Bug ID: 406778
Summary: KCM touchpad settings ignored in X11 session with
Linux 5.0
Product: Touchpad-KCM
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm
Assignee: atulbish...@gmail.com
Reporter: nicolam...@aol.com
Target Milestone: ---
Created attachment 119564
--> https://bugs.kde.org/attachment.cgi?id=119564&action=edit
Touchpd configuration file for xorg.
SUMMARY
Since I upgraded my system to Linux 5.0 the touchpad settings from KCM are
ignored. Specifically, the tap-to-click can be set but is ignored, i.e.
tap-to-click does not work. This happens without any xorg configuration files.
If I add a configuration file /etc/X11/xorg.conf.d/30-touchpad.conf as the
attached one then tap-to-click works again, but this time it cannot be disabled
from the KCM module.
Everything works as expected with Linux 4.19.
STEPS TO REPRODUCE
1. Install Linux 5.0
2. Remove any xorg configuration file for the touchpad
3. Start Plasma
OBSERVED RESULT
The touchpad tap-to-click does not work, event when enabled from KCM.
EXPECTED RESULT
The touchpad tap-to-click behavior should comply with the KCM settings.
