kwin_wayland CPU 超高

arterxu · 2024-07-22 10:22:25

最近更新版本之后，电脑巨卡无比，发现什么都没有开的情况下kwin_wayland这个进程占用cpu就非常高

搜索一些资料像是kde的一个bug,没有找到办法临时修复

sudo perf top 看看能不能看到它在干什么。

得装 -debug 包啦。不过这儿有个 JIT 字样，不知道能不能看到些啥。总之你先按回车看看是在哪个库文件里，然后装对应的 -debug 包。腾讯云有 -debug 包的镜像。

arterxu · 2024-07-22 19:40:28

不会debug，看不出要debug哪个包？我对比另外一台电脑更新内容，看里面有linux-firmware-20240703.e94a2a3b-1，盲猜是驱动更新有问题了，downgrade linux-firmware执行到上一个版本20240610.9c10a208-1没有问题了。

最近一段时间感觉笔记本比较烫，打开 Zotero 或 firefox 后，kwin_wayland 的 CPU 占用在 7%-16% 间跳动，并且 zotero-bin 或 firefox 进程也保持相似的 CPU 占用率。
将 linux-firmware 降级无法解决。

目前尚不清楚原因。你说有影响吧，电脑整天很烫。你说没有影响吧，它又占着 10% 左右的CPU。无奈。
