Ubuntu 18.04 systemd-udevd 使用高 CPU，与 nvidia 显卡冲突 [重复]

  • 772

就像在Ubuntu 18.04 systemd-udevd 使用高 CPU，与 wifi 冲突一样，我也遇到了 systemd-udevd 的 CPU 使用增加的问题，这只能通过 (sudo) 杀死特定进程来临时解决。但是，我的问题不在于 wifi，而在于 NVIDIA 显卡：

阅读udevadm monitor给出了重复的行，例如：

KERNEL[408.860342] remove   /module/nvidia (module)
KERNEL[408.901437] add      /module/nvidia (module)
KERNEL[408.916478] remove   /module/nvidia (module)
UDEV  [408.944573] add      /module/nvidia (module)
UDEV  [408.969459] remove   /module/nvidia (module)
KERNEL[409.039276] add      /module/nvidia (module)
KERNEL[409.060769] remove   /module/nvidia (module)

并检查less /var/log/syslog给出的重复版本：

驱动程序是最新的，笔记本电脑上的所有其他软件都已（今天）升级到最新版本，所以我不确定是什么导致了这个问题。我的图形没有任何问题（除了由于这个过程导致 CPU 使用率变高时出现延迟），所以我很茫然。

我怎样才能停止这种重复，从而吞噬 CPU？

nvidia cpu-load systemd 18.04

  1. Best Answer

    我通过运行解决了这个问题

    sudo mv /lib/udev/rules.d/71-nvidia.rules ~

    并重新启动，以便 udev 不会尝试加载 nvidia 模块。

    到目前为止，一切都很好，尽管我怀疑这可能对图形做了一些我不知道的事情。

  2. 解决方法

    启动后不久，运行以下命令：

    sudo systemctl stop systemd-udevd systemd-udevd-kernel.socket systemd-udevd-control.socket

    sudo systemctl start systemd-udevd systemd-udevd-kernel.socket systemd-udevd-control.socket

    它在我的戴尔笔记本电脑上工作，所有问题都消失了。

  3. 我几乎遇到了确切的问题。这终于为我解决了：

    sudo apt-get remove nvidia*
sudo apt-get install --reinstall nvidia-driver-390

    编辑：重新启动后问题又回来了。我还没有解决方案
