Touchpad of Yoda2 doesn't work well via PS/2 mode, most time the data is
lost sync via PS/2.
I have made a patch in upstream/Ubuntu 4.15/4.13 kernels to force
touchpad using SMBus mode.
SMBus mode requires i2c-i801 kernel module which is in modprobe
blacklist in Ubuntu 18.04/16.04. User has to remove i2c-i801 manually.
i2c-i801 in blacklist is a very old workaround to fix HP compaq nc6000
(Bug #10306), this module should be removed from blacklist. |

SRU justification
============
[Impact]
Many modern notebooks need i2c-i801 kernel module to function, but it is blacklisted by /etc/modprobe/blacklist.conf, which gives a very poor user experience.
[Test case]
1. Install Ubuntu
2. Check touchpad works or not
3. Install the fixed kmod package
4. Confirm touchpad works
[Regression Potential]
i2c-i801 was blacklisted due to bug 16602. The user complains an HP Compaq nc6000 notebook cannot suspend without blacklisting i2c-i801. While this is a way to workaround the suspend issue, the proper fix should be in linux kernel. Since nc6000 was a machine sold in 2004, it is too difficult to find someone to verify if it will regress due to this SRU. The rationale to blacklist it is: https://bugs.launchpad.net/ubuntu/+source/hotplug/+bug/16602/comments/5, however it is no longer valid nowadays on modern computers.
Besides, there look like to be a quirk in linux kernel that fixes it:
https://github.com/torvalds/linux/blame/master/drivers/pci/quirks.c#L1434
