Lea Lange: A) The observation of the touchpad working after one cold boot doesn't confirm it is not a kernel issue. Also, your touchpad is recognized as an Elantech as documented in: https://www.kernel.org/doc/html/latest/input/devices/elantech.html
B) Was there ever a time where the touchpad consisently worked after booting? If so, what release specifically? C) To clarify, after a boot where the touchpad isn't working, does rebooting consistently make it begin working? D) In order to allow additional upstream mainline kernel developers to examine the issue, at your earliest convenience, could you please test the latest mainline kernel? Please keep in mind the following: 1) The one to test is in a folder at the very top of the page (not the daily folder). 2) The release names are irrelevant. 3) The folder time stamps aren't indicative of when the kernel actually was released upstream. 4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . If testing on your main install would be inconvenient, one may: 1) Install Ubuntu to a different partition and then test this there. 2) Backup, or clone the primary install. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the mainline kernel, please comment on which kernel version specifically you tested. If this issue is not reproducible in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the Bug Description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists. If the issue is reproducible with the mainline kernel, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Also, you don't need to apport-collect further unless specifically requested to do so. It is most helpful that after testing of the latest mainline kernel is complete, you mark this report Status Confirmed. Lastly, to keep this issue relevant to upstream, please continue to test the latest mainline kernel as it becomes available.

So far reboot helped. Now under Ubuntu 16.04 it just stopped working after reboot. As far as I can recall I did apt-get upgrade before, so probably there was something in there. I decided to upgrade to Ubuntu 18.04 and see if it solves the problem. It doesn't. - synaptics is installed, but: $ synclient Couldn't find synaptics properties.
