[Feature Request] Rotate input

[FunctionalHacker]

I have a 2-in-1 laptop and sometimes I like to rotate the screen 90 degrees and read PDF's and the like. Back in X, I used to be able to do this: xrandr --output eDP --rotate right && xinput set-prop "ELAN Touchscreen" --type=float "Coordinate Transformation Matrix" 0 1 0 -1 0 1 0 0 1

I can do the first part of the command, the rotating of the screen in Sway, but the second part, which is rotating the input of the touch screen I did not find in the documentation, so I think this is not implement yet.

Can you try mapping the touch screen to the output?

[FunctionalHacker]

How does one do that? Sorry, I'm very new to Sway

[emersion]

You can have a look at the manpage: man 5 sway-input. Grep for "map". ;)

That worked a treat! Thank you very much and sorry for wasting your time. I will check the man pages more thoroughly next time 😄

Thanks for the hint, @emersion! 👍

This worked for me:

swaymsg input <my-touch-screen> map_to_output <my-monitor>

To get input and output devices, I did swaymsg -t get_inputs and swaymsg -t get_outputs respectively.

On my Lenovo X220 tablet, this ended up being

swaymsg input 1386:230:Wacom_ISDv4_E6_Pen map_to_output LVDS-1

After that, I flipped the screen using

swaymsg output LVDS-1 transform 180

and positioning the cursor on the screen with a finger or the stylus worked flawlessly.

Thanks @emersion for the hint and @mb720 for giving exact commands, they worked perfect.
Just to comment that mouses (and maybe pointers) remap automatically after screen rotation.

I have this config file

# Read `man 5 sway` for a complete reference.

set $logo Mod4
set $alt Mod1

output HDMI-A-1 {
	resolution 1024x600
	bg ~/rvs.jpg fill #000000
}

input "6790:58851:TeNizo_TeNizo_R7Series_TC" {
	map_to_output HDMI-A-1
}

output HDMI-A-1 transform 90

bindsym $logo+Return exec foot
bindsym $logo+Shift+q kill
bindsym $logo+Shift+c reload
bindsym $logo+Shift+e exec swaynag -t warning -m 'You pressed the exit shortcut. Do you really want to exit sway? This will end your Wayland session.' -B 'Yes, exit sway' 'swaymsg exit'

the touchscreen is a cheapo 7in hdmi module from ali. input is flipped both horizontally and vertically.
