是否有支持将 Dell XPS-13 9370 从 LTS 18.04 升级到 20.04 的方法？当然，我希望我的所有设备驱动程序和已安装的应用程序不会因此而损坏。
答案1
这发行说明说
您可以从 Ubuntu 18.04 LTS 或 Ubuntu 19.10 升级到 Ubuntu 20.04 LTS。
仅供参考。Xubuntu 20.04 在我的 Dell XPS-13 9365 上的安装（不是升级）非常完美。为了安全起见，我决定将之前的 Ubuntu 和原始 Windows 保留在分区 4、5 中，并将 20.04 安装到分区 6 中。

开箱即用，支持 XPS 13 硬件。除指纹识别外，其他功能均正常（支持的，但我在 Xfce 中没有找到任何 GUI）。内核 5.4 很棒。平均核心温度下降了 10-20 度！我的 19.10 Xubuntu 桌面平均运行在 60-70 C。现在核心温度在空闲时低于 40 摄氏度，在 30% CPU 使用率时为 50 摄氏度（Cooler Master pad；20 C 室温）。图形（Intel 615）在 3 个外接显示器上运行更快、更流畅DisplayLink。
答案2
我有一台安装了 18.04 的 XPS-13 9370，意外安装了 19，然后被建议升级到 20.04，现在这台笔记本电脑上运行起来似乎还算顺利。
有人能解释一下如何添加戴尔固件更新吗？
