Recently I bought a Lenovo IdeaPad (Intel i7 10th generation). I installed Ubuntu 16.04 on it, but at no point did the touchpad work for me! Also, initially I tried to install Ubuntu 18.04 and upgraded to the latest kernel, but not only the touchpad didn't work, also the graphics didn't work properly and I eventually decided to go back to 16.04.
I have not checked the touchpad on Windows, as I bought a DOS machine and put ubuntu on it instead.
The touchpad is not the only hardware on my laptop that's not working in ubuntu, but let's focus only on it for now.
From reading a little bit I found out that many new laptops have problems with their touchpads, mostly ElanTech hid ones. It seems to me that my problem is similar to this post: ELAN Touchpad not working on Lenovo Thinkbook with Ubuntu 18.04.
Also, from the information in this post: Lenovo IdeaPad 330 touchpad not working, it seems the problem is that the id of my ELAN touchpad is not listed in the kernel, so Ubuntu doesn't recognize it at all!
About my system:
uname -srv
gives:
Linux 4.15.0-74-generic #83~16.04.1-Ubuntu
xinput -list
gives:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech USB Optical Mouse id=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Power Button id=7 [slave keyboard (3)]
↳ Integrated Camera: Integrated C id=8 [slave keyboard (3)]
↳ Ideapad extra buttons id=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
Note that no touchpad is recognized by Ubuntu!
By running sudo acpidump | grep -C3 -i elan
I was able to find my ELAN id, which is 0633, as seen here:

Apparently this problem can be solved by recompiling the kernel with this id code included in the elan_i2c_core.c
file, but I don't want to mess with the kernel!
Is there any other way I can solve this problem?
If not, I would appreciate some help in filing a bug report.
