如何在 Debian Wheezy 和 ATI RS880 [Radeon HD 4250] 上配置 FOSS ATI 驱动程序?

安装了新的 Debian Wheezy 来享受 Gnome 3,但它以后备模式启动。我想这是因为加载的驱动程序不支持 3D 加速。

我知道相关的已安装软件包:

  • xserver-xorg-video-ati
  • libgl1-mesa-dri

Gnome 3 在 Ubuntu 12.04 上运行良好,我相信它使用的是 FOSS 驱动程序。

有趣的是,没有/etc/X11/xorg.conf,当我尝试生成它时,Xorg -configure我得到:

我现在在消息启动时发现:

答案1

您的显卡固件丢失。您必须firmware-linux-nonfree从非免费存储库显式安装。

  1. 将非自由存储库添加到/etc/apt/sources.list(或/etc/apt/sources.list.d/)

  2. apt-get update以 root 身份运行

  3. 安装firmware-linux-nonfreeapt-get install firmware-linux-nonfree

  4. 您可能必须在此步骤后重新启动或重新加载设备驱动程序。

只是一些额外的背景信息:大多数当前设备需要某种固件 blob 才能运行。 Debian 决定将这些类型的 blob 移至非自由包中(您无法更改它们,您不知道它们在做什么,有时它们甚至不可分发)。
