Title:
ELAN Touchpad not working on Lenovo Thinkbook with Ubuntu 18.04 and
19.10
Status in linux package in Ubuntu:
Confirmed
Bug description:
I bought a Lenovo Thinkbook (Intel i5 10th generation) Model- 20RV00BNIH just
last week. I bought a DOS machine and put ubuntu 18.04 on it, the touchpad
hasnt been working ever since.
I checked with Win 10, and the touchpad works, so it is not a hardware issue.
Then I upgraded to ubuntu 19.10.
Kernel is 5.3.0-26-generic #28-Ubuntu SMP
Lots of posts on ubuntuforums indicate that 18.10 onwards should fix
this issue. They also claim that Kernel 4.18 onwards should fix this
issue, but looks like they dont, at least for me.
I tried the following. Did not help.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1825996
edit /etc/modprobe.d/blacklist.conf
add "blacklist i2c_i801" in the blacklist.conf
sudo update-initramfs -u
reboot
When I do a sudo acpidump | grep -C3 ELAN, I get the following
