新用户配置

我想确保我的 Dropbox 目录不会受到无意更改。因此，我对目录和文件执行了以下操作：

chown -R dropbox:dropbox Dropbox

我的想法是，我在一个普通用户下工作，我们将其命名为 USER。然后我以 dropbox 用户身份启动 dropbox：

sudo -u dropbox dropbox start

但是有一个错误，我不知道如何处理：

Unable to access the X Display, is $DISPLAY set properly?

我怎样才能正确地创建新用户以实现此目标？当前/home/dropbox目录中的唯一配置文件来自/etc/skel/目录。

更新 Eliah Kagan 的建议：

我无法使用 gksu 启动 dropbox，当我尝试这样做时，出现以下信息：

gksu -u dropbox dropbox start -i
gksu: option requires an argument -- 'i'

在 dropbox 用户下：

dropbox start -i

此错误表明用户图形环境配置有问题。

答案1

您正在使用的 Dropbox 客户端需要访问 X 会话，但您的用户没有该会话的权限。有一个官方的 Dropbox CLI这可能对你有帮助，但效果可能会有所不同。

答案2

正如 Bryan Agee 所说，dropbox这是一个图形程序，因此你不应sudo直接使用以 root 身份运行它。

但是，只要您操作正确，以另一个用户身份以图形方式运行程序就不会有任何问题：

gksu -u dropbox dropbox start

需要明确的是，这应该可行，其中sudo -u ...没有。（阻止在中创建root-owned（或在本例中dropbox为 -owned）配置文件你的主目录并不是gksu/gksudo和之间的唯一区别sudo；前者也能.Xauthority正确处理，这可能是阻止您“访问 X 显示器”的原因。）
