Hi there.
Did some google search and can't find any info on this strange problem that I'm having.
I'm using my Raspberry pi in my car as full headunit replacement.
For software I'm using "OpenAuto pro" that's on top of standard raspbian buster.
Everything works well, I'm using KODI for music playback and AndroidAuto for navigation and internet radio.
But the problem is that after some time (it doesn't seem to be a fixed time) all applications get closed and all I see is raspbian desktop wallpaper and login request window. And I can't login because I don't have a keyboard in my car. I do have a onscreen keyboard but It's not shown on screen.
What could be the problem?
