Debian 9 DM 在 dist-upgrade 後無法載入

Debian 9 DM 在 dist-upgrade 後無法載入

我曾經使用過 Debian 8，今天我決定升級到 Debian 9。

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

我注意到此後發生了一些奇怪的事情。首先，GRUB 引導程式在某種程度上已損壞。如果我重新啟動系統，箭頭鍵根本不起作用（但是，如果我使用箭頭鍵，倒數計時就會停止），但如果我關閉系統並再次打開它，箭頭鍵就會起作用。

此外，系統現在無法引導至 GUI 登錄，而是引導至 tty。以下是啟動期間載入 tty 之前顯示的內容：

我嘗試手動運行 startx，但這不起作用並給出錯誤 1，指出，

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

我跑了

sudo apt-get install fglrx

但它說沒有安裝候選者。我怎樣才能解決這個問題？

編輯：我運行的一些命令的一些額外輸出。systemctl status lightdm.service給了：

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

 Main PID: 864 (code=exited, status=1/FAILURE)

這是輸出sudo startx：

正如我在評論中提到的，升級還將我的核心從 3.16 更改為 4.9，我發現顯示sudo startx這些核心和作業系統版本很有趣。

我的顯示卡是：

$ 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

如果我是對的，這可能會起作用：

建立這個檔案：

xorg.conf.new2

使用編輯器複製貼上，例如nano以下內容：

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

將文件保存在任意位置，例如：

/root/xorg.conf.new2

並執行：

X -config /root/xorg.conf.new2

然後：

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

並重新啟動：

sudo reboot

答案2

我有同樣的問題。

不小心從3.16升級到4.9。升級後啟動到新版本時顯示：

[FAILED] 無法啟動燈光顯示管理器

但以前的版本運行得很好。

我有一張 NVIDIA GeForce GTX 750 Ti 顯示卡。所以我高度懷疑問題跟專用顯示卡有關。

帶著這樣的懷疑，我只是從官方頁面下載了最新的 NVIDIA 驅動程序，安裝後一切正常。您可以對 AMD 驅動程式執行相同的操作。為了安裝驅動程序，我必須安裝新的標頭：

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