SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Log into KDE plasma (I am using the wayland session, but I don't think it's different on X11) 2. Try using the touchpad OBSERVED RESULT Touchpad sometimes does not work. By navigating to the settings, it is apparent that the touchpad is diabled. It can be re-enabled. Trying to re-enable the touchpad using the keyboard macro button does not work. EXPECTED RESULT The toucpad should work normally and should never be disabled without the user requesting it. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: KDE Plasma 5.27.6 on Archlinux (available in About System) KDE Plasma Version: 5.27.6 KDE Frameworks Version: 5.107.0 Qt Version: 5.15.10 ADDITIONAL INFORMATION I am using a convertible laptop with a touchscreen. When converting it to tablet mode, the touchpad is automatically disabled (as it should be). This interaction might be causing the problem, I have no means of testing this as I only have this laptop.
I can now confirm that it happens on every boot. The settings show a connected mouse, which might disable the touchpad? There is no mouse connected.
After re-enabling the touchpad in System Settings, when you flip your laptop into tablet mode, does the "enabled" checkbox get unchecked in System Settings? or does it remain checked despite te touchpad being (correctly) disabled while in tablet mode?

Yes, the checkbox correctly gets unchecked. Only after I close the system settings and open them again though.
Thanks.
Ok, so something is disabling the touchpad intentionally. Any chance you could try this on X11 and see if it's working as expected there? Thanks!

Recently installed Plasma again on the laptop where the bug originally happened. Deleting all KDE related config files seems to have resolved the issue, maybe that can help identify what went wrong in the first place?
Unfortunately not, since if you deleted the config files, that means anything we could examine to figure out the issue is also gone. Glad it's fixed now.
The problem is back after some usage time. Please tell me which config files could be responsible for this so I can submit them here.
I wonder if the fix for Bug 486763 might have fixed this. Can you test again in Plasma 6.1.5 or later? Thanks a lot!
Unfortunately, I cannot. The laptop on which this problem occured broke.
Ok, does that mean you can't reproduce the issue anymore with the laptop's replacement?
I will be more precise: the laptop's screen broke and now the touchscreen does not work anymore. Ever since this happened, the issue has been gone.
In that case there's probably nothing to be done here. It may have even been a hardware or firmware issue. Do let us know if it happens again, and we can re-open this bug report. Thanks a lot!
