kemudian tinggal jalankan

xrandr –output CRT1 –left-of LVDS

kalo ada eror seperti ini

xrandr: screen cannot be larger than 1920×1920 (desired size 3840×1080)

kita harus configurasiin si xorg.conf

1. Backup dulu file xorg.conf

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.confbackup

2. Buka file xorg.conf

sudo leafpad /etc/X11/xorg.conf

3. Kemudian akan muncul konfigurasi defaultnya seperti ini

Section "Screen"
    Identifier  "Default Screen"
    DefaultDepth    24
EndSection

Section "Module"
    Load    "glx"
EndSection

ubah konfigurasi tersebut menjadi

Section "Screen"
    Identifier  "Default Screen"
    DefaultDepth    24
    SubSection "Display"
        Virtual 3840 1920
    EndSubSection
EndSection


Section "Module"
    Load    "glx"
EndSection

5. restart xubuntu dan lakukan perintah

 xrandr

dilanjutkan

xrandr --output CRT1 --left-of LVDS
