我有一台 hp DL580 机器，我将 Debian 6 升级到了 7（AMD64 版；内核也更新到了 3.2）。这台机器有一块 ATI ES1000 显卡。所以我按照列出的说明http://wiki.debian.org/AtiHowTo安装了显卡，主要是安装固件-linux-非自由和libgl1-mesa-dri包。
不幸的是，3D 加速不起作用，因此 gnome-shell 以回退模式启动。输出grep AGP /boot/config-$(uname -r)是
CONFIG_AGP=y
CONFIG_AGP_AMD64=y
CONFIG_AGP_INTEL=y
CONFIG_AGP_SIS=y
CONFIG_AGP_VIA=y
输出grep DRM_RADEON /boot/config-$(uname -r)为
CONFIG_DRM_RADEON=m
CONFIG_DRM_RADEON_KMS=y
我的Xorg.0.log的内容可以看到这里。
可以看出AIGLX恢复到软件渲染。错误如下：
[2770371.141] (EE) AIGLX error: Calling driver entry point failed
[2770371.141] (EE) AIGLX: reverting to software rendering
[2770371.141] (II) AIGLX: Screen 0 is not DRI capable
我的/etc/X11/xorg.conf文件如下所示。请注意，即使没有此文件（自动检测模式），3D 加速也无法启动。

的输出LIBGL_DEBUG=verbose glxinfo >/dev/nulll如下（请注意，我使用通过 ssh 的 X11 隧道生成了输出，即ssh -X）：
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/swrast_dri.so
libGL: Can't open configuration file /root/.drirc: No such file or directory.
此外，我尝试了上述专有驱动程序，http://wiki.debian.org/ATIProprietary但没有成功。显然，AMD 放弃了对旧版显卡的支持。
我不知道该如何继续让它工作。任何帮助或提示都将不胜感激。
答案1
ATI ES1000 没有任何 3D 加速器。这就是 AIGLX 无法启动的原因。
