I opened this a couple of weeks ago, but I'm wondering if I need to to add abug with Ubuntu directly, as this hasn't been looked at in Neon. Thank you for your bug report! However this bug report was created/provided previous to 01/01/2023 and also has not received any updates since before 01/01/2025. Unfortunately KDE neon no longer provides updates for anything older than noble 24.04 based edition's. Please upgrade to KDE neon noble and if you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report. Thanks for understanding! |
SUMMARY I'm running KDE Neon 5.18 on the 5.3.0-51-generic #44~18.04.2-Ubuntu SMP kernel, and the Bluetooth subsystem inactivity timeouts for keyboards and mice is causing serious usability problems. After a short period - perhaps 60 seconds - moving the mouse doesn't cause a corresponding move of the cursor...it takes about 2 seconds before a response is seen. Mouse clicks are similarly delayed, and have been registered at the wrong screen location. For the keyboard, there is a similar delay, and sometimes the first keystroke doesn't register, which has led to mistakes inputting passwords, and erroneous data entry. I've changed the settings in /etc/bluetooth/input.conf and main.conf, but nothing changes the problem. The devices are a logitech keyboard, model K780, a logitech mouse M585 and an HP mouse X4000b. This has been a persistent problem ever since I built this machine. As it's so pervasive, I've stopped using Bluetooth completely. Machine details....
