[solaris 10] ip변경 후 재부팅하고나서부터 x-window가 뜨지 않습니다.

초기설치 및 몇번의 재부팅 까지는 X-Window가 잘 떳습니다.
하지만 IP를 변경하고 재부팅을 한 다음부터 X-window가 뜨지않고
아래와 같은 에러메시지를 뿌리고 있습니다.
최초부팅부터 X-Window가 뜨지 않았다면, 드라이버나 그래픽카드문제등을 의심해 볼 수
있겠지만.. 그렇지 않기때문에 해결점을 찾기가 더 어렵네요.

dtconfig -d
dtconfig -e
해 보았으나 똑같은 메시지만 뿌립니다....

혹시 같은 경험을 하신 분들이 있으신지요??
한수 지도 부탁드리겠습니다.
도와주셔요~~ ㅠㅠ

/var/dt/Xerror 에러는 아래와 같습니다. 검토 부탁드립니다.
