I typically use xrandr to switch configurations, and then bind each
configuration to a shortcut. Examples:
# Turn on just one screen:
bindsym $mod+comma exec "xrandr --output eDP1 --off --output DP1 --auto"
bindsym $mod+Control+comma exec "xrandr --output eDP1 --auto --output DP1
--mode 1920x1080"
# Select a particular resolution
bindsym $mod+period exec "xrandr --fb 1920x1080 --output eDP1 --mode
1920x1080"
# This will automatically activate all monitors
bindsym $mod+slash exec "xrandr --auto"
Make sure to replace eDP1, DP1, or HDMI3 with the actual monitor names
returned by xrandr.
One issue I run into is that if I have my laptop docked with a main monitor
on and the laptop monitor off, if the laptop is locked and I undock it, the
screensaver doesn't turn the laptop monitor on, so I have to unlock it with
no visual feedback.

Hi all,
I would like to mirror the screen of a laptop with an external monitor,
for instance to have a presentation. In other DEs this is usually provided
by an Fn key combination, but i3 ignores such signals. And is it possible
to complete switch off one of the monitors?
Thank you.
