至少一年来，我一直在尝试使用 gnome shell 和 wayland 在我的 Fedora 笔记本电脑上使用 optimus 和 Geforce MX150 GPU 来运行 optimus。在早期版本中，我尝试过 bumblebee，但遇到了麻烦（虽然有一段时间我认为它已经运行了很长时间，但至少在 F31 中没有）。现在我升级到了 F32，我读到 optimus/nvidia gpu 不再需要 bumblebee，我只需使用环境变量即可__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia。所以我想试一试。我查看了https://rpmfusion.org/Howto/NVIDIA#Optimus还是没运气。在 Windows（双启动）下，它运行良好，所以这不是硬件问题。
如果我运行 glxinfo，我会收到以下错误：
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxinfo | grep vendor
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 150 (GLX)
Minor opcode of failed request: 24 (X_GLXCreateNewContext)
Value in failed request: 0x0
Serial number of failed request: 39
Current serial number in output stream: 40
不过，该卡似乎在那里，并且驱动程序已加载：

答案1
更新：恐怕我宁愿在 F32 上避免这种情况。
F34- 可以使用 nvidia + wayland，但需要更改配置：
编辑文件 /lib/udev/rules.d/61-gdm.rules 注释掉此行：DRIVER=="nvidia", RUN+="/usr/libexec/gdm-disable-wayland"
F35
注释掉此行（上面提到的文件）：SUBSYSTEM=="drm", KERNEL=="card[1-9]*", ENV{GDM_HAS_NVIDIA_DRIVER}=="1", RUN+="/usr/libexec/gdm-runtime-config set daemon WaylandEnable false" ACTION=="add", SUBSYSTEM=="module", KERNEL=="nvidia_drm", ATTR{parameters/modeset}=="N", RUN+="/usr/libexec/gdm-runtime-config set daemon WaylandEnable false"
F35 自gnome-session-40.1.1-3.fc35- 它应该可以与二进制驱动程序很好地配合。
