[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=none # 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. See the other options below. startup_mode=integrated # GPU mode to select when startup_mode=auto and the computer is running on battery. # Possible values: nvidia, integrated, hybrid, intel (deprecated, equivalent to integrated) startup_auto_battery_mode=integrated # GPU mode to select when startup_mode=auto and the computer is running on external power. # Possible values: nvidia, integrated, hybrid, intel (deprecated, equivalent to integrated) startup_auto_extpower_mode=nvidia [intel] # Driver to use for the Intel GPU. Possible values : modesetting, intel # To use the intel driver, you need to install the package "xf86-video-intel". driver=modesetting # Acceleration method (corresponds to AccelMethod in the Xorg configuration). # Only applies to the intel driver. # Possible values : sna, xna, uxa # Leave blank for the default (no option specified) accel= # Enable TearFree option in the Xorg configuration. # Only applies to the intel driver. # Possible values : yes, no # Leave blank for the default (no option specified) tearfree= # DRI version. Possible values : 2, 3 DRI=3 # Whether or not to enable modesetting for the nouveau driver. # Does not affect modesetting for the Intel GPU driver ! # This option only matters if you use nouveau as the switching backend. modeset=yes [amd] # Driver to use for the AMD GPU. Possible values : modesetting, amdgpu # To use the amdgpu driver, you need to install the package "xf86-video-amdgpu". driver=modesetting # Enable TearFree option in the Xorg configuration. # Only applies to the amdgpu driver. # Possible values : yes, no # Leave blank for the default (no option specified) tearfree= # DRI version. Possible values : 2, 3 DRI=3 [nvidia] # Whether or not to enable modesetting. Required for PRIME Synchronization (which prevents tearing). modeset=yes # Whether or not to enable the NVreg_UsePageAttributeTable option in the Nvidia driver. # Recommended, can cause poor CPU performance otherwise. PAT=yes # DPI value. This will be set using the Xsetup script passed to your login manager. # It will run the command # xrandr --dpi # Leave blank for the default (the above command will not be run). 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. Setting this flag to "yes" # will allow the loading of the nvidia driver. ignore_abi=no # Set to yes if you want to use optimus-manager with external Nvidia GPUs (experimental) allow_external_gpus=no # Comma-separated list of Nvidia-specific options to apply. # Available options : # - overclocking : enable CoolBits in the Xorg configuration, which unlocks clocking options # in the Nvidia control panel. Note: does not work in hybrid mode. # - triple_buffer : enable triple buffering. options=overclocking # Enable Runtime D3 (RTD3) Power Management in the Nvidia driver. 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=fine # 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.
