This tablet runs Windows 10 by default, but I installed Lubuntu 18.04. I' m trying to use this question as a guide but my case is different.
ELAN device is for a touchpad and every command don ' t return anything indeed. The command
sudo dmesg | grep i2c returns:

I discovered that the Mediacom drivers are the same as those for TrekStor, a company that also works with Mediacom, and found this wonderful project on github. Mediacom WinpadW700 corresponds at SurfTab wintron 7.0 (ST70416-6).
The project is about tablets and Ubuntu and states:
This repository contains firmware images for the Silead touchscreen controllers in various tablet (and other) devices [. . .]
The firmware files were extracted from Android and Windows device drivers, as published by device manufacturers. They are intended for people who prefer to replace the shipped operating system with a generic Linux distribution such as Debian or Ubuntu.
I think that I should use the
silead_ts.fw file (that is the firmware for
gslx680-acpi obtained from the
firmware.fw that is the firmware extracted from the original drivers).
silead_ts.fw firmware is especially designed for my problem. How can I use it? This section from https://github.com/onitake/gsl-firmware#silead_ts should explain how do it:
i must edit the
drivers/platform/x86/silead_dmi.c file in the source code. Then recompiling the kernel (with that file), and somewhere add the firmware which i referred in the modified file.
How can i recompile the kernel? I' m trying this guide.
apt-get source linux-headers-4.15.0-33-generic and got the
linux-4.15 folder of 800 MB. That has the path
drivers/platform/x86/silead_dmi.c in which i already made the
drivers/platform/x86/silead_dmi.c file. Following the guide i used
apt-get source linux-image-$(uname -r) and got the
linux-signed-4.15.0 folder of 118 kB.
fakeroot debian/rules editconfigs I get an error:
dh editconfigs dh: Unknown sequence editconfigs (choose from: binary binary-arch binary-indep build build-arch build-indep clean install install-arch install-indep) debian/rules:35: recipe for target 'editconfigs' failed make: *** [editconfigs] Error 2
How can I fix this error and recompile the kernel?
sudo acpidump | grep -C3 ELANyou can try
sudo acpidump | grep -C3 -i ELANto filter on
Elanas well. The same holds true for your
dmesg | grep elanuse
dmesg | grep -i elaninstead. Also could you include the output from
xinput --listin your question? I'd like to see if there is an entry for
ELAN Touchscreen idthere.
