当我跑步时:
xterm
显示以下文本:
Warning: This program is an suid-root program or is being run by the root user.
The full text of the error or warning message cannot be safely formatted
in this environment. You may get a more descriptive message by running the
program as a non-root user or by removing the suid bit on the executable.
xterm: Xt error: Can't open display: %s
xterm: DISPLAY is not set`
我不知道问题出在哪里。你能帮忙解决这个问题吗?
答案1
您没有xterm
在 GUI 下运行。GUI(X Window 系统、Wayland 等)将DISPLAY
环境变量设置为指向活动显示。在DISPLAY
未设置的文本终端中,没有 GUI,因此xterm
无法工作。
