我有一台运行 64 位 OpenSuse 12.3 的联想 ThinkPad S531。
此款笔记本电脑配备以下显卡：
- 集成英特尔高清 4000。
- 独立（无多路复用）AMD Radeon HD 8670M
标准设置后，根据 hwinfo 似乎使用 i915 驱动程序用于集成显卡。
Gnome 系统信息显示“llvmpipe 上的 Gallium 0.4 (LLVM 0x302)”作为图形驱动程序。
问题是，虽然 gnome 3 启动正常，但是所有的 3D 效果都由 CPU 呈现，因此 CPU 负载非常高（浏览时约为 60-70%）。
我尝试安装专有的 fglrx 驱动程序，但是我没有 3D 加速，因此启动了 gnome 3 的后备模式。
我读到过，要使 fglrx 驱动程序正常工作，您不应将“nomodeset”放入内核启动选项中，但这样一来，我只会看到空白/黑屏……
我需要一个解决方案，要么使用具有适当 3D 加速的集成显卡（不是 CPU），要么使用可以正常工作的 ATI 卡，否则我的电池寿命将少于 2 小时，尽管它应该超过 8 小时……
这似乎与操作系统无关，因为我尝试在 Debian 7 上进行同样的操作，但没有成功。

答案1
我通过使用较新的（3.11）内核解决了这个问题
首先，我在 OpenSuse 12.3 上安装了最新的 xf86-video-intel，但这并没有改变任何东西。然而，当我添加 Tumbleweed 存储库并更新所有软件包时，问题就解决了。我可以nomodeset从启动选项中删除，3D 加速完美运行！
我在这台 ThinkPad 上安装了 Arch，它运行得很好，可能比 Tumbleweed 更稳定……
Linux 3.11.2-1-ARCH #1 SMP PREEMPT Fri Sep 27 07:35:36 CEST 2013 x86_64 GNU/Linux
现在我的电池续航时间大约为 6 小时……太棒了！
