HP小機有兩塊獨顯，一塊整合顯示卡，顯示器與獨顯連線時提示：RV100 113-85538-100 BIOS，連線不上主機，接整合顯示卡時是OK的

沒有接觸過HP小機，都不知如何下手

解決方法：

1、檢查主機顯示板沒有報錯燈顯示

2、檢查dmesg沒有報錯

3、檢查/var/adm/syslog/syslog.log沒有報錯

4、剛開始是以為獨顯壞了，更換獨顯，天公不作美啊，還是同樣的報錯，最後回過頭想想兩塊獨顯同時壞的可能性很小；

5、檢查DT報錯日誌

7、透過第5、6步都提示滑鼠有問題，想了想小機上沒有接滑鼠會不會有關係，不管三七二十一把自己電腦的滑鼠接上，重啟DT服務

# ps -ef | grep dtlogin

root 2882 2858 0 11:09:05 ? 0:00 /usr/dt/bin/dtlogin

#kill -9 2882

#cd /usr/dt/bin/

#./dtconfig -reset重置DT配置檔案

done

dtlogin config resources reloaded.

# ./dtconfig -start啟動DT程式

done

dtlogin startup complete.

# ps -ef|grep dtlogin

root 5483 5467 0 00:43:23 console 0:00 /usr/dt/bin/dtlogin

root 5485 1968 0 00:43:31 console 0:00 grep dtlogin

重做第5、6步還是有報錯

8、會不會是配置檔案有問題呢？有這個可能，正好一臺機子配置、應用是一樣的機子，於是從另一臺機子把配置檔案複製到本機

#cd /etc/X11/替換檔案：XF86Config,當然替換前先備份好原來的配置檔案

重啟服務，還是有報錯

9、死馬當活馬醫了，求助同事想出一個更餿的主意,把配置檔案刪除了，然後重啟機子,以為會重新生成一個配置檔案，結果沒生成，還是報錯

10、既然是提示Mouse0: cannot open input device,那我可不可以把配置檔案裡有把mouse的都註釋呢？值得一做，註釋後提示配置檔案錯誤，真扯蛋了，到止已經

處理了差不多兩天，我還要不要回家過週末了……

11、仔細檢查配置檔案發現滑鼠使用的是PS口的，但是主機面沒有PS介面啊，怎麼辦呢，能不能改配置檔案，那是肯定的，試著修改

修改前：

Section "InputDevice"

Identifier "Mouse0"

Driver "mouse"

Option "Protocol" "PS/2"

EndSection

修改後：

Section "InputDevice"

Identifier "Mouse0"

Driver "mouse"

Option "Protocol" "IMPS/2"

EndSection

重置配置，重啟服務還是報錯，要瘋了

12、冷靜下來想想，既然有一臺機子跟它一樣的，為什麼另一臺沒有問題呢，配置檔案是一樣的，說明配置檔案應該沒有問題，為什麼呢……

想想使用者的需求，是想直接把顯示器接到獨顯上，而另一臺能顯示並不是直接連獨顯，是透過KVM連線，那我能不能把另一臺的KVM連線的滑鼠介面插到有問題的

主機上呢？不試不知道，試了自己成了白痴，老天還真的顯靈了。

原因：原來是由於KVM可以把USB屬性的介面協議轉換為PS協議的，而DT啟需要的配置檔案需要使用PS協議的滑鼠，KVM正好提供了這個轉換功能

結論：最後搞下來回想起來覺得很簡單，不就換個介面嘛，可當時真的是花了不少功夫處理，知識有限，學得不深入真是杯具

獨顯接顯示器報錯提示：Mouse0: cannot open input device
