Bug ID: 496943
Summary: Touchpad becomes sluggish/choppy on restart and sleep
Classification: Plasma
Product: kwin
Version: 6.2.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: input
Assignee: kwin-bugs-n...@kde.org
Reporter: minelorderago...@gmail.com
CC: duha.b...@gmail.com
Target Milestone: ---
SUMMARY
Upon restarting or waking from sleep, the touchpad sometimes (~50% of the time)
stops functioning properly. the touchpad becomes unresponsive and laggy,
registering clicks, zooming (when it can control it), and scrolling
sporadically. Likely not a distro issue on account of reports from other
distros that i have seen, primarily fedora and arch. touchpad typically
continues functioning normally after sleeping and waking again, and often
(though not always) does the same after restarting again.
STEPS TO REPRODUCE
1. restart system or enter sleep mode
2. log back in
3. observe touchpad behavior
4. if touchpad behaving as described, restart or sleep again
5. verify return to normal behavior
OBSERVED RESULT
EXPECTED RESULT
on some attempts the touchpad will become unresponsive and trigger inputs
seemingly at random.
