernel padrão do Ubuntu 11.04
eu fiz isso. O cartão intel funciona como costumava fazer. vga_switcheroo está no lugar. está tudo bem mas você não pode usar o cartão radeon, claro.
verifique se esta postagem pode ajudar:
