我在 Ubuntu 22.04 主机和客户机上使用 virtualbox 6.1.34，gnome-shell 每隔一分钟就会崩溃。它多年来一直运行良好，但我不知道到底发生了什么变化。
我将虚拟机复制到了另一台具有相同虚拟机的电脑上，并且它运行良好。
作为用户，我看到的情况是，我关注的窗口突然被切换，并且短时间内我看不到顶部栏。
也许这与显卡驱动程序有关。有办法确认吗？我尝试了几种专有 NVIDIA 驱动程序和通用驱动程序，结果相同。
我可以在日志中看到，但我无法理解的内容（请参阅下面的完整消息）：
- 无法更新舞台视图演员……
- 查找权限时出错：... 没有地理位置条目 3.ATK Bridge 已禁用，但 a11y 已启用。
- 取消设置 XDG_SESSION_ID，getCurrentSessionProxy() 在用户会话之外调用。直接询问 logind。
- 无法创建文件 /run/user/1000/gnome-shell-disable-extensions:... 文件存在
1 - 我经常遇到这种情况，但不知道它是什么意思。
2 - 我不在乎地理位置，或者？我可以禁用导致此错误的应用程序以确保它不相关吗？
3/4 - 这到底是什么意思？有关系吗？
5 – 该文件不存在，所以我不知道为什么它会抱怨它存在，而且我不知道它是否相关。
这是其中的一部分journalctl /usr/bin/gnome-shell：

编辑：修复了一些不相关的错误并更新了日志，以便更简单地查看实际问题。
答案1
这个错误显然是由 5.15.0-47 内核中的一些更新引起的。这里有一个错误报告：https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1988473
据报道，切换到较早的内核（例如 5.15.0-46）可使 Virtualbox 客户机再次正常运行。此外，该错误已在更高版本的 Virtualbox 中得到修复，例如 6.1.36。
从上面的帖子中：
我将 virtualbox 上传到 focal (20.04) 和 jammy (22.04) 的未批准队列中。等待 SRU 团队查看
因此看来修复正在进行中。
据报道，它可以影响任何 VirtualBox 客户机，包括 Windows、不同的 GNU/Linux 发行版。

从上面的帖子中：
它与修复安全漏洞的内核提交 6e8ec2552c7d 相关。
我猜想最新的 Linux 内核通过重新设计的随机数生成器获得了更大的安全性增强。该改进的详细描述如下： https://www.theregister.com/2022/03/21/new_linux_kernel_has_improved/。
这一改进似乎非常重要，因此它已被移植回仍然广泛使用的旧内核。
VirtualBox 测试版本 6.1.35r151864（及更新版本）应该支持主机和客户机上的 Linux 内核 5.18、5.17.12+、5.15.44+、5.10.119+ 等。
