Forcing tear free on all outputs for the screen using xrandr command.
This only works when supported by the driver. (Only AMD as far as I know)
Manually this can be done using the following command when the output name is known.
xrandr --output DisplayPort-0 --set "TearFree" on
Use this command to get the "TearFree" status of all outputs.
xrandr --prop | less
Get all connected outputs using command line.
xrandr --prop | grep '^[A-Z][A-Za-z]*-[0-9]\sconnected\s' | awk '{print $1}'
Command line to set all at once.
for out in $(xrandr --prop | grep '^[A-Z][A-Za-z]*-[0-9]\sconnected\s' | awk '{print $1}') ; do xrandr --output ${out} --set "TearFree" on ; done
Create you own command and put the following bash script in file tear-free.sh in your own user bin directory.
editor ~/bin/tear-free.sh
Insert the next text to the file.
#!/bin/bash
if [[ -z "$1" ]] ; then
echo "Usage: $0 <mode>"
echo "Sets tear free mode on screen outputs."
echo "Where mode can be 'off', 'on' or 'auto'."
exit 1
fi
# Set each output of the current screen to the passed mode.
for out in $(xrandr --prop | grep '^[A-Z][A-Za-z]*-[0-9]\sconnected\s' | awk '{print $1}')
do
xrandr --output ${out} --set "TearFree" "${1}" 2> /dev/null
result=$?
#echo "xrandr --output ${out} --set \"TearFree\" \"${1}\" => ${result}"
if [[ $result != 0 ]] ; then
echo "Not supported on this device output '${out}' !"
fi
done
