进不了X界面，大家帮帮忙！

一台客户的电脑，有两个问题：
问题一.用#startx进入x界面时，提示错误信息：
mktemp:connot create temp file /tmp/serverauth.lsVDRGLWjb:Read-only file system
/usr/bin/startx: line 158 connot create temp file for document: Read-only file system
xauth: error in locking authority file /root/.Xauthority
/usr/bin/startx: line 170 connot create temp file for document: Read-only file system

Fatal server error:
could not create lock file in /tmp/.tX0-lock

giving up
xinit: No such file or directory(errno 2):unable to connect to X server
xinit: No such process(erron 3): Server error
xauth: error in lockint authority file /root/.Xauthority

问题二：
在字符终端上，老是提示：INIT: Id "ssh" respawning too fast: disabled for 5 minutes

情况很急，大家帮帮忙了，在线等候，谢谢！！
