System76 驱动程序导致 Nvidia 显示器撕裂

  • 772
Laptop: Sytem76 Bonobo 15, 2024
PopOS 22.04
NVIDIA GeForce RTX 4080
x11 (not Wayland)

打开笔记本电脑包装后，我将在 Dell XPS 9710 笔记本电脑上运行 PopOS 22.04 的 NVMe 棒插入其中。尽管外部显示器不可用，但它立即启动，因此我认为它使用的是内置/英特尔 GPU。运行apt驱动程序更新后，Nvidia GPU 可用，但存在严重的图形撕裂问题，显示器最活跃的部分会不断跳跃和刷新。我与 System76 进行了通话，它向我提供了以下建议：

看起来问题在于您安装了适用于 Ubuntu 的 Nvidia 驱动程序，并尝试使用 Prime 进行设置。尽管您正确地认为这是一台通常使用 Prime 的 Optimus 笔记本电脑，但我们发现使用我们的包装会带来更好的体验。

# add the system76 PPA
sudo apt-add-repository -y ppa:system76-dev/stable
sudo apt update
# remove the current Nvidia packages
sudo apt purge ~nnvidia
# make sure we are getting the most recent release
sudo apt update
# make sure apt and dpkg were not interrupted
sudo dpkg --configure -a  
sudo apt install -f  
# remove supporting libraries as well
sudo apt autoremove --purge
# install the nvidia driver
sudo apt install system76-driver-nvidia
# reboot the system to start using the new driver
sudo reboot

我确实遵循了这些步骤，但问题仍然存在，即使用 Nvidia 显卡时出现屏幕撕裂，如果图形活动较低，则在混合模式下会保持稳定，并且内部显卡不会出现此类问题。

这是以下的输出nvidia-smi：

需要注意的是，在nvidia-settingsNvidia显卡上运行时，会出现以下错误：

** (nvidia-settings:92652): WARNING **: 21:23:21.908: PRIME: Failed to execute child process “/usr/bin/prime-supported” (No such file or directory)

nvidia-settings这是寻找 PRIME 的输出：在此输入图像描述

我不确定为什么prime-supported丢失，但是当我尝试安装它时，它报告以下内容：

    我还没有找到修复撕裂的解决方案。我最终从 scatch 重新安装了操作系统，认为这可以解决问题，因为这可能是由于戴尔 XPS 上之前安装的配置错误造成的。结果是System76告诉我的不是正常行为，即nvidia-settings寻找prime-supported，是标准行为，因为它只是在全新安装时执行此操作。另外，System76 要求我从 X11 切换到 Wayland，但我之前的安装中并未安装它。同样，全新安装默认情况下没有安装 Wayland。完整的 Nvidia 模式不够稳定，无法使用，因为 PopOS 22.04 上存在大量撕裂。我不知道它在其他发行版上是否更稳定。我恢复到混合，它更有用，即相当稳定。在混合模式下，Nvidia 参与并且可以通过nvtop.
