And some other info may help:

这是以下的配置xorg.conf：

console# cat /etc/X11/xorg.conf

答案1

您实际上在控制台上使用 vesa fb 吗？如果是这样，请检查 /dev/fb 上的权限（目前，在典型情况下是指向 /dev/fb0 的符号链接） - 您可能需要 chmod 666 链接指向的设备节点。

如果您实际上没有使用 Framebuffer/vesa 控制台，请编辑 xorg.conf 以使用 Radeon 驱动程序（我相信在 fglrx 包中称为“radeon”）。但是，您可能必须从 ATI/AMD 的网站下载此软件包 -

SC。
