终端启动图形化程序界面时报 No protocol specified

[chengquansen]

有时候也会报这个：Invalid MIT-MAGIC-COOKIE-1 key

我发现，当我用数据线把手机和电脑连一起，然后手机打开 usb 共享网络给电脑用时，启动图像界面的程序就会报Invalid MIT-MAGIC-COOKIE-1 key，取消 usb 共享网络后，就报No protocol specified

虽然是这样子，好像想都不影响使用！

顺便说说另外一个问题
启动 qalculate-gtk，警告：AT-SPI: Could not obtain desktop path or name
下面是详细的打印信息

这个问题解决啦，附上链接：https://blog.csdn.net/linuxchyu/article/details/9745369

当使用与图像显示或显卡有关的程序时，会出现 No protocol specified 提示，这是当前用户没有权限访问 xhost 的原因，将当前用户添加到 xhost 的权限列表就可以了。

添加权限的命令是：xhost SI:localuser:“username”
