![笔记本电脑连接的 VGA 显示器仅为镜像,无法独立检测。14.04](https://linux22.com/image/1049191/%E7%AC%94%E8%AE%B0%E6%9C%AC%E7%94%B5%E8%84%91%E8%BF%9E%E6%8E%A5%E7%9A%84%20VGA%20%E6%98%BE%E7%A4%BA%E5%99%A8%E4%BB%85%E4%B8%BA%E9%95%9C%E5%83%8F%EF%BC%8C%E6%97%A0%E6%B3%95%E7%8B%AC%E7%AB%8B%E6%A3%80%E6%B5%8B%E3%80%8214.04.png)
我知道这是常见现象,但我无法解释错误。此连接以前可以正常工作,但从那时到现在(大概 12 个月),我尝试运行 steam,但可能弄乱了我的驱动程序(我使用的是集成英特尔高清显卡)。任何建议都将不胜感激。
