一个月都无法解决这个问题。
我随机做某事，更改选项卡或执行简单的任务时，我的屏幕崩溃，无法移动光标，然后显示器关闭（变黑 2 秒），然后恢复正常但冻结，我必须重新启动笔记本电脑。

尝试重新安装 Ubuntu，尝试“WaylandEnable”，安装 GPU 的自定义驱动程序，但没有任何效果。
如何解决这个问题？
答案1
最近，当我的内核从 5.15.0-60-generic 升级到 5.19.0-32 generic 时，我也遇到了这个问题。降级回 5.15 版本修复了您遇到的完全相同的冻结问题。我相信，如果您查看系统日志，您会在系统冻结时看到 VM_L2_PROTECTION_FAULT_STATUS。环顾四周，我看到一些帖子说 5.19.19（相信是这个版本）应该有 gpu 修复程序，但我使用的 32 版本仍然遇到了这个问题。希望这能有所帮助！
