有些筆電接HDMI無法投影接D-SUB卻正常

近期買的筆電在用HDMI連接會議室投影機時，都會顯示沒有連接到設備，接D-SUB卻正常投影。其他舊筆電兩種連接方式都正常。

本來以為是中間有連接一些轉接頭的關係，後來才發現，是因為新筆電解析度很高，但投影機的太低，如果接上投影機時，是在"同步顯示"的狀態下，投影機的畫面就無法投影，要改成"僅第二個螢幕顯示"，或是把筆電的解析度降低，就可以正常投影了。

Recently purchased laptops using HDMI to connect to the projector will display "No device connected". D-SUB can be connected normally. Other old laptops can connect normally in both ways.

At first, I thought it was because of the adapters in the middle. Later, I found out that it was because the new laptop has a high resolution, while the projector is old and has a low resolution. If the projector is connected in "Synced display" mode, the projector's image cannot be projected. You need to change to "Only second monitor display" or lower the laptop's resolution to be able to project normally.

linux mount 沒反應後來出現 mount.nfs input/output error

有一台linux主機在重開機後要重新mount其他機器的分享資料夾，執行執令後，畫面上沒任何反應。

過了一下子才會出現 mount.nfs input/output error，這是因為 /etc/init.d/portmap 這個服務沒有啟動的關係，

先執行/etc/init.d/portmap status，確認該服務是stop。

接著用執行啟用的指令/etc/init.d/portmap start，就可以再執行mount的動作了。

A Linux host fails to mount a shared folder from another machine after a reboot. After executing the mount command, the screen is blank.

After a while, an error message "mount.nfs input/output error" appears. This is because the service "/etc/init.d/portmap" is not running.

First, execute the command "/etc/init.d/portmap status" to confirm that the service is stopped.

Then, execute the command "/etc/init.d/portmap start" to start the service. After that, you can mount the shared folder again.

VMWARE匯入OVA失敗-硬體系列 vmx-18 不受支援

在新建虛擬機，從esxi要匯入一個 ova檔時，最後一步出現錯誤:硬體系列 vmx-18 不受支援

原因是此ova是比較新的esxi建的，現在要匯入到比較舊的esxi所以無法支援，只要在esxi升級就行了。

When creating a new virtual machine, an error occurs in the last step when importing an ova file from ESXi: "Hardware series vmx-18 is not supported."

The reason for this error is that the ova was created with a newer version of ESXi and is now being imported to an older version of ESXi, which does not support the vmx-18 hardware series. The solution is to upgrade ESXi to a version that supports the vmx-18 hardware series.

更新KESS到最新版3.2後無法連線到中控台Server

將KESS升級到最新版後，連同Network Agent也一起更新到14版。

裝好後卻一直無法跟中控台連線，測了一下發現是Network Agent 有啟用，但連不到中控台。

原來是Network Agent 14版不支援比較舊的作業系統了，規格可參考下列的kaspersky官網說明

https://support.kaspersky.com/KSC/14.2/en-US/255797.htm

After upgrading KESS to the latest version, the Network Agent were also updated to version 14.

After installation, the connection to the central console was not possible. Testing revealed that the Network Agent were running, but could not connect to the central console.

It turned out that Network Agent version 14 no longer supports older operating systems. The specifications can be found in the following Kaspersky website documentation:

WIN10筆電突然麥克風無法收音

筆電突然無法收音，但裝置都還在。

重上驅動也沒用。

可以換個帳號登入試試，有時後是profile的問題，如果換個帳號登入，麥克風是正常的，重把有問題的使用者profile重建即可。

The Windows10 laptop microphone suddenly stopped working, but the device is still there.

Reinstalling the driver did not work.

You can try logging in with a different account. Sometimes it is a profile issue. If the microphone works normally when you log in with a different account, you can rebuild the user profile with the problem.
