![Ubuntu Budgie 19.10 速度大幅下降](https://linux22.com/image/1169167/Ubuntu%20Budgie%2019.10%20%E9%80%9F%E5%BA%A6%E5%A4%A7%E5%B9%85%E4%B8%8B%E9%99%8D.png)
笔记本电脑:华硕 Sonic Master E4003S,4 GB RAM
问题:升级到 Ubuntu Budgie 19.10 后,速度大幅下降。机器需要 310 秒(= 5 分 10 秒)才能响应任何点击或击键。光标冻结;键盘无响应。检查日志以获取见解。
内核日志错误:
perf: interrupt took too long (10512 > 9967), lowering kernel.perf_event_max_sample_rate to 19000
