Video window window shows nothing

On my Linux system I can start Davinci Resolve. When I add a video to my project I see only an empty frame where the video preview for the file is and the main video window is also empty. The log shows various error messages. However, I cannot quite tell what causes the issues.

P.S.: Why does the forum block log/text files? How can I add the log if the maximal number of character is limited too?

There are a number of Linux threads in the DaVinci Resolve forum that might assist you.
