Mostly rotate the X and Y axis.
My method is probably more simple-minded that Nicolas's. It doesn't handle VCs (non-graphical logins) for which I have manual scripts. My ~/.xsession calls ~/bin/xinput-xsession which contains the following fragments: Printing="printf" Xinput="xinput" Unique="$(mktemp --suffix=.list "$(printf '%s%(%s)T%s' "${Uniquetrash:-/tmp}/xinput-" -1 "-XXXX")")" xinput > "$Unique" [ "$1" != quiet ] && cat "$Unique" || Printing=":" Xinput=":" … which lists all the devices and their parameters when run without arguments. Matrix="X 0 0 0 X 0 0 0 1" Devicetype="pointer" Device="Logitech M325" # purple wireless Id="$(grep "$Device[[:space:]]*id.*$Devicetype" "$Unique" | sed 's/^[^=]\+=//;s/\t.*//;')" [ -n "$Id" ] && "$Printing" '\nXID %2s %s ' "$Id" "$Devicetype" && "$Xinput" --list-props "$Id" && xinput --set-prop "$Id" "Coordinate Transformation Matrix" ${Matrix//X/.3} && xinput --set-prop "$Id" "libinput Middle Emulation Enabled" 1 … this last paragraph is repeated for each different pointer device. Note that some devices appear as both a pointer and a keyboard. I would imagine that the Matrix can transform the axes in any way required. I just use it to tame the wild sensitivities of most mice. Devicetype="keyboard" Device="AT Translated Set 2 keyboard" # IBM model M, PS/2 plug, GB layout Id="$(grep "$Device[[:space:]]*id.*$Devicetype" "$Unique" | sed 's/^[^=]\+=//;s/\t.*//;')" [ -n "$Id" ] && "$Printing" '\nXID %2s %s ' "$Id" "$Devicetype" && "$Xinput" --list-props "$Id" && setxkbmap gb -device "$Id" … again, repeated. The reason it's in ~/bin/ is so that you can call it anytime to examine the properties. More importantly, devices like mice can lose the sensitivity settings when X blanks the screen, or require setting when you plug in a new one. I have fvwm set up to execute the script (quietly) with a Ctrl-Alt-Shift-/ keystroke. Cheers, David.
