Bug ID: 404934 Summary: Keyboard modifiers cause touchpad disable to get stuck Product: Touchpad-KCM Version: unspecified Platform: Ubuntu Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: daemon Assignee: rajeeshknamb...@gmail.com Reporter: spa...@gmail.com Target Milestone: --- SUMMARY Intermittently (a few times per day) my system enters a state where using modifier keys (shift, alt, control, super) results in the touchpad staying disabled when it should be disabled for just 250ms or not at all. The precise behavior is not always predictable, but at least one such mode comes up repeatedly. STEPS TO REPRODUCE 1. unknown requirements to enter the problematic mode 2. press and release Alt key 3. press and hold Alt key 4. release after a few seconds. OBSERVED RESULT Press and release causes the touchpad to disable for the configured delay, 250ms by default. Press and hold causes the touchpad to disable for the configured delay, then re-enable after the delay while the key is still held. Release causes the touchpad to disable indefinitely, until Alt is tapped again. EXPECTED RESULT As in normal usage, no part of modifier/shortcut usage should trigger the touchpad disabling behavior. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 19.04 KDE Plasma Version: 5.14.90 KDE Frameworks Version: 5.54.0 Qt Version: 5.11.3 ADDITIONAL INFORMATION This is probably a duplicate of #332654 from five years ago. I have run xev while the problem is extant and it registers all the keyboard events that I expect for pressing and holding and releasing the key, and no touchpad events when the touchpad is disabled. -- You are receiving this mail because: You are watching all bug changes.
