Boot
啟動時帶有滑鼠指針的黑屏，KDE Neon
前言：
我有一台聯想 Z50，4GB 記憶體。我嘗試在其上安裝KDE Neon 5.15.4（基於 Ubuntu 18.04），但我遇到了問題。我是菜鳥，所以問題可能過於描述了。
問題：
我第一次安裝時，安裝很完美（我選擇安裝額外的附加功能），我選擇了“嘗試作業系統一段時間”而不是“立即重新啟動”選項。
但是當我啟動到已安裝的作業系統時，在初始啟動螢幕之後，它拋出對話框說
ksplashqmlcrashed 和 2 或 3 個以上（我意外地關閉了它們，因為ksplashqml’ 框需要一些時間才能關閉），所以我不知道還有什麼崩潰。在那之後，我留下了一個帶有指針的黑屏。我等了很長時間，然後按了很長時間的電源按鈕（強制關機）。我重新啟動，但指針出現相同的黑屏，這次沒有對話框。再次，我強行關閉電源。
我試過的：
- 有人說安裝時不要安裝任何額外的東西，所以通過擦除整個磁碟重新安裝 KDE Neon。
安裝後，我選擇了“
reboot now”選項並啟動了作業系統，儘管在啟動螢幕後載入桌面需要相當長的時間。然後，一切正常，我使用和更新（到KDE 5.16.4），使用 安裝 NVIDIA 驅動程序（在我的情況下為 340），然後重新啟動。我再次用指針迎接黑屏，沒有對話框。pkcon refresh``pkcon update``sudo ubuntu-drivers autoinstall2. 然後我開始了解Ctrl++Alt-F1。F6我去了tty2，登錄但什麼也做不了。然後我發現了關於
startx。因此，在登錄tty2後，我輸入startx並按輸入鍵，然後我收到了ksplashqml崩潰的對話，但這次載入了桌面。我已從對話框中附加了日誌。此外，
rendering with software is enabled當我以這種方式到達桌面時，它會顯示。一段時間後桌面變得靜止且無法操作（關閉視窗通常會觸發它），如果我啟動發現然後關閉它（即使在啟動後也是如此）。有時甚至
ksmserver-logout-greeter崩潰（附有日誌）。有時解析度較低。 3. 引導至 grub（使用Esc）並替換ro quiet splash為nomodeset quiet spalsh或僅nomodeset在 grub 中（通過按下e進行編輯）。 4. 禁用模糊效果。 5. 更改核心版本（5、4.18、4.15.18）。 6. 將nouveau驅動程序列入黑名單（我現在已將其列入白名單，不知道如何檢查，方法是刪除行blacklist nouveau並options nouveau modeset=0從我按照本指南/etc/modprobe.d/blacklist-nvidia-nouveau.conf添加的文件中刪除）。我還有什麼選擇嗎？我可以從 Konsole ( tty2 ) 執行終端命令。

解決了！
在嘗試了 KDE Neon 之後，我切換到了 Pop！作業系統並拋出由於電腦的安全策略而無法啟動的消息。我在 BIOS 中啟用了安全啟動。一開始我看不到 Secure Boot 的選項，不得不在 BIOS 中將 Boot Mode 設置為 UEFI。安全啟動似乎阻止了一些圖形驅動程序，但我很驚訝作業系統是如何啟動的！
另一個問題可能是 NVIDIA Optimus（可切換或混合顯卡），在這種情況下這可能很有用。
順便說一句，我現在在 Kubuntu 上。:)
希望能幫助到你！
