Linux Switchable에서 Intel로 변경 한 후 Ati로 다시 전환하려면 어떻게합니까?

Ati / Intel 콤보가있는 노트북이 있습니다. Debian Jessie 64에서 Amd 드라이버를 사용하고 있습니다. Ati 드라이버를 잠시 동안 사용할 수있었습니다. 그런 다음 배터리 목적으로 Ati / Amd 제어판을 사용하여 Intel 카드로 다시 전환하기로 결정했습니다. 그러나 지금은 딜레마가 있습니다. Fglrxinfo가 seg fault를 제공하고 있으며 amdccle s가 나에게 제공

amdcccle 

(process:12129): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed
Segmentation fault

나는 이제이 PC에는 더 이상 Amd 카드가 없다고 생각합니다.

aticonfig --px-dgpu
aticonfig: No supported adapters detected

Ati 드라이버로 돌아가려면 어떻게합니까? 방법을 찾을 수 없습니다. 이상적으로는 번거 로움없이 앞뒤로 전환 할 수 있기를 바랍니다. 슬프다.
