我里面有一个目录。我如何删除它。
~/.local/share/Trash/files$ ls devices/
reg-dummy
~/.local/share/Trash/files$ ls devices/reg-dummy/
subsystem
~/.local/share/Trash/files$ ls devices/reg-dummy/subsystem/
devices
还
~/.local/share/Trash/files$ find devices/ | head -n 20
devices/
devices/reg-dummy
devices/reg-dummy/subsystem
devices/reg-dummy/subsystem/devices

另外，虽然我的大脑无法解决停机问题，但似乎sudo rm -rf devices永远不会产生输出。
~/.local/share/Trash/files$ sudo rm -rf devices
^C~/.local/share/Trash/files$
同样的事情perl -e 'use File::Path qw(remove_tree); remove_tree("$ENV{HOME}/.local/share/Trash/files/devices")'。同样的事情du -s devices/。对于同样的事情du -sch ~/.local/share/Trash/
其他命令
$ cd ~/.local/share/Trash/files/devices/reg-dummy/subsystem/devices/
$ ls -ldi
8131921 drwxr-xr-x 3 theking theking …我有一台运行 Ubuntu Server 12.04 LTS 的机器，但本地监视器出现问题。我使用的戴尔平板仅在计算机运行时显示此消息：“无法显示此视频模式”，然后显示信息：“最佳分辨率 1280x1024 60Hz”。我是完全通过命令行使用操作系统的新手，但我学得很快。:) 我可以通过 SSH 很好地访问服务器，所以使用它不是问题。不过，就其目前所处的位置而言，在本地使用计算机会方便很多。我只是想知道如何通过 SSH 将本地屏幕分辨率更改为我的显示器可用的分辨率。谢谢你的时间！
顺便说一句：我也尝试过切换显示器，但仍然有同样的问题。
另外顺便说一句：我试着输入xrandr命令，我得到的只是：Can't open display
我有一台爱普生完美 v19 扫描仪。我有iscan-data，iscan和sane安装。当我运行 iscan 时，它说：
检查打印机状态
Xsane 也不认识它。
如何扫描？
所以我用 Xfce （使用 crouton）安装了 Ubuntu 并尝试运行 synaptic 并遇到了以下问题：
$ synaptic-pkexec

我使我的用户成为 root 用户（我可以使用安装和卸载东西apt-get）。怎么了？
