Current Problems
问题是：
The Dynamic Switch needs Xorg support for the discrete videocard assigned for rendering to work [1]. So, rendering on the discrete gpu will not work until the Xorg team adds support for it.
动态开关需要 Xorg 的支持。
This means that with a muxless intel+ati design, you cannot use your discrete card by simply modprobing the radeon module.
不能简单使用 modprobing 来加载 radeon 模块。
As of now, there are 3 choices:
有 3 种选择。
-
Disable the discrete card and use only the intel igpu. This is not needed for kernels version >= 3.12 with radeon DPM enabled; the open source graphics driver manages the card automatically. For kernels older than 3.12, see the solution below.
禁用 A 卡，只用 I 卡，内核版本在 3.12 以上的，系统会自动实现。 -
Test and improve some virtualGL based program to make the switch, like the common-amd branch of bumblebee project. Check the project repository and this useful post.

Use the proprietary driver with powerxpress (a.k.a. pxp) support maintained by Vi0l0 (remember to check for xorg compatibility).
安装官方的专有驱动 PowerXpress 来管理。
