Ubuntu Studio 22.04 LTS（KDE）登录屏幕间歇性挂起

我刚刚在 Dell Precision 7530 笔记本电脑上安装了 Ubuntu Studio 22.04。我遇到了一个麻烦的问题：

登录屏幕偶尔会挂起 - 我可能可以输入一个字符，但随后它就变得没有响应了。光标仍然在移动。我必须按 ctrl + alt + F3 并重新启动显示管理器才能进入。当我运行 systemctl status 时，它告诉我它已降级，并且 --failed 标志显示[电子邮件保护]有问题。

一旦我重新启动显示管理器，错误就会消失，我就可以进入。

BIOS 已更新，安全启动已禁用，传统模式 ROM 已禁用。我已为我的显卡安装了最新的（已测试）nvidia 驱动程序版本 535.146.02。冻结问题之前存在，之后也存在。我的显示管理器是 SDDM。

我努力了。

  1. rm .Xauthority。这对某些人来说是一个解决方案，但对我没有影响。
  2. 确保 /etc 具有正确的权限，事实确实如此。
  3. 在 BIOS 中禁用 Thunderbolt 自动切换。没有明显变化。
  4. 在 BIOS 中禁用可切换显卡，这看起来好像我缺少任何合适的显卡驱动程序。已恢复该更改。
  5. 在桌面会话（系统设置）下，我选择从空会话开始，而不是恢复之前保存的会话。这对关机速度有一些积极的影响，但问题仍然存在。
  6. 在启动和关闭 --> 登录屏幕下，我选择了 Breeze，因为它对某些人有帮助。重启后我看到的第一件事就是冻结的登录屏幕。:)

以下是失败服务的示例：

一旦我登录，一切都正常。睡眠和空闲也没有问题。

我被难住了。我该怎么做才能解决这些问题？
