我有时在关机时会出现此错误，屏幕会充满以下行：
AsimSafwan kernel: [ 2086.606655] nouveau 0000:01:00.0: fifo: SCHED_ERROR 20 []
电脑无法关机，而是运行上述错误的脚本，我不得不强制关闭电脑。
kernlog 和 Syslog 都已满，并出现相同的错误。我最近删除了 Kernlog1(8gb) 和 Syslog1(5gb)。在此之前，我使用的是 16.04，没有这样的问题。安装 18.04 后，我开始遇到这个问题。我第一次安装 18.04 时，几天后我的根空间 (50 gb) 就因为日志而满了，我在格式化根分区后重新安装了 Ubuntu 18.04，但问题仍然存在。

答案1
问题出nouveau在你系统使用的驱动程序上。请注意日志中的字符串： Kernel driver in use: nouveau。
首先删除所有 Nvidia 驱动程序：
sudo apt purge nvidia-*
然后安装推荐的 Nvidia 驱动程序：
sudo apt install nvidia-driver-390
重新启动计算机：
sudo reboot
最后关注本指南将 nouveau 驱动程序列入黑名单。
