Bug ID: 359460
Summary: Synaptic touchpad wrong settings and limits
Product: Touchpad-KCM
Version: unspecified
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: daemon
Assignee: rajeeshknamb...@gmail.com
Reporter: w01dn...@gmail.com
On start kcm touchpad sets some wrong setting which leads to scrolling
problems.
Default parameters value:
MaxTapMove = 234
VertScrollDelta = 106
HorizScrollDelta = 106
CircScrollDelta = 0.1
Set on start:
MaxTapMove = 20
VertScrollDelta = 10
HorizScrollDelta = 10
CircScrollDelta = 6
That parameters leads to very strange touchpad scroll (very big scroll values,
hangs of input after using touchpad scroll). I think values MaxTapMove,
VertScrollDelta, HorizScrollDelta should be multiplied by some coefficient
(10?) of relation between UI units and device one, e.g. when I set
VertScrollDelta = 9.8mm in kcm_touchpad I've got same 10 from synclient.
And/or upper limit should be changed. For CircScrollDelta I can't set default
0.1 value.
Reproducible: Always
Steps to Reproduce:
1. Use synaptic touchpad.
2. Start KDE Plasma 5.
3. synclient -l > kde_params.txt
4. Log off/in to other DE/WM (IceWM, LXQt)
5. synclient -l > def_params.txt
6. Compare.
Actual Results:
UI units (mm) are just written to touchpad settings. Default touchpad values
coudn't be set using UI. Plasma 5 touchpad settings leads to input problems
(several scrolls make system unresponsible to input).
Expected Results:
Correct UI mm to device units coversion and/or upper limit correction.
openSUSE Leap 42.1, x86_64, Plasma 5 (RPMs from git using
KDE:Unstable:Frameworks).
