My current openSUSE setup is running into problems with the connected displays
via USB-C. From time to time the external monitors stop working and my keyboard
and webcam LEDs are blinking irregular.

I'm running openSUSE Leap 15.2:

Main hardware components:
- Lenovo ThinkPad T495
- Lenovo ThinkPad Dock Gen2
- 2 Dell monitors
- external keyboard and mouse
