本质是因为intel核显的可变刷新率特性问题在Intel graphics的wiki页面中有描述[点击跳转查看](https://wiki.archlinux.org/title/intel_graphics#Screen_flickering)
解决办法是在内核参数中禁用此特性,方法如下:
1. grub启动页面增加临时解决重启失效
按e编辑启动参数`kernel`开头的那一行最后增加`i915.enable_psr=0`
2. 编辑`/etc/default/grub`文件(永久解决)
`GRUB_CMDLINE_LINUX_DEFAULT`开头的行最后增加`i915.enable_psr=0`
