<pre>Hi,
Thanks for the recordings, the precision of the touchpad seems to be excellent
with both gestures.
Can you try changing these lines in libinput/src/evdev-mt-touchpad-gestures.c
(around line 200):
/*
* Semi-mt touchpads have somewhat inaccurate coordinates when
* 2 fingers are down, so use a slightly larger threshold.
*/
if (tp->semi_mt)
move_threshold = TP_MM_TO_DPI_NORMALIZED(4);
else
move_threshold = TP_MM_TO_DPI_NORMALIZED(2);
To:
move_threshold = TP_MM_TO_DPI_NORMALIZED(2);
Then re-build libinput, install the new version and see if that solves your 2fg
scrolling problems?
Regards,
Hans</pre>
