Comment 60 for bug 1816947

Any solution pending on this? I have same fault - as expected I guess.
Have just rebuilt PC from old Ubuntu 16.04LTS to 18.04LTS and Trackpad has developed same problem.
Confirming I'm on DELL XPS13 L321X
 - Trackpad only works sporadically, short distances, if very light touch and moving slowly++
 - Cannot click and drag anything
 - Cannot highlight text
PS: I'm virtually coding illiterate but will do whatever I can to assist if needed
Is there something I can download and overwrite as a fix?
If so, please spell out coding syntax required to complete
Cheers guys. (Linux noob)
