Adding missing vendor model of my laptop: ASUSTeK COMPUTER INC UX305LA run sudo libinput measure touchpad-pressure please and let me know how you go with that. 10:8 may be the right value in the end, but it's best to measure it first ping? Sorry for the delay. I don't have that sub-command available on my system (Archlinux updated). In fact, I even think it's a bug because when ran, I get an error saying "Failed to execute 'touchpad-pressure' (No such file or directory)". I have "straced" the command and in fact, it looks for a non-existing file. I'm trying to remember the method I've used to measure the sensitivity but I cannot remember and can't find it on my history... I will try to check again during this week. However, if you know any other method to achieve the same, I'd appreciate your comments. you'll need a newer libinput then, 1.9 was released last week. for the command itself, you can just grab the git repo and run sudo ./tools/libinput-measure-touchpad-pressure directly, no building required. This is the output (consider that it's using the corrected values that I have applied... I would not like to intentionally break my touchpad again). However, if truly needed, just let me know Ready for recording data. Pressure range used: 8:10 Palm pressure range used: 130 Place a single finger on the touchpad to measure pressure values.

What I don't understand is why you need your hwdb override. Your device should just use 8:10 anyway - that's the generic fallback for elantech touchpads. What is it set to when you remove it?
