【笔记】Gildas运行报错Invalid MIT-MAGIC-COOKIE-1 key

$ class

GILDAS Version: jul15a (01jul15 07:38 cest) (x86_64-ubuntu18.04-gfortran) executable tree

Invalid MIT-MAGIC-COOKIE-1 key

(class:4104): Gtk-WARNING **: 09:57:51.161: cannot open display: :0

图形程序界面显示出错

参考：https://unix.stackexchange.com/questions/199891/invalid-mit-magic-cookie-1-key-when-trying-to-run-program-remotely

解决方法：

$ xhost +local:

Invalid MIT-MAGIC-COOKIE-1 keyxhost: unable to open display “:0”

$ export DISPLAY=:1.0 即"display 1 at localhost"

然后运行程序即可。

出现这种问题的原因是程序或.bashrc中出现了“export DISPLAY=:0”，改为export DISPLAY=:1.0即可
