KoBox, or how to run X.org and Firefox on your Kobo

[Elektron]

Thanks for proving it safe to run on the H2O 2v2. I was afraid to brick it

Hi,
Glad to see you got it up and running. You should see the Landscape mode hack (search "forceallowlandscape kobo" in Google) and that will probably solve all of your problems. You'll get a new landscape mode switch in your tray and you'll just have to toggle the "Landscape" mode.
Please let me know how it goes

When I turn on landscape mode, touch input in Nickel is rotated 180 degrees from the display.

I'll adjust the Python file for your problem then. You should get it by tomorrow morning here in Canada
Now I need some sleep...

Hi,
I checked my Python file and I doubt that that's the problem. Can you try starting up KoBox and then telnet/SSH your Kobo and entering this command:

echo 1 > /sys/class/graphics/fb0/rotate

even if you've already tried it? Then, tap somewhere on the screen to activate elements and you could see an update. If that doesn't work, try again with 0.5 instead of 1, and restarting your Kobo if this does nothing, then retyping the command in with the last number.
I hope it'll work for you!

I'll do it... Soon™
I'm busy, sorry!!!

Writing 1 to /sys/class/graphics/fb0/rotate does nothing, as before. Strangely, it seems that writing 3 to it sets it to 1, and puts the display in normal portrait mode (though touch input is still rotated 90 degrees counterclockwise from the display). Writing 0.5 sets it to 0 and corrupts the display.

Welcome to NTX kernels that do mirrored inversions behind your back .

And... worse.

Would be there a way to put it in the correct rotation?
(I don't remember which one, but it is one of the two landscape modes)

@Georgelemental : this might help:

#!/usr/bin/python3
import os

# Touch mapper for Xorg/XDOTool >> Kobos
file = open("evtest-log","r")
coordinates = file.read()
file.close()
# Prevent other exit status than 0 if evtest log file is empty
if len(coordinates) <= 10:
    exit()
else:
    c1 = coordinates.split("\n")

    # Mapping x
    for item in c1:
        if "ABS_MT_POSITION_X" in item:
            c2 = item.split(" ")
            c3 = c2[-1]
    x = c3
    print("registered native x " + x)

    # Mapping y
    for item in c1:
        if "ABS_MT_POSITION_Y" in item:
            c2 = item.split(" ")
            c3 = c2[-1]
    y = c3
    print("registered native y " + y)

    # Dividing for lower resolutions
    # Originally made for Kobo Libra -> 1680x1264 / 2 = 840x632
    x = float(x)
    y = float(y)
    # Nasty hack
    x2 = y
    y2 = x
    print("converted native x to %s" % x2)
    print("converted native y to %s" % y2)

    # Passing x + y to xdotool
    os.system("DISPLAY=:0 xdotool mousemove {0} {1}".format(x2, y2))
    # Clicking mouse button
    os.system("DISPLAY=:0 xdotool click 1")

    # Done! Emptying the file
    os.system("> evtest-log")

Put it in /mnt/user/root/.utils/ while KoBox is running to replace the old xorg-kobo-touch.py
and start it in normal portrait mode

@NiMa: Correct for whom? ^^.

Correct for nickel is fbdepth -R UR. Correct for a 1:1 touch:fb mapping is... not always (if ever) possible ^^.

Well OK then...
Would it be possible to make a simple C/Python/Bash/whatever script to auto-determine the rotation for each device and set it so that my touch program won't be messed up?

(it is in FBInk, isn't it?)

[NiLuJe]

You're looking at it the wrong way around.

There's *always* a translation necessary, the touch layer *never* matches the fb.
c.f., Plato's input code for an idea of how "fun" this is to handle, or my first answer on github when I hinted that this was liable to drive someone mad for some other examples).

The script almost fixes it. With normal portrait mode, mouse input is reflected across the center vertical axis from the display.

What do you mean? I didn't quite understand.
Do you still have inverted touch input? Like from when you tap the menu, it taps the desktop switcher?
