最近我的 Ubuntu 系统 (19.04) 出现了一些问题。我认为这与内核 5.0.0 处理图形界面的方式有关。
我的电脑是华硕 ZenBook 13（几个月前购买的），我的 GPU 是集成的（英特尔高清显卡，“Whiskey Lake”）。
主要问题是，为了正常启动系统，我经常需要（重新）启动 20 或 30 次。大多数情况下，系统只是卡在 GRUB 菜单后的紫色屏幕上，风扇以最大速度运转 — 停止计算机的唯一方法是按住电源按钮。这似乎是完全随机的。我强烈怀疑是图形设置问题。当 Ubuntu 正确启动时，我可以毫无问题地使用它— 一切似乎都反应良好。
我尝试完全重新安装 Ubuntu，但问题仍然存在。出于某种原因，情况变得更糟：现在，甚至 Live USB 驱动器也无法正确加载（在选择选项 [尝试 Ubuntu/安装 Ubuntu] 后，即使在安全图形模式下，我也只看到黑屏）。我可能弄乱了 xserver，但我不知道如何以干净的方式重新安装它。
我尝试了在其他线程中找到的许多不同的潜在解决方案，包括nomodeset在 GRUB 命令中插入和各种其他命令（acpi=off...），但无济于事。有时，nomodeset允许我访问控制台模式 — 但正如我所说，它似乎完全是随机的。

我无法更改 BIOS 菜单中的任何选项，安全模式和快速启动模式除外，因为它们已被禁用。
我根本不是专家。我很乐意提供您可能要求的所有日志。
这次随机启动成功的原因可能是什么？
