<pre>Hello, after #103572 fixed the overall Magic Trackad sensitivity regression
introduced in libintput 1.9, the patch does not fully restore the previous
level of sensitivity.
Most of the time, cursor movement works reliable but scrolling is still a hit
or miss. I have rather small fingers and soft skin and thought the new touch
range of 60:40 must be set too high (see #103572).
I have followed the instructions in <a href="show_bug.cgi?id=105696#c22">comment 22</a> to alter the value to 20:10, and
now "sudo udevadm test /sys/class/input/event21" reports
"LIBINPUT_ATTR_TOUCH_SIZE_RANGE=20:10". But this did not fix the scrolling
problem (maybe a tiny bit better than before but this might be an illusion).
Sometimes, I need to really put pressure on the trackpad to start scrolling.
It’s really annoying and I can’t remember this device being so insensitive to
simple scroll gestures in Linux since I have bought it in 2011.
To illustrate this, I have recorded a video (pardon the upright format but in
this case it actually makes sense): <a href="https://youtu.be/s-qtTzMP5HA">https://youtu.be/s-qtTzMP5HA</a>
Interestingly, gestures with more fingers seem to work more reliably (Kwin
effects triggered by libinput-gestures).</pre>
