- RPi4 2G
Bluetooth Keyboard
Bluetooth Mouse
fully updated Arch Linux aarch64
XFCE4
LightDM
After sitting idle for a while at the XFCE4 desktop, mouse clicks and keyboard presses appear to either be ignored or not received at all. The mouse still moves the pointer, the clock continues to update the time, CTRL+ALT+[0-7] continues to function to switch between VTs, and at a VT keypresses are seen just fine, I can SSH into the unit at all times.
Any thoughts, suggestions?
