1、前端代码

javascript 复制代码

<settings-toggle-button id="hardwareAcceleration"

        pref="{{prefs.hardware_acceleration_mode.enabled}}"

        label="$i18n{hardwareAccelerationLabel}">

      <template is="dom-if" if="[[shouldShowRestart_(

          prefs.hardware_acceleration_mode.enabled.value)]]">

        <cr-button on-click="onRestartClick_" slot="more-actions">

          $i18n{restart}

        </cr-button>

      </template>

</settings-toggle-button>

2、c++代码

cpp 复制代码


// Set to true if hardware acceleration mode is enabled on this browser.

inline constexpr char kHardwareAccelerationModeEnabled[] =

    "hardware_acceleration_mode.enabled";

chrome\browser\gpu\gpu_mode_manager.cc

cpp 复制代码

// static
void GpuModeManager::RegisterPrefs(PrefRegistrySimple* registry) {
  registry->RegisterBooleanPref(
      prefs::kHardwareAccelerationModeEnabled, true);
  registry->RegisterBooleanPref(
      prefs::kHardwareAccelerationModePrevious, true);
}

修改此kHardwareAccelerationModeEnabled值即可控制。
