我的图形驱动程序不见了

Question

我在 Xubuntu 13.10 64 位。这个问题会告诉您有关我的图形卡的所有信息。

昨天我遇到了一个问题，我的显卡驱动失败了，现在如果我登录到 xubuntu 默认桌面，我看到的只是黑屏但是我可以登录到 xfce 会话

的输出inxi -G：

/var/log/Xorg.0.log.old和/etc/X11/xorg.conf。请注意，我不再有 xorg.conf，因为我遵循了下面的答案，但是即使我生成了新文件，它也会看起来像上面的文件，我试过了。

Answer 1

您xorg.conf有两个设备部分：

Section "Device"
    Identifier  "aticonfig-Device[0]-0"
    Driver      "fglrx"
    BusID       "PCI:1:0:0"
EndSection

Section "Device"
    Identifier  "intel"
    Driver      "intel"
    Option      "AccelMethod" "uxa"
EndSection

这会导致您的计算机尝试加载fglrx和intel驱动程序。虽然实际上可以在 Linux 上使用多个显卡，但我怀疑您是否可以使用集成（intel）和专用（ATI）显卡来做到这一点。删除该部分很可能intel会使一切恢复正常（假设fglrx驱动程序在您的系统上工作，但据我了解它过去是这样，所以它可能会）。因此，注释掉该intel部分并仅保留fglrx：

Section "Device"
    Identifier  "aticonfig-Device[0]-0"
    Driver      "fglrx"
    BusID       "PCI:1:0:0"
EndSection

#Section "Device"
#    Identifier  "intel"
#    Driver      "intel"
#    Option      "AccelMethod" "uxa"
#EndSection

然后重新启动 X，假设没有其他问题，一切都应该没问题。

如果没有，您可以尝试xorg.conf使用 ATI 的配置工具创建一个新的aticonfig：

sudo aticonfig --initial

如果您确实走这条路，我还建议您仔细阅读该程序的选项，它们非常广泛：

aticonfig --help | less

最后，有关 ATI/AMD 卡的Arch wiki 页面是此类信息的重要来源。

Answer 2

尝试清除 GC 驱动程序并重新安装：

sudo apt-get purge fglrx fglrx-pxpress

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install fglrx fglrx-pxpress

如果这不能解决问题，那么就需要编辑 XConfigs 了！
