@Durieux I am unsure this is the place for such questions, but the answers are as follows (at least for Linux Mint).
Run the package manager that is called (confusingly) Synaptics. You should be able to find it in a menu under that name or under a name such as 'package manager'. Search for and install the package 'xserver-xorg- input-libinput'. Search for and uninstall the package 'xserver-xorg- input-synaptics'. Were you to have both installed at once, one - I do not know which - would likely take precedence over the other. The worst that could happen with any of this is that you end up with no functioning driver and have to use the keyboard and/or terminal to ensure that you have one of the drivers installed. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1245328 Title: Synaptics kernel driver does not report finger width information, breaking usermode driver's palm detection Status in linux package in Ubuntu: Confirmed Bug description: While doing some work on the Xorg synaptics driver, I noticed that we never actually detect palm blocking even after running synclient PalmDetect=1. Digging in a bit, the driver claims in its capability bits that it should be sending ABS_TOOL_WIDTH records, but according to evtest(1), the driver never sends these advertised records to userspace. As a result, the Xorg synaptics driver never sees hw->fingerWidth become non-zero in SynapticsDetectFinger and never detects that I've mashed my palm into the large touchpad on this machine. Expected: Kill X. Run evtest(1). Select touchpad device. Move touchpad. See ABS_TOOL_WIDTH records in the event stream. Actual: No ABS_TOOL_WIDTH records even though the device claims to support them in its capability bits.
