All Black Display Trouble one or two Display all Black

[sunniboi]

I always have a black screen. Because, as you can see, only the first screen is recognized. An external screen is supported on Wayland Debian Buster. Is this a general problem that is still not resolved? Picture is black. No matter what screen! How can I permanently rewrite the screen in the config? Where can I find the config? Because a setting in the program. Has made no change.

Fail

[X11Input :: InputThread] Error: could not get an image (with shared memory)!
This usually means that the recording area is not completely within the screen. Or have you changed the screen resolution?
[X11Input :: InputThread] Exception 'X11Exception' in the input process.
[FastResampler :: Resample] Resample rate is 1.0000 (was 0.0000)
