Place this code in your ~/.bashrc file to be able to call xreset from the command line:
xreset () {
# Reset xrandr to normal, first use: xrandr | grep " connected "
# HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 1107mm x 623mm
# eDP-1-1 connected primary 1920x1080+3840+2160 (normal left inverted right x axis y axis) 382mm x 215mm
# DP-1-1 connected 3840x2160+1920+0 (normal left inverted right x axis y axis) 1600mm x 900mm
xrandr --output HDMI-0 --mode 1920x1080 --pos 0x0 --rotate normal \
--fb 1920x1080 --panning 1920x1080 \
--output eDP-1-1 --mode 1920x1080 --pos 3840x2160 --rotate normal \
--primary \
--output DP-1-1 --mode 3840x2160 --pos 1920x0 --rotate normal
# --panning option added because HDMI-0 was mirroring all other monitors
# and "panning" back and forth. --fb option added next day.
} # xreset
Or if you prefer to create an .sh file use this:
#!/bin/bash
# Reset xrandr to normal, first use: xrandr | grep " connected "
# HDMI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 1107mm x 623mm
# eDP-1-1 connected primary 1920x1080+3840+2160 (normal left inverted right x axis y axis) 382mm x 215mm
# DP-1-1 connected 3840x2160+1920+0 (normal left inverted right x axis y axis) 1600mm x 900mm
xrandr --output HDMI-0 --mode 1920x1080 --pos 0x0 --rotate normal \
--fb 1920x1080 --panning 1920x1080 \
--output eDP-1-1 --mode 1920x1080 --pos 3840x2160 --rotate normal \
--primary \
--output DP-1-1 --mode 3840x2160 --pos 1920x0 --rotate normal
# --panning option added because HDMI-0 was mirroring all other monitors
# and "panning" back and forth. --fb option added next day.
Save to a file and mark it executable with chmod a+x filename
First you need to discover you monitor properties with:
xrandr | grep " connected"
Then using reported properties change the xreset function accordingly.
