Debian 9 DM 在 dist-upgrade 后无法加载

Debian 9 DM 在 dist-upgrade 后无法加载

我曾经使用过 Debian 8，今天我决定升级到 Debian 9。我通过运行以下命令来升级：

sed 's/jessie/stretch/g' /etc/apt/sources.list
sudo apt-get update && sudo apt-get upgrade
sudo apt-get dist-upgrade

我注意到此后发生了一些奇怪的事情。首先，GRUB 引导加载程序在某种程度上已损坏。如果我重新启动系统，箭头键根本不起作用（但是，如果我使用箭头键，倒计时就会停止），但如果我关闭系统并再次打开它，箭头键就会起作用。

此外，系统现在无法引导至 GUI 登录，而是引导至 tty。以下是启动期间加载 tty 之前显示的内容：

我尝试手动运行 startx，但这不起作用并给出错误 1，指出，

Failed to load module fglrx (Module does not exist 0)

我跑了

sudo apt-get install fglrx

但它说没有安装候选者。我怎样才能解决这个问题？

编辑：我运行的一些命令的一些额外输出。systemctl status lightdm.service给了：

lightdm.service - Light Display Manager
   Loaded: loaded (/lib/systemd/system/lightdm.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Thu 2017-07-06 19:17:26 IST; 2min 18s ago

这是输出sudo startx：

正如我在评论中提到的，升级还将我的内核从 3.16 更改为 4.9，我发现显示sudo startx这些内核和操作系统版本很有趣。

我的显卡是：

$ lspci -vnn | grep VGA – Vlastimil 16 hours ago
00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Mullins [Radeon R4/R5 Graphics] [1002:9851] (rev 45) (prog-if 00 [VGA controller])

答案1

如果我是对的，这可能会起作用：

创建这个文件：

xorg.conf.new2

使用编辑器复制粘贴，例如nano以下内容：

Section "ServerLayout"
    Identifier     "X.org Configured"
    Screen      0  "Screen0" 0 0
    InputDevice    "Mouse0" "CorePointer"
    InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "Files"
    ModulePath   "/usr/lib/xorg/modules"
    FontPath     "/usr/share/fonts/X11/misc"
    FontPath     "/usr/share/fonts/X11/cyrillic"
    FontPath     "/usr/share/fonts/X11/100dpi/:unscaled"
    FontPath     "/usr/share/fonts/X11/75dpi/:unscaled"
    FontPath     "/usr/share/fonts/X11/Type1"
    FontPath     "/usr/share/fonts/X11/100dpi"
    FontPath     "/usr/share/fonts/X11/75dpi"
    FontPath     "built-ins"
EndSection

Section "Module"
    Load  "glx"
EndSection

Section "InputDevice"
    Identifier  "Keyboard0"
    Driver      "kbd"
EndSection

Section "InputDevice"
    Identifier  "Mouse0"
    Driver      "mouse"
    Option      "Protocol" "auto"
    Option      "Device" "/dev/input/mice"
    Option      "ZAxisMapping" "4 5 6 7"
EndSection

Section "Monitor"
    Identifier   "Monitor0"
    VendorName   "Monitor Vendor"
    ModelName    "Monitor Model"
EndSection

Section "Device"
    Identifier  "Card0"
    Driver      "amdgpu"
    BusID       "PCI:0:1:0"
EndSection


Section "Screen"
    Identifier "Screen0"
    Device     "Card0"
    Monitor    "Monitor0"
    SubSection "Display"
        Viewport   0 0
        Depth     1
    EndSubSection
    SubSection "Display"
        Viewport   0 0
        Depth     4
    EndSubSection
    SubSection "Display"
        Viewport   0 0
        Depth     8
    EndSubSection
    SubSection "Display"
        Viewport   0 0
        Depth     15
    EndSubSection
    SubSection "Display"
        Viewport   0 0
        Depth     16
    EndSubSection
    SubSection "Display"
        Viewport   0 0
        Depth     24
    EndSubSection
EndSection

将文件保存在任意位置，例如：

/root/xorg.conf.new2

并执行：

X -config /root/xorg.conf.new2

然后：

sudo cp /root/xorg.conf.new2 /etc/X11/xorg.conf

并重新启动：

sudo reboot

答案2

我有同样的问题。

不小心从3.16升级到4.9。升级后启动到新版本时显示：

[FAILED] 无法启动灯光显示管理器

但以前的版本运行得很好。

我有一块 NVIDIA GeForce GTX 750 Ti 显卡。所以我高度怀疑问题与专用显卡有关。

带着这样的怀疑，我只是从官方页面下载了最新的 NVIDIA 驱动程序，安装后一切正常。您可以对 AMD 驱动程序执行相同的操作。为了安装驱动程序，我必须安装新的标头：

apt-get install linux-headers-$(uname -r)
