我最近购买了一台联想 g505s，其规格可以找到这里。
设置完 Ubuntu 13.04 后，我尝试安装 ATI 专有驱动程序。但只检测到我的集成显卡。此外，屏幕右下角有一个 AMD 不支持的硬件水印（只要系统正常运行，这不是问题）。
甚至 lspci -v 命令也无法检测到我的专用显卡。我尝试检查我的 BIOS，但找不到任何在集成显卡和专用显卡之间切换的选项。目前，BIOS 下的显卡选项设置为可切换显卡。
请帮助我启用我的专用显卡。以下是 lspci -v 的输出：-

答案1
我之前通过以下方式解决了这个问题。
1）升级到最新的内核和头文件： http://kernel.ubuntu.com/~kernel-ppa/mainline/linux-3.8.yz-review/2013-09-21-raring/
2）获取最新的 ATI 专有驱动程序： http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx
3）然后执行 sudo apt-get update && sudo apt-get upgrade，问题解决。:)
