I'm using two touchscreens with a Pi 4, so have this script to map the USB interfaces with the displays:

xinput map-to-output 8 HDMI-1
xinput map-to-output 7 HDMI-2

This works great, until I put it into `/home/pi/.config/lxsession/LXDE-pi/autostart`, but then it just boots to blank screens.

I've tried inserting a `sleep` in case it wasn't ready to do it, and also I have tried prefixing with `@`

Code: Select all

@sleep 60
@xinput map-to-output 8 HDMI-1
@xinput map-to-output 7 HDMI-2

but neither made a difference, and also calling it as a script like

Code: Select all

@. /home/pi/mapdisplays

...but still nothing. What am I doing wrong?

So, do I understand correctly:

a graphical login hangs as soon as you add these commands
without these commands the graphical login does not hang
the commands work fine executed by themselves

???

You can always try appending an ampersand to each command, like so:

Code: Select all

xinput map-to-output 8 HDMI-1 &
xinput map-to-output 7 HDMI-2 &

although I don't think this is what's causing this error.

Please define "hangs" - What _exactly_ happens? Anything in the logs?
Show us a part of

Code: Select all

journalctl -b

for the relevant timespan.
