i3wm Second Display Only

Sudah 3 hari saya memakai i3wm di mesin arch linux saya. Bukan apa-apa sih, hanya iseng saja. Kebetulan hari ini, saya menghubungkan mesin ke external monitor yang resolusinya lebih besar yaitu 1440x900.

Sempat bingung, bagaimana caranya agar display di laptop mati, dan eksternal display ON karena secara default saya berada dalam mode mirror. Ternyata caranya cukup simple.

1. jalankan xrandr bash-script [sumarsono@mesin-arch ~]$ xrandr Screen 0: minimum 8 x 8, current 1440 x 900, maximum 32767 x 32767 LVDS1 connected primary (normal left inverted right x axis y axis) 1280x800 59.99 + 50.00
   1024x768 60.00
   800x600 60.32 56.25
   640x480 59.94
   640x400 60.00
   DP1 disconnected (normal left inverted right x axis y axis) DP2 disconnected (normal left inverted right x axis y axis) DP3 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) VGA1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 420mm x 260mm 1440x900 59.90*+ 1280x1024 60.02
   1280x800 59.81
   1152x864 75.00
   1280x720 60.00
   1024x768 75.03 60.00
   832x624 74.55
   800x600 75.00 60.32 56.25
   640x480 75.00 59.94
   720x400 70.08
   VIRTUAL1 disconnected (normal left inverted right x axis y axis) [sumarsono@mesin-arch ~]$

2. jalankan perintah berikut agar VGA1 hidup dab LVDS1 Matikan
bash-script
xrandr --output VGA1 --mode 1440x900 --output LVDS1 --off

3. Profit !
