我搞砸了。
我使用的是HP Pavilion dv6000笔记本电脑,配备有nVidia GeForce 8400M GS显卡。我遇到了外部显示器分辨率的问题,Ubuntu显示管理器无法识别正确的显示器分辨率,所以我开始在nVidia X服务器设置中进行调整。我添加了X Screen 1并保存到X配置文件中。不知道怎么回事,我不小心关闭了内置显示器,现在无法再打开它。之后,我更新了显卡驱动程序,但问题仍然存在。
nvidia-smi输出:
我的猜测是我应该从xorg.conf中删除对Screen 1的所有引用,或者恢复此文件为原始文件。然而,xorg.conf.backup文件也不是原始文件,因为在解决这个问题时我多次重启了系统。
有任何想法如何修复这个问题,或者在哪里找到GeForce 8400M GS的原始xorg.conf文件吗?
