与 Ubuntu 21.10 相比,Ubuntu 22.04 Beta 拉来了许多软件包更新,包括一些 GNOME 42 组件,现在默认使用 GNOME 的 Wayland 会话和 NVIDIA 的驱动程序,包括 GNOME 三重缓冲补丁,用于内存外处理的 systemd-oomd 集成,让部分伙伴档案退休,调整其POWER支持基线,以及许多其他更新。
在内核方面,由于 Long Term Support (LTS) 支持状态,该版本使用 Linux 5.15。这有点不幸,因为Linux 5.17已经很稳定了,而且在5.16~5.17之间有大量的改进,其中大部分没有回传到Jammy的5.15内核构建。
如果从 Ubuntu 21.10 或者 Ubuntu 20.04 LTS 升级到 Ubuntu 22.04 LTS Beta,可以参考以下步骤:
