我已经在我的笔记本电脑 MSI GP70-2PE（GP702PE-426XUA）上安装了全新的 kubuntu 22.04，并且在驱动程序管理器中我安装了 418（专有），并且在操作系统重新启动后我看到的内容：https://prnt.sc/_XdxizS0yXGS
但是运行 nvidia-settings 时我在控制台中看到一些错误：
(nvidia-settings:2079): GLib-GObject-CRITICAL **: 06:45:14.541: g_object_unref: assertion 'G_IS_OBJECT (object)' failed
** (nvidia-settings:2079): CRITICAL **: 06:45:14.543: ctk_powermode_new: assertion '(ctrl_target != NULL) && (ctrl_target->h != NULL)' failed
ERROR: nvidia-settings could not find the registry key file or the X server is not accessible. This file
should have been installed along with this driver at
/usr/share/nvidia/nvidia-application-profiles-key-documentation. The application profiles will
continue to work, but values cannot be prepopulated or validated, and will not be listed in the help
text. Please see the README for possible values and descriptions.
** (nvidia-settings:2079): WARNING **: 06:45:14.591: PRIME: Failed to execute child process “/usr/bin/prime-supported” (No such file or directory)
** Message: 06:45:14.591: PRIME: is it supported? no
并且打开的 nvidia-settings 看起来不正确： https://prnt.sc/O1tCaE3NnYzJ
什么配置错误？我该如何修复它？

我之前在笔记本电脑上使用过 kubuntu 20.04，没有遇到这样的问题……
