[已解决]optimus-manager 启动失败，nvidia驱动无法运行

自从安装好optimus-manager 之后我就一直没有更改过它，但今天我发现optimus-manager 的图标在状态栏消失了，手动重启optimus-manager 时报了这样的错误：

ERROR: the latest GPU setup attempt failed at Xorg pre-start hook.
Log at /var/log/optimus-manager/switch/switch-20240512T192654.log
Cannot execute command because of previous errors.

其指向的log文件是这样的：

[31] INFO: # Xorg pre-start hook

The above exception was the direct cause of the following exception:

nvidia-smi

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

我尝试完全卸载重新安装，但还是启动不了，也尝试过https://bbs.archlinux.org/viewtopic.php?id=255752这里的解决方法，但都没有效果。

Re: [已解决]optimus-manager 启动失败，nvidia驱动无法运行

你重新安装了啥？
modinfo nvidia 和 pacman -Qs nvidia 看看？

我重新安装了optimus-manager和optimus-manager-qt

modinfo nvidia:

modinfo: ERROR: Module nvidia not found.

pacman -Qs nvidia:

local/egl-wayland 2:1.1.13-1
    EGLStream-based Wayland external platform
local/lib32-nvidia-utils 550.78-1
    NVIDIA drivers utilities (32-bit)
local/libvdpau 1.5-2
    Nvidia VDPAU library
local/libxnvctrl 550.78-1
    NVIDIA NV-CONTROL X extension
local/nvidia 550.78-2
    NVIDIA drivers for linux
local/nvidia-prime 1.0-4
    NVIDIA Prime Render Offload configuration and utilities
local/nvidia-settings 550.78-1
    Tool for configuring the NVIDIA graphics driver
local/nvidia-utils 550.78-1
    NVIDIA drivers utilities

应该是内核的问题，我刚刚切换了一下内核，发现又可以用了....   ：|
我刚刚试了一下，linux-zen、linux-lts都不能运行，linux 6.8.9.arch1-2就没有问题。

Re: [已解决]optimus-manager 启动失败，nvidia驱动无法运行

你只装了 nvidia，这个就是给 linux 包用的。-lts 需要装 nvidia-lts。-zen 不提供编译好的 nvidia 模块。你可以装 nvidia-dkms 但就是每次它们更新会在你本地编译。
