Zwischenzeitlich habe ich es mal mit meinem Zweitlappi und Suse Leap 15.3 probiert:

This is read-edid version 3.0.2. Prepare for some fun.
Attempting to use i2c interface
No EDID on bus 0
No EDID on bus 1
No EDID on bus 2
No EDID on bus 3
No EDID on bus 5
No EDID on bus 7
2 potential busses found: 4 6
Will scan through until the first EDID is found.
Pass a bus number as an option to this program to go only for that one.
