Hi fellow Neon users,

I'm having Bluetooth inactivity timeout issues on input devices - Keyboard and Mice. Keyboard is Logitech K780 and mice are Logitech M585 and HP X40000b - I tried a non-logitech device in case it was a logitech issue. The devices time out after a short period of inactivity, perhaps 30 seconds, and take time to wake up again, meaning that the keyboard misses at least the first character typed, and the mouse has to be moved for 2 -3 seconds before the cursor start following it. This makes them unusable, especially when typing in a password, if the first character is missing. I've tried changing the settings in /etc/bluetooth - in input.conf and main.conf - and restarting the bluetooth service and also rebooting but nothing changes. The most common suggestion is to set IdleTimeout=0, but that hasn't worked.

Does anyone have additional wisdom to share, or debugging steps to try?


I'm on ....

I'm having the same issue with a bluetooth keyboard - started after upgrading from 18.x to 20.04. It's extremely annoying: often after reading some webpage for 5 min when I use only a wireless mouse and I go back to typing something, it takes 5s for the keyboard to wake up.

I have the same issue. After upgrading to 20.04, bluetooth keyboard idle timeout is too fast. Worked fine in 19.10. I tried to set IdleTimeout to 0 in /etc/bluetooth/input.conf, and also tried to create a udev rule to prevent the timeout. No luck. Keyboard times out quickly, after 30 secs or so, and then takes time to wake up. Any suggestions would be great, it's pretty annoying.

Hello,

I also have the exact same issue for mouse and keyboard... I have to switch to a USB keyboard for now since "unusable" is a quite a good term to describe the problem.

Also tried to set the timeout to 0 in /etc/bluetooth/input.conf but nothing changes.

Thanks
