ASUS TUF A15 FA506NC

• GPU switching to the nvidia card works fine through supergfxd.
• Power profiles autoswitch through asusctl in tandem with power-profiles-daemon.
• The batter charge limit configuration through ../battery.nix did not work, setting a limit through asusd works.

Configuring AsusCTL

To declaratively configure asusd you can control the whole config file through the asusd service (same for fan curves and keyboard leds):

services.asusd.asusdConfig.text = ''
  (
      charge_control_end_threshold: 80,
      base_charge_control_end_threshold: 80,
      disable_nvidia_powerd_on_battery: true,
      ac_command: "",
      bat_command: "",
      platform_profile_linked_epp: true,
      platform_profile_on_battery: Quiet,
      change_platform_profile_on_battery: true,
      platform_profile_on_ac: Performance,
      change_platform_profile_on_ac: true,
      profile_quiet_epp: Power,
      profile_balanced_epp: BalancePower,
      profile_custom_epp: Performance,
      profile_performance_epp: Performance,
      ac_profile_tunings: {
          Performance: (
              enabled: false,
              group: {},
          ),
          Quiet: (
              enabled: false,
              group: {},
          ),
          Balanced: (
              enabled: false,
              group: {},
          ),
      },
      dc_profile_tunings: {
          Quiet: (
              enabled: false,
              group: {},
          ),
          Balanced: (
              enabled: false,
              group: {},
          ),
          Performance: (
              enabled: false,
              group: {},
          ),
      },
      armoury_settings: {},
  )
'';

Here you can set the battery charge limit and other settings like which profile to use on batter and which on power.

You may also want to enable thermald and powertop for the optimizations mentioned in https://nixos.wiki/wiki/Laptop.

services.thermald.enable = true;
powerManagement.powertop.enable = true;
