--- Comment #16 from Michael Zapf <forum...@mizapf.de> ---
Maybe this is another indication that something goes wrong:
(screen at 1920x1200)
michael@capella:~> xrandr --verbose | grep EDID -A16
EDID:

That is, there is no EDID data anymore.

I was looking for some tool to read the EDID channel, but I was not yet
successful. I am using openSUSE. I tried to download and compile read-edid, but
I get an error message from cmake about a missing setting of X86_LIBRARY.
Then I found a python tool on Github (edid-rw), but I cannot find the smbus
python module (not in the repositories).
