SUMMARY Setting touch mode to automatic results in it being always disabled since 6.3.0. Automatic orientation no longer works when restricted to tablet mode and UI elements no longer increase in size when disconnecting the "pointer" device (mouse or touchpad). STEPS TO REPRODUCE 1. Set touch mode to "automatically enable as needed" 2. Have a device with a touchscreen, but no mouse or touchpad 3. Query org.kde.KWin.TabletModeManager tabletMode property on D-Bus, it always returns false 4. Unload the buttonrebinds plugin (e.g. using D-Bus) 5. tabletMode should return true OBSERVED RESULT tabletMode always is false and display orientation as well as UI elements stay in non touch mode. Once the buttonrebinds plugin is unloaded, everything works as expected. EXPECTED RESULT tabletMode returns true once mouse and touchpad are disconnected, even if the buttonrebinds plugin is loaded. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.3.0 KDE Frameworks Version: 6.10.0 Qt Version: 6.8.2 Kernel Version: 6.13.2-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Core™ i7-7500U CPU @ 2.70GHz Memory: 7.5 GiB of RAM Graphics Processor: Intel® HD Graphics 620 Manufacturer: Acer Product Name: Switch SW512-52 System Version: V1.08 ADDITIONAL INFORMATION The buttonrebinds device now counts as a pointer device in 6.3.0, but is not ignored by shouldIgnoreDevice in tabletmodemanager.cpp. My device specifically has no built-in tablet mode switch and instead relies on the cover keyboard (which contains a touchpad) physically disconnecting, meaning kwin used to switch based on any pointer device existing.

Prevent virtual input devices from blocking tablet mode Let only physical input devices block the tablet mode. If more input devices need to block the tablet mode, we can look into adding generic tags in the InputDevice.
