xinput list props
Description of problem:
The touchscreen works however the horizontal movement is inverted (x axis). The vertical movement is ok.
Looking at the driver code "https://github.com/torvalds/linux/blob/master/drivers/input/touchscreen/goodix.c" I see a Boolean "inverted_x" so fixing the issue seems to be an easy thing but I have no idea how to do it.
Touchscreen is Goodix Capacitive TouchScreen (attached the xinput list-props output)
Tablet is Cube iWork10 (Chinese brand) with Intel Atom cpu
This looks like a kernel bug then.
Could you attach your current dmesg (after a fresh boot) and the output of acpidump (as root)? This way I might be able to check if it's easy or not to change that.
I think I'll also need to have your dmidecode information to be able to create a kernel patch for you.

Is there a list of devices that the kernel checks to see if it should invert or not? or is it more complicated than that?

That's basically what I need to do in the driver. Add such a list and put your tablet in it, There doesn't seem to be anything useful in the acpidump that would tell us how the device is installed, so a dmi_match should be our be solution.
*********** MASS BUG UPDATE **************
We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 24 kernel bugs.
Fedora 24 has now been rebased to 4.7.4-200.fc24. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.
If you have moved on to Fedora 25, and are still experiencing this issue, please change the version to Fedora 25.
If you experience different issues, please open a new bug report for those.
The same problem still exits in F25 and also F26 beta
fwiw, this is the matrix to intvert the x axis, as a workaround until the kernel fix is in:
xinput set-prop "ELAN Touchscreen" "libinput Calibration Matrix" -1 0 1 0 1 0 0 0 1
replace the device name with yours, and make it an xorg.conf.d snippet for it to be persistent
This is still an issue on the latest kernel (4.14.13) on Fedora 27, with the same tablet.
There is already a quirk in the goodix driver; perhaps another one should be added?
This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26
is no longer maintained, which means that it will not receive any
further security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
