苦命的小編又接到新任務，要在工業PC上開發系統，限定使用Linux 當然我選擇安裝我的最愛Ubuntu 18.04 但因為會用到觸控螢幕的功能，18.04裝完沒辦法用觸控 不過試16.04是可以的；這表示應該有驅動程式可以裝，以下為我的解決流程。
先看看目前輸入設備有那些
指令：xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ eGalax Inc. USB TouchController id=17 [slave pointer (2)]
⎜ ↳ eGalaxTouch Virtual Device for Single id=21 [slave pointer (2)]
⎜ ↳ PixArt USB Optical Mouse id=13 [slave pointer (2)]
⎜ ↳ Plus More Enterprise LTD. USB-compliant keyboard Consumer Control id=11[slave pointer (2)]
⎜ ↳ Plus More Enterprise LTD. USB-compliant keyboard Mouse id=14 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ Plus More Enterprise LTD. USB-compliant keyboard id=9 [slave keyboard (3)]
看到了關鍵字 eGalax Inc. USB TouchController
上官網找驅動程式吧！

先給於執行權限 chmod a+x setup.sh
執行過程如下：
./setup.sh

裝完就可以觸控了…
後記心得：凡事追根究底別輕易放棄才能航向偉大的航道…如果當初選擇重灌 16.04 雖然觸控可以用了，但你永遠也不知在Ubuntu中驅動怎麼裝，放棄很簡單堅持才固難 與大家共勉之～
