我在 linux/ubuntu 14.04 上，我的用户目录可以在 中找到/.lyx。我能够将颜色主题粘贴进去，/.lyx/preferences但是当我尝试在 lyx 中更改首选项时，重新启动程序后更改就会丢失。
preferences我检查了文件和文件夹的权限，发现-rw-rw-rw-lyx 应该能够更改它们。我该怎么办？

解决方案：在偏好设置中使用“保存”按钮永久保存，而不是“应用”按钮。
你遇到了一个常见的困惑，表现为这LyX 错误。“应用”按钮仅用于将其应用于该 LyX 会话。如果您理解其中的区别，这是一个有用的功能，因为这样您就可以尝试各种偏好，而不必担心您会永久更改某些内容（并忘记如何恢复到之前的状态）。虽然这是一个有用的功能，但它给许多用户（包括我自己）带来了困惑。
