End of last year I have replaced my aging ASUS Zenbook UX32LN with a Ryzen-based UM431DA. After installing Ubuntu 20.04 focal with kernel 5.4 I have noticed four annoying problems:
- Initializing X.Org and getting to the login screen may not work
- Suspend does not work (system freezes)
- There is disturbing tearing when moving windows or playing movies
- Sound is very loud and volume control does not work properly
