我正在运行 Xubuntu 14.04.3 LTS（值得信赖）。
当我尝试以主用户帐户登录时，屏幕会黑一秒钟，然后返回登录屏幕。但是，我可以以访客用户身份登录。我尝试分别chown登录和删除，~/.Xauthority因为这对其他人来说是个问题，但这没有帮助。
如果我使用终端（++）登录并Ctrl尝试运行某些命令（即，，），则每个命令都会出现以下错误：AltF1lscleargrep
-bash: /home/cameron/bin/ls: cannot execute binary file: Exec format error
但是，使用/bin/ls或/usr/bin/clear可以，就像使用 一样sudo。
这是输出/bin/cat ~/.xsession-errors：
/usr/sbin/lightdm-session: line 33: /home/cameron/bin/cat: cannot execute binary file: Exec format error
/usr/sbin/lightdm-session: line 34: /home/cameron/bin/truncate: cannot execute binary file: Exec format error

我认为您在主目录中提取了一个 ARM 根文件系统。您之所以会收到所有这些错误，是因为~/bin每当您尝试运行某些东西时，都会首先搜索，然后尝试运行 中的/bin外部二进制文件，而不是运行系统中的发行版二进制文件~/bin。
尝试重命名~/bin目录：
cd /home/cameron
/bin/mv bin bin.bkp
