SUMMARY When resuming work on my laptop after sleep / closing the lid, sometimes the touchpad is unrensponsive and requires two fingers to move the pointer. STEPS TO REPRODUCE 1. Work with your laptop normally 2. Close the lid 3. Open the lid 4. Go through 1-2-3 a few times until the problem appears. OBSERVED RESULT The touchpad does not respond to the usual one-finger operation, while using two fingers can move the cursor. EXPECTED RESULT The touchpad works normally. SOFTWARE/OS VERSIONS Operating System: Fedora Linux 40 KDE Plasma Version: 6.1.0 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.1 Kernel Version: 6.9.5-200.fc40.x86_64 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i5-8250U CPU @ 1.60GHz Memory: 15.5 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 Manufacturer: Dell Inc. Product Name: Latitude 7490 ADDITIONAL INFORMATION I observed this behaviour on the GNOME Session as well, but I never experienced on Plasma X11. This could point to an upstream issue (Wayland). Switching to a virtual terminal and then back to the desktop fixes the issue. Similar issues have been reported in the past 2+ years across several platforms: https://askubuntu.com/questions/1387034/touchpad-starts-requiring-2-fingers-way-to-fix
