i3 and xinerama

23 Jul 2010

**Update Feb/2014: ** I’ve created a dmenu script who lists and configures automatically available monitors.

One of the main reasons I decided to stick with i3-wm over wmii was the improved xinerama support, that is the hability to use several screens at the same time, can you believe there are some window managers who don’t do it?, me neither 😳

For example, if I were to clone the video output from my laptop screen to a video projector I could use:

$ xrandr --output VGA1 --mode 1024x768 --same-as LVDS1

Or if were to extend my virtual work place, I could execute:

$ xrandr --output VGA1 --mode 1024x768 --right-of LVDS1

xrandr accepts plenty of options, refer to the man page for more details.
