nouveau 0000：01：00.0：DRM：无法空闲通道 0

我最近安装了 Linux，我注意到它有时会冻结大约 5 秒钟，然后恢复正常运行。

查看日志journalctl我发现笔记本电脑冻结时出现了这条消息：

nouveau 0000:01:00.0: DRM: failed to idle channel 0 [DRM]

我主要在使用 Chrome 时注意到了这个问题。我尝试Use hardware acceleration when available在 Chrome 中禁用它，但问题仍然存在。

现在我已经切换到 Firefox，这个问题发生的频率降低了，但仍然存在。

有人知道这个问题是什么以及如何解决它吗？

我的设置：

  • 华硕 ZenBook UM5500Q
  • Ubuntu 22.04.1
  • 窗口管理器：KDE Plasma
  • 处理器（来自lscpu）：AMD Ryzen 9 5900HX，配备 Radeon Graphics
  • 显卡（如下lspci）：GeForce RTX 3050 Ti Mobile

你应该安装专有 NVIDIA 驱动程序。开源驱动程序nouveau不支持您最近拥有的 GPU 上的所有功能，例如动态时钟恢复和 3D 支持。这是表明的在 Nouveau 的主页上。

要在 Ubuntu 22.04.1 上安装专有驱动程序，请按照以下说明操作：

确保 Ubuntu 安装是最新的：

这可确保安装内核和驱动程序包时冲突最少。

sudo apt update && sudo apt upgrade

我建议之后重新启动，然后再继续下一步：

sudo systemctl reboot

然后通过实用程序安装驱动程序ubuntu-drivers。通过以下方式调用它：

ubuntu-drivers devices

查看有关 GPU 和建议安装的驱动程序的信息。

要安装推荐的驱动程序包ubuntu-drivers，请运行：

sudo ubuntu-drivers autoinstall

完成后请务必重新启动，然后重新测试。

补充说明：

如果你需要使用 NVIDIA GPU 在 Firefox 中进行基于硬件的解码，请从以下位置构建并安装 NVIDIA VAAPI 驱动程序后端：这里。
