After suspend stylus position confused about rotated screen in multi-monitor setup

[Rob Frohne]

I have a tablet computer that has the monitor rotated to upside down landscape position. There is also an external monitor connected to this computer. When I suspend and awake this computer, the stylus position is as if the tablet computer's screen was not rotated. The mouse cursor is fine, but not the stylus, and the confusion of the stylus goes into the external monitor.

Thanks for all you do to fix annoying bugs for all of us users!

A work around is to rotate the screen, as the stylus regains its bearings when you do that.

This kept bothering me so I came up with a work-around. I put the following file (with chmod 755 so it could be executed) in /etc/pm/sleep.d/ and called it 20_map-to-display. You have to use the xinput and xrandr commands to determine what your display is called (where I have LVDS-1) and which input devices are not mapped properly (numbers to put in where I have 13, 14, and 16), and modify those parameters. I think I also had to install pm-utils with apt.

PATH=/sbin:/usr/sbin:/bin:/usr/bin

case "${1}" in
        resume|thaw)
                sleep 5
                xinput map-to-output 13 LVDS-1
                xinput map-to-output 14 LVDS-1
                xinput map-to-output 16 LVDS-1
;;

I hope this helps anyone else with my particular problem.

Unfortunately the above work-around only works when I suspend using pm-suspend. The system is using systems. I'm working on figuring that out now.

[Rob Frohne (frohro)]

Okay, so here is the new work-around. You put this file in /usr/lib/systemd/system-sleep/
I called it 20_map-to-display. Call it what you like. It needs to be executable.

#!/bin/sh
export HOME=/home/frohro/
export DISPLAY=:0

case $1/$2 in
        post/*)
                /usr/bin/su frohro -c "/usr/bin/sleep 3;/usr/bin/xinput map-to-output 13 LVDS-1"
                /usr/bin/su frohro -c "/usr/bin/sleep 3;/usr/bin/xinput map-to-output 14 LVDS-1"
                /usr/bin/su frohro -c "/usr/bin/sleep 3;/usr/bin/xinput map-to-output 16 LVDS-1"
;;
esac

I hope this is useful to someone else.
