NVIDIA驱动故障修复求助：nvidia-smi报错、NVIDIA设置异常及VLC无法运行问题

大家好，我最近在Ubuntu系统上碰到了NVIDIA驱动相关的一系列问题，折腾了好一阵子都没搞定，特意来求助社区的大佬们！

核心问题表现 #

1. NVIDIA设置与nvidia-smi异常
   打开NVIDIA设置时会弹出错误，执行sudo nvidia-smi返回如下报错：

ERROR: Unable to load info from any available system

(nvidia-settings:7395): GLib-GObject-CRITICAL **: 19:20:22.799: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

** Message: 19:20:22.801: PRIME: Requires offloading

** Message: 19:20:22.801: PRIME: is it supported? yes

** Message: 19:20:22.837: PRIME: Usage: /usr/bin/prime-select nvidia|intel|on-demand|query

** Message: 19:20:22.837: PRIME: on-demand mode: "1"

** Message: 19:20:22.837: PRIME: is "on-demand" mode supported? yes

我在弹出的窗口里选择了「NVIDIA On-Demand」选项，但问题依然存在。不过后续直接执行nvidia-smi（不加sudo）却能正常输出显卡信息：

2. VLC媒体播放器无法正常运行
   尝试用终端打开VLC播放MKV/MP4文件时，出现报错并被强制终止，终端输出如下：

$ vlc

奇怪的是，Parole媒体播放器和ffmpeg都能正常工作。

已尝试的解决方法 #

• 卸载当前515版本驱动，重新安装nvidia-driver-460，但问题依旧没有改善。

希望各位大佬能帮忙分析下问题所在，给出修复建议，万分感谢！
