Install dedicated AMD drivers for laptop S540

Problems

Laptop S540 has dedicated AMD 4800u integrated graphics, at first, I downloaded the driver from the lenovo official site but recently I want to upgrade the graphics card following AMD's official driver, which is more update, but everytime after the upgrade, Windows 11 automatically revert the old version driver making the new AMD driver being warned with not compatiable.

Solutions

The whole concept is to prevent Windows from checking and changing the driver automatically.

1. Navigate to Device Properties and find the AMD graphics hardware, click `XXX Grahpics Properties`  

At the same time, open Local Group Policy Editor and navigate to Administrative Templates > System > Device Installation > Device Installation Restrictions, find and edit the below entry

Enable the settings above with the entry values shown in Device Properties.

Apply the settings for each driver upgrade, disable the settings next time when a new driver update is needed

[requireJS] Case Study: Working With AngularJS

Struggling for 2 days, I finally make myself clear with the combination of angularJS and requireJS. I will note down with examples.


Target

• To load controllers, directives of AngularJS through requireJS.
  
  
• Enjoy the benefits of requireJS on AngularJS

Files Included

• main.js
• Centralize all the js loading by one single main js file.
  
  
• Specifying the dependencies of each module when loaded. E.g.: Bootstrap depends on jQuery
  
  
• insiderApp.js
• To define the Angular main insiderApp module
  
  
• controller.js
• To define the Angular controller module
  
  
• step0.html
• The Angular view

Coding

main.js

require.config({
 paths: {
  'jquery' : 'lib/jquery.min',
  'bootstrap' : 'lib/bootstrap.min',
  'bootstrap_select' : 'lib/bootstrap-select',
  'stepOne' : 'core/stepOne',
  'angular' : 'lib/angular',
  'angular-animate' : 'lib/angular-animate',
  'angular-route' : 'lib/angular-route',
  'controller' : 'controllers/controller'
 },
 
 //we do not add AMD-compliant script here!!
 shim: {
  "bootstrap" : { "deps" : ['jquery'] },
  'bootstrap_select' : { "deps" : ['jquery', 'bootstrap'] },
  'stepOne' :  { "deps" : ['jquery','bootstrap_select'] },
  'angular' : {
   exports : 'angular'
  },
  'angular-animate' : {
   "deps" : ['angular'],
   exports : 'angular-animate'
  },
  'angular-route' : { 
   "deps" : ['angular'],
   exports : 'angular-route'
  },
 },
 //for debug
 urlArgs: "bust=" + (new Date()).getTime() 
});


require(["jquery", "bootstrap", "bootstrap_select", "stepOne", "insiderApp", "angular", "controller"], function() {
 //requirejs sugar function >> Avoid putting all modules to the parameters
 var angular = require('angular')

 var csArr = ["/css/bootstrap-select.min.css", "/css/bootstrap.min.css", "/css/psliteM.css"];
 
 //manually start over insiderApp for angularJS, no need to put ng-app in html file
 angular.bootstrap(document,["insiderApp"]);
});

insiderApp.js

define(["angular", "angular-route", "angular-animate"],function(angular){
 var insiderApp = angular.module("insiderApp",["ngRoute", "ngAnimate"]);
 //routing
 insiderApp.config(['$routeProvider','$locationProvider',function($scope,$routeProvider,$locationProvider){
  
 }]);
 
 return insiderApp;
});

controller.js

//controller
define(['insiderApp'],function(insiderApp){
 insiderApp.controller('insiderControl', ['$scope', function($scope){
  //store all the required images path here
  $scope.menuImages = [
                     {
                      lm : './images/info.png',
                      width : '200px', 
                     },
                     {
                      mid : './images/setting.png',
                      width : '200px',
                     },
                     {
                      rm : './images/tv.png',
                      width : '200px',
                     },
                    ];
 }]);
});

Points to Note

• main.js
• Some tutorials will use require.config and we may also have requirejs.config, they are basically the same
  
  
• Requirejs object is used to setup 
• Dependencies of different modules
• Remember only non-AMD script is allowed to put in the deps parameters for dependency loading.
  
  
• Module exports as global variables for use of other modules
  
  
• Define the exact path of the js files
  
  
• require(["jquery", "bootstrap", "bootstrap_select", "stepOne", "insiderApp", "angular", "controller"]....
• jquery, bootstrap etc. is the self-defined name of js scripts to load, they are loaded in order
  
  
• We must load the controller module for the AngularJS controller to work properly
  
  
• Inside require function we have a second require function,which is called sugar function, it only loads the required modules for use inside the function, if you don't need it, you are NOT required to include in function parameters.
  
  
• angular.bootstrap is to manually trigger the start of angularJS, which is highly recommended to use when cooperate with requireJS
• When this was set, NO exists in the html view or AngularJS will throw errors
  
  
• insiderApp.js
• define(["angular", "angular-route", "angular-animate"],function(angular){
• Normally, we will ignore the first parameter of the define function and let requireJS to use the file name as the module name (recommended)
  
  
• Second array parameter tells requireJS that insiderApp module requires angular, angular-route and angular-animate to be loaded before executing the insiderApp module
  
  
• function parameter "angular" is returned by the angular function, this object is for the implementation of insiderApp
  
  
• Return the insiderApp variable or not depends on whether or not other modules need insiderApp, normally you need to return it.
  
  
• var insiderApp = angular.module("insiderApp",["ngRoute", "ngAnimate"]);
  Just like usual, start the angular module, we can do any configuration of the angular object in this file.
  
  
• controller.js
• Just like usual, controller of the Angular object
  
  
• define(['insiderApp'],function(insiderApp)...
• Controller rely on insiderApp for adding controller to the Angular module, so we need to put insiderApp to the array and use it inside the function
  
  
• insiderApp.controller('insiderControl', ['$scope', function($scope){...
• Do all the work of Angular controller as usual
  
  
• step0.html
• Main view
  
  
• NO here as we have already bootstrapped it manually in main.js
