桌面調整

1. 解析度 1920X1080，設定 gnome 顯示 Resolution 為 120 dots per inch 及字型大小，使用的字型可以統一於 .fonts.conf 進行取代。

   system --> Preference --> Appearance --> Fonts --> Detials
   
   Resolution: 120 dots per inch
   

2. Firefox menu 及網址列 icon size 增大 120%：

   (1) Type abbout:config in the address bar and press Enter.
   (2) In the filter box, type or paste pix and pause while the list is filtered
   (3) Double-click layout.css.devPixelsPerPx and try changing its value to 1.2
   

3. 高解析度顯示，改用 Noto 字型並對所有字型預設開 antialias，關 hinting，hintstyle 為 hintslight，字型不會鋸齒狀且不會模糊。

4. gdm 登入畫面字型大小調整，先備份 gdm-simple-slave，這個檔案是二進位可執行檔，改錯則無法執行。取代字串 verbose 為 dpi 120， 數字 120 是三個字元，若要改成 96，則 96 後面要加一個空白字元。

   [root@dywmsi ~]# cp /usr/libexec/gdm-simple-slave /tmp/
   [root@dywmsi ~]# sed 's/verbose/dpi 120/g' -i /usr/libexec/gdm-simple-slave
