Also a try to compose a udev rule with:
sudo touchpad-edge-detector 106x78 /dev/input/event10
Touchpad ELAN0501:00 04F3:300B Touchpad on /dev/input/event10
Move one finger around the touchpad to detect the actual edges
Kernel says: x [0..3239], y [0..2347]
Touchpad sends: x [0..3239], y [0..2347] --- \
Touchpad sends: x [0..3239], y [0..2347] /^C
Touchpad size as listed by the kernel: 104x73mm
User-specified touchpad size: 106x78mm
Calculated ranges: 3239/2347
Suggested udev rule:
# Acer Aspire E5-574
evdev:name:ELAN0501:00 04F3:300B
Touchpad:dmi:bvnInsydeCorp.:bvrV1.18:bd05/25/2017:svnAcer:pnAspireE5-574G:pvrVvrChassisVersion:*

EVDEV_ABS_01=0:2347:30
EVDEV_ABS_35=0:3239:31
EVDEV_ABS_36=0:2347:30
edited to a file:
/etc/udev/hwdb.d$ cat acer.hwdb
# Acer Aspire E5-574
evdev:name:ELAN0501:00 04F3:300B
Touchpad:dmi:bvnInsydeCorp.:bvrV1.18:bd05/25/2017:svnAcer:pnAspireE5-574G:pvrVvrChassisVersion:*

EVDEV_ABS_01=0:2347:30
EVDEV_ABS_35=0:3239:31
EVDEV_ABS_36=0:2347:30
and updating the hwdb with the command:
systemd-hwdb update
After this change not even the mouse buttons works.
May you have any suggestions what I can do to fix this problem?
Best regards
Alexander
