I just start using elementary os 5.0 juno today and after installiation, system showed update notifications. After 13 programs updated, i opened a video and there is no display but video continued and there is sound. I tried different programs after that, same result. What should i do now? I can play videos from youtube. But i can not play files .mkv .mp4 etc.
Could it be a problem of Nvidia video card?
Thank you.
