Hello guys!
I have one script, which rotate screen with wacom device counterclockwise.
On my X200t I bind this one to rotate-key on Windows (under display). So, I think it must be usefull in tablet mode.
Can anyone test it and give feedback plz?

Thanks =)

Makes sense to me. However, I've never used Wacom stylus. Nevertheless, I decided to reply and complicate your life

I don't know about x220t, but on my x220 I have succesfully tested a following script to autorotate the xrandr screen when the accelerometer says so:

Code: Select all

#!/bin/bash
#Adaptex from x220 tablet using Arch wiki (https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_X200https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_X200)
#2015/12/01 (changes: set to x only for now, update xrandr syntax, dump rotate function)

while true; do
    # 1) We extract data about the actual position
    position=$(cat /sys/devices/platform/hdaps/position)
    x=$(echo $position | sed -n "s/(\([-0-9]*\),\([-0-9]*\).*)/\1/p") # most of time contained in [350,650]
    y=$(echo $position | sed -n "s/(\([-0-9]*\),\([-0-9]*\).*)/\2/p") # most of time contained in [-650,-350]

    # 2) We work out the x value (= left and right inclination) (always between

    if [ $x -lt 400 ]; then
        xrandr --output LVDS1 --rotate right
    elif [ $x -gt 600 ]; then
        xrandr --output LVDS1 --rotate left
    else
        xrandr --output LVDS1 --rotate normal
    fi

    # #3) We work out the y value (= front and back inclination)
    #    if [ $y -gt -400 ]; then
    #      xrandr --output LVDS1 --rotate inverted
    #    elif [ $y -lt -600 ]; then
    #        xrandr --output LVDS1 --rotate normal
    #    fi

       # 4) wait before checking the value again
       sleep 0.5
     done

I presume you could play with that:) As you can see, /sys/devices/platform/hdaps/position is the place to go for the laptop orientation coordinates.
That is of course if the hdaps module is loaded in the kernel!
Coming back to your script, I should probably follow your example and put 'case' instructions, always safer than nested ifs...
best regards:)

Hi!
Yeah, I saw some of autorotate scripts (even may be on Archwiki), but it useless for me for one reason :
it can't correct position when I lying on back =)
Such as other touchscreen device.
May be its possible to find value that comfortable for me.
I'll try this one, thnx!

cheers, Ivan.

P.S. Yes, I've HDAPS, it's cool.
I don't use this sensor for HDD, because SSD in my laptop, but it really interesting play neverball or Tuxkart via accelerometer =)
