我有一台配备 Ati/Intel 组合的笔记本电脑。我在 Debian Jessie 64 上使用 Amd 驱动程序。我能够使用 Ati 驱动程序一段时间。然后我决定使用 Ati/Amd 控制面板切换回 Intel 卡以节省电池。但是现在我陷入了两难境地。Fglrxinfo 给我 seg 错误，amdccle 给我
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
我认为现在它认为这台电脑不再有 Amd 卡了。
aticonfig --px-dgpu
aticonfig: No supported adapters detected
我该如何返回 Ati 驱动程序？我找不到方法。理想情况下，我希望能够轻松地来回切换。这真是太可悲了。
