在前12年的学生生涯中我们都在期待着这一次的暑假以为在这个没有作业的假期里我们就可以充分的享受人间的美好。可是当时我们不知道这人间的烦恼可不止作业这一种无论是突如其来的疫情导致开学延期还是等待录取时的不安。
虽说在暑假时,拥有了自己的笔记本电脑,可是在高中三年屯下的游戏还是没有玩几个,看来我也是“喜加一”的受害者。虽然在高考后入坑了原神,但是假期间我并没有太过投入的玩。
暑假下定决心要好好的学一学可是看着我gitee上暑假期间那稀疏的提交我就知道我又摸了一个暑假的鱼。

算起来,我已经和`Wayland`显示协议相爱相杀了整整一年了,从`KDE plasma X`到`Hyprland`,再尝试小众的`labwc`,最后回到了`KDE plasma X`。而在2024年2月29日`KDE plasma`释出6.0版本,将`Wayland`作为默认的显示协议,我也在第一时间更新了版本并使用`wayland`显示协议。现在,我可以比较确定的说,`Wayland`目前已经达到可用的水平了,而且我还是使用`RTX 3060`显卡。

不过`XWayland`应用程序在使用`NVIDIA`驱动时会存在一个神奇的**同步失败**问题,表现为在`xwayland`中部分控件闪烁,交替显示更新前和更新后的帧,而且这个问题几乎不能被截屏抓到,具体可以见`freedesktop`上的这个[issue](https://gitlab.freedesktop.org/xorg/xserver/-/issues/1317)。虽然这个议题下面有着很长的讨论,还是建议大家完整的看一遍,里面甚至还有:

省流:这个议题讨论了在`xserver`中提供显式同步的协议原语,方便图形驱动程序知道什么时候渲染的帧发生了变化。因此这并不是一个`NVIDIA`驱动程序的问题,而是需要将`Linux`显示协议栈从隐式同步迁移到显式同步。但是相关的工作还在开发过程中,因此解决方法有两个:
