最近我的 Ubuntu 系統（19.04）遇到了一些問題。我認為這與內核5.0.0處理圖形介面的方式有關。
我的電腦是華碩 ZenBook 13（幾個月前買的），我的 GPU 是整合的（英特爾高清顯示卡，「Whiskey Lake」）。
主要問題是我經常需要（重新）啟動 20 或 30 次才能正確啟動系統。大多數時候，它只是在 GRUB 選單之後卡在紫色螢幕上，並且風扇以最大速度運行 - 停止電腦的唯一方法是按住電源按鈕。這似乎是完全隨機的。我強烈懷疑圖形設定有問題。當 Ubuntu 正確啟動時，我可以毫無問題地使用它——一切似乎都反應得很好。
我嘗試完全重新安裝 Ubuntu，但問題仍然存在。由於某種原因，情況變得更糟：現在，即使是 Live USB 驅動器也無法正確加載（即使在安全圖形模式下，我在選擇選項 [嘗試 Ubuntu / 安裝 Ubuntu] 後也只是出現黑屏）。我可能搞亂了 xserver，但我不知道如何以乾淨的方式重新安裝它。
我嘗試了在其他線程中找到的許多不同的潛在解決方案，包括nomodeset在 GRUB 命令中插入和各種其他命令（acpi=off...），但無濟於事。有時，nomodeset允許我訪問控制台模式 - 但是，正如我所說，它似乎是完全隨機的。

我無法更改 BIOS 選單中的任何選項，除了已停用的安全模式和快速啟動模式。
我根本不是專家。我很樂意提供您可能問我的所有日子。
隨機啟動成功的原因可能是什麼？
