Linux
完全在 Nvidia 專用顯卡上執行您的 Linux（顯卡）？
我正在執行 ArcoLinux，幾個月來我一直在努力弄清楚如何在 Nvidia 專用 GPU 上完全執行我的Optimus 筆記型電腦。我該怎麼做呢？我聽說那裡有多種選擇，但我不知道如何解決！那麼如何在 Linux 上享受我強大的NVIDIA GeForce GTX 1650 Ti Mobile呢？
有什麼想法或設置可以幫助我在我的 Nvidia GPU 上執行任何與 GPU 相關的任務嗎？
我也有一段時間遇到這個問題，直到我發現了一個實用程序來完成這一切。您可以使用ArchWiki了解 Optimus 筆記型電腦的工作原理。然後你有多種選擇，但我建議執行optimus-manager 我用 Gnome 執行 ArcoLinux，我的規格也是：NVIDIA GeForce GTX 1650 Ti Mobile。我必須說它執行完美。到目前為止，我沒有遇到任何問題 - 至少 1 年。

optimus-manager --status如果您完全在專用卡上執行，這是應該給出的輸出：optimus-manager --status Optimus Manager (Client) version 1.4 Current GPU mode : nvidia GPU mode requested for next login : no change GPU at startup : nvidia Temporary config path: no這是我的
/etc/optimus-manager/optimus-manager.conf[optimus] # This parameter defines the method used to power switch the Nvidia card. See the documentation # for a complete description of what each value does. Possible values : # # - nouveau : load the nouveau module on the Nvidia card. # - bbswitch : power off the card using the bbswitch module (requires the bbswitch dependency). # - acpi_call : try various ACPI method calls to power the card on and off (requires the acpi_call dependency) # - custom: use custom scripts at /etc/optimus-manager/nvidia-enable.sh and /etc/optimus-manager/nvidia-disable.sh # - none : do not use an external module for power management. For some laptop models it's preferable to # use this option in combination with pci_power_control (see below). switching=bbswitch # Enable PCI power management in "integrated" mode. # This option is incompatible with acpi_call and bbswitch, so it will be ignored in those cases. pci_power_control=no # Remove the Nvidia card from the PCI bus. # May prevent crashes caused by power switching. # Ignored if switching=nouveau or switching=bbswitch. pci_remove=no # Reset the Nvidia card at the PCI level before reloading the nvidia module. # Ensures the card is in a fresh state before reloading the nvidia module. # May fix some switching issues. Possible values : # # - no : does not perform any reset # - function_level : perform a light "function-level" reset # - hot_reset : perform a "hot reset" of the PCI bridge. ATTENTION : this method messes with the hardware # directly, please read the online documentation of optimus-manager before using it. # Also, it will perform a PCI remove even if pci_remove=no. # pci_reset=no # Automatically log out the current desktop session when switching GPUs. # This feature is currently supported for the following DE/WM : # GNOME, KDE Plasma, LXDE, Deepin, Xfce, i3, Openbox, AwesomeWM, bspwm and dwm # If this option is disabled or you use a different desktop environment, # GPU switching only becomes effective at the next graphical session login. auto_logout=yes # GPU mode to use at computer startup. # Possible values: nvidia, integrated, hybrid, auto, intel (deprecated, equivalent to integrated) # "auto" is a special mode that auto-detects if the computer is running on battery # and selects a proper GPU mode.

PAT=yes # DPI value.

DPI=96 # If you're running an updated version of xorg-server (let's say to get PRIME Render offload enabled), # the nvidia driver may not load because of an ABI version mismatch.

While in hybrid mode, # this feature allows the Nvidia card to go into a low-power mode if it's not in use. # # IMPORTANT NOTES: # - The feature is still experimental # - It's only supported on laptops with a Turing GPU or above, and an Intel Coffee Lake CPU # or above (not sure about the state of support for AMD CPUs). # - if your Nvidia card also has an audio chip (for HDMI) or a USB port wired to it, they may not # function properly while in low-power mode # # For more details, see # https://download.nvidia.com/XFree86/Linux-x86_64/460.39/README/dynamicpowermanagement.html # # Available options: # - no (the default): RTD3 power management is disabled. # - coarse: the card only goes to low-power if no application is using it. # - fine: the card is also allowed to go to low-power if applications are using it but have not # actively submitted GPU work in some amount of time. dynamic_power_management=no # The Nvidia driver handles power to the video memory separately from the rest of GPU. # When dynamic_power_management=fine, this options controls the threshold of memory utilization # (in Megabytes) under which the memory is put in a low-power state. # Values over 200MB are ignored.
