With evtest you can see that you need to use PRODUCT_PID=0005.
Run again this 2 commands and post what you get (again).
systemctl stop kodi
ts_calibrate.shAfter kodi is stopped you can run evtest again and only press short time on top/left, top/right, bottom/right, bottom/left and in center. Maybe I see how this screen works from the output.
If you have time you can come to irc so we can talk more directly.
This addon can be installed from repository or it can be included directly in image (I'm doing this for my images). That's why there is a check if addon exists in /usr. This part is ok.
But what is not ok is that touchscreen device is not found. You can see empty touchscreen device:. Seems you don't use correct vid or pid.
Can you run this commands and post al 3 url's you get?
pastebinit /sys/class/hidraw/hidraw*/device/uevent
dmesg | pastebinit
lsusb -vv | pastebinitI forgot how waveshare screens work...
Let's start again:
1.) do you see background image when you try to calibrate from kodi?
2.) does kodi itself displays over whole screen?
3.) can you calibrate from console when run this?
systemctl stop kodi
ts_calibrate.sh
systemctl start kodi
I don't have rpi and/or waveshare display and newer had direct contact with it.
Calibration mus be done from kodi.
If you want to run from console then use ts_calibrate command.
And what is your display resolution?
maybe you could provied also a kodi 16.1 with this kernel?
What is wrong with 3.14?
In picture above I see 6.6 GB in size and 2.5 MB used. This means the card got resized.
Maybe I don't understand what exactly is your problem?
Just make SD card with LibreELEC USB-SD Creator and put SD card into your RPi. On first boot second (storage) partition will be resized and will be using all available space. No need to to anything manually.
Should the 4.8 kernel images work finer for the ones that have problems with the black screen?Do you know any kind of feedback from me if those don't work?
I don't have such tv with black screen. Happy to send shipping address for one 
Working/non-working feedback would be nice.
Not yet tested but should work.
LibreELEC-imx6.arm-7.95.1-sr-3.14.img.gz
test images with kernel 4.8
Maybe I will rebuild it when have a chance. But currently I'm out of time even for stuff I should do.
You can read here about how the calibration file is created.
And if you don't get crosshairs on whole screen try to set value to TSLIB_RES_X/Y in file /storage/.kodi/addons/config/ts_env.sh file or something like that.
How easy would it be to add the touchscreen skin touchy back into Kodi?
Should be very easy: just look for it in LibreELEC addons.
Why do you want to set pointercal file manually? The whole point of calibration process is to create this file 
You need to install tvheadend or vdr addon. IPTV Simple addon is only for iptv - not dvb.
I see lcdd addon is available from repository. Not really sure what went wrong with your (and mine) build. Building again to see if something come up.
[hr]
I made completely fresh build and this time addon was build fine.
Fakeroot is build directly from scripts/image like some other packages too: LibreELEC.tv/image at master · LibreELEC/LibreELEC.tv · GitHub
Wondering why you get this error.
Try making image first and then create addon.
And seems lcdd doesn't build for imx6:
build.LibreELEC-imx6.arm-7.95.1/toolchain/armv7a-libreelec-linux-gnueabi/sysroot/usr/include/lirc/curl_poll.h:36:29: error: array type has incomplete element type 'struct pollfd'
int curl_poll(struct pollfd ufds, unsigned int nfds, int timeout_ms);As a workaround you need to add line
CFLAGS="$CFLAGS -DHAVE_SYS_POLL_H=1"
to file packages/addons/service/lcdd/patches before PKG_CONFIGURE_OPTS_TARGET.
Any comments?
You should mentioned on which system you are building. On Ubuntu 16.04.1 LTS there is no such issues.
I suppose you'll make a PR to bump e2fsprogs?
Already done. But will be available only in LibreELEC v9 - just in case. We don't want to break something so late in v8.
