/var/log/syslog我在 Ubuntu 18.04 上，有时发现我无法再从桌面上的图标打开任何文件夹。尝试时出现以下错误：
$ cat /var/log/syslog | tail -3

尽管如此，从 nautilus 窗口打开桌面文件夹还是可行的，在终止并重新启动 nautilus-desktop 后也是如此。重新启动仅在下次重启前有效：
$ killall nautilus-desktop
$ nautilus-desktop &
但我更希望修复错误，而不是解决问题...有什么想法吗？谢谢！
进一步的日志
终止、重新启动并从桌面图标打开文件夹会导致以下结果/var/log/syslog：

答案1
移除nautilus表格Startup Applications
我无法解决这个问题，但我找到了触发器，‘禁用’了它并报告了漏洞：当 nautilus 设置为“启动启动”时，桌面上的文件夹无法打开Startup Applications。一旦我从Startup-app-list 中删除 nautilus 并重新启动，文件夹就会正常打开。这个错误是可重现的，我在 Ubuntu 18.04 和 18.10 上遇到过它。
至少现在可以绕过该错误，直到它被修复。
