Question

当我制作一个简单的窗口时，它会给我一个错误，我不明白为什么！我在Linux Mint 64位上。（戴尔Inspiron 1764）

这是错误：

org.lwjgl.LWJGLException: X Error - disp: 0x7f81187c9a20 serial: 93 error: GLXBadFBConfig request_code: 156 minor_code: 34
at org.lwjgl.opengl.LinuxDisplay.globalErrorHandler(LinuxDisplay.java:321)

at renderEngine.DisplayManager.createDisplay(DisplayManager.java:27)
at engineTester.MainGameLoop.main(MainGameLoop.java:10)

Exception in thread "main" java.lang.IllegalStateException: Cannot determine close requested state of uncreated window
at org.lwjgl.opengl.Display.isCloseRequested(Display.java:549)
at engineTester.MainGameLoop.main(MainGameLoop.java:14)

这是我的代码：

package engineTester;

import org.lwjgl.opengl.Display;

import renderEngine.DisplayManager;

public class MainGameLoop {

public static void main(String[] args) {
    DisplayManager.createDisplay();

        while(!Display.isCloseRequested()) {
            //game logic
            //render
            DisplayManager.updateDisplay();
        }

        DisplayManager.closeDisplay();
    }

}

然后另一个类是：

package renderEngine;

import org.lwjgl.LWJGLException;
import org.lwjgl.opengl.ContextAttribs;
import org.lwjgl.opengl.Display;
import org.lwjgl.opengl.DisplayMode;
import org.lwjgl.opengl.GL11;
import org.lwjgl.opengl.PixelFormat;  
import org.lwjgl.test.applet.OpenGL;

public class DisplayManager {

private static final int WIDTH = 1000;

private static final int HEIGHT = 700;

private static final int FPS_CAP = 120;

public static void createDisplay() {

    ContextAttribs attribs = new ContextAttribs(3,2);
        attribs.withForwardCompatible(true);
        attribs.withProfileCore(true);

        try {
            Display.setDisplayMode(new DisplayMode(WIDTH, HEIGHT));
            Display.create(new PixelFormat(), attribs);
            OpenGL opengl = new OpenGL();
            GL11.glViewport(0, 0, WIDTH, HEIGHT);
        } catch (LWJGLException e) {
            e.printStackTrace();
        }
    }

    public static void updateDisplay() {
        Display.sync(FPS_CAP);
        Display.update();
    }

    public static void closeDisplay() {

        Display.destroy();

    }

}

经过多方面的努力，我终于决定阅读Minecraft的源代码，看看他们是如何创建自己的OpenGL窗口的。我把它放在我的代码中，现在窗口打开了！

如果遇到问题，要使其正常工作，请替换

Display.create（new PixelFormat（），attribs）;

与

Display.create（new PixelFormat（）。withDepthBits（24））;

窗口打开时出错？
