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 33230: 0F 00 03 04 49 4E 54 31 70 0A 20 49 44 41 44 A4 ....INT1p.
