会发生什么

会发生什么

我读过很多关于 Ubuntu 中显示亮度键盘快捷键问题的帖子。大多数帖子都提供了针对 Ubuntu 14 或更早版本的解答,所以我想尽可能多地提供相关信息。

会发生什么

开机后,我登录后,亮度调节键盘快捷键无效,亮度调到最大。我注销(未重启),重新登录后,键盘快捷键有效。

应该发生什么

无论是第一次、第二次、第三次还是额外登录,亮度控制的键盘快捷键都应该有效,而无需注销并重新登录。

该文件由NVidia X 服务器设置应用程序正如您在文件注释头中所看到的,但用进行了修改,Option "RegistryDwords" "EnableBrightnessControl=1"然后保存到指定位置(因为我通过研究了解到这是存储这些文件的新方法.conf)。

结论

这比其他任何事情都更令人烦恼,但如果其他人也遇到过这种情况,或者知道我可以从哪里开始寻找解决方案,请告诉我。

非常感激!
