https://askubuntu.com/questions/1300689/problem-with-usb-keyboard-and-
mouse-on-raspberry-pi-4b-with-ubuntu-20-10
My system:
Linux myRaspi 5.8.0-1010-raspi #13-Ubuntu SMP PREEMPT Wed Dec 9 17:14:07 UTC
2020 aarch64 aarch64 aarch64 GNU/Linux
I'm using
- Raspberry Pi4B 8GB
- Logitech MK120 Keyboard and Mouse (wired).
How I could reproduce the mentioned crash:
- Boot and wait (don't touch mouse/keyboard) at login-screen for five minutes
- After five minutes, screen will turn black
- If you move the mouse then, screen will be back again but frozen
(mouse/keyboard not working). x server will be crashed.
restarting x-server via ssh or via Alt+SysRq+k is possible
