现象
ssh登录Ubuntu时，速度很慢，输出信息如下：

/usr/bin/xauth: timeout in locking authority file /home/book/.Xauthority
book@100ask:~$
可以看到出错信息为：
/usr/bin/xauth: timeout in locking authority file /home/book/.Xauthority
解决方案
查看当前用户读写权限：
（备注，此处用户是book）
book@100ask:~$ cd ..
book@100ask:/home$ ll
total 36
drwxr-xr-x 6 root root 4096 Nov 3 20:37 ./
drwxr-xr-x 26 root root 4096 Nov 3 20:30 ../
dr-xr-xr-x 39 book book 4096 Oct 29 04:05 book/
drwxr-xr-x 24 gerrit gerrit 4096 Nov 4 04:34 gerrit/
drwx------ 2 root root 16384 Feb 20 2019 lost+found/
drwxr-xr-x 20 nano nano 4096 Nov 4 20:48 nano/
book@100ask:/home$
我的Ubuntu有三个用户，分别为 book 、gerrit、nano
从上图结果可以看出，book文件夹缺少写w权限
解决方案：
book@100ask:/home$ sudo chmod 755 book/
book@100ask:/home$ ll
total 36
drwxr-xr-x 6 root root 4096 Nov 3 20:37 ./
drwxr-xr-x 26 root root 4096 Nov 3 20:30 ../
drwxr-xr-x 39 book book 4096 Oct 29 04:05 book/
drwxr-xr-x 24 gerrit gerrit 4096 Nov 4 04:34 gerrit/
drwx------ 2 root root 16384 Feb 20 2019 lost+found/
drwxr-xr-x 20 nano nano 4096 Nov 4 20:48 nano/
book@100ask:/home$
再次ssh登录到book用户，报错消失，也不会卡顿：

book@100ask:~$
book@100ask:~$
此问题同时还会导致，Ubuntu无法进入book用户的Gnome界面，而其他用户Gnome界面正常！
