Ini buat pengguna xubuntu yang bermasalah ketika mencoba dual monitor, buka terminal dan jalankan ini
xrandr
kemudian akan ada output seperti ini
Screen 0: minimum 320 x 200, current 2806 x 900, maximum 3840 x 1920 LVDS connected 1366x768+0+0 (normal left inverted right x axis y axis) 309mm x 173mm 1366x768 60.0*+ 1360x768 60.0 1280x768 60.0 1280x720 60.0 1024x768 60.0 1024x600 60.0 800x600 60.0 800x480 60.0 640x480 60.0 DFP1 disconnected (normal left inverted right x axis y axis) CRT1 connected 1440x900+1366+0 (normal left inverted right x axis y axis) 408mm x 255mm 1440x900 59.9*+ 1280x1024 75.0 60.0 1280x960 60.0 1280x800 60.0 1152x864 75.0 59.9 1280x768 60.0 1280x720 60.0 1024x768 75.0 70.1 60.0 1024x600 75.0 70.1 60.0 800x600 72.2 75.0 60.3 56.2 800x480 72.2 75.0 60.3 56.2 640x480 75.0 72.8 67.0 59.9
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
