I had a similar problem where the player would immediately shutdown before displaying anything. it didn’t like something about one of the layouts I was displaying but crashed without an error before it could download a new scheduled layout.
I resolved it by scheduling a basic layout for that display , a static picture, . going into my local library folder on my linux player and deleting any .xlf files I could find and then launching the client, which would then force a client download.
my local library folder was /home/xibo/snap/xibo-player/common/resources the folder under home will change depending on the name of the user you are using to run the linux xibo client.
i’ll log specifics of the problem with my layout in a seperate forum post.
Hope the above helps.
