You found it, but yes, I was not there.
Hi again.
I found out, what I think is the main reason for the issue(s).
The monitor is not detected.
I have done clean installs with and without DVI connected, and also with VGA connected. The monitor in focus is an Acer X233H.
I also tested it with an Acer AL1715 -also for VGA and DVI-.
None of the monitors were detected.
The not detected is as far as I can see, the reason for my troubles.
Then I presume, that it's necessary to use xorg.conf, even it's ugly, that none of the monitors got detected.
What say folks ?.

Long answer: The method of monitor connection should not matter. The dependencies are that the monitor supports the DDC protocol for reading the EDID, the EDID needs to be in a valid readable structure (this standard has changed several times), and the graphics device driver must be able to read that structure. There have been problems in particular with getting these dependencies to work together with wide screen and LCD displays. Often the issue is not that the monitor's EDID is not being detected, but that the driver cannot resolve the native resolution or proper timings. To see what your driver is retrieving from the monitor, try this: Boot into runlevel 3, login, and at the prompt do (note the precise syntax): startx -- - verbose 6 The server may start a session, but more likely with the new X you will just get a solid color screen of some sort. Kill the server (Ctrl-Alt-Backspace twice). Switch to root and read the X log. You should see an EDID section showing what the driver is reading and interpreting from the monitor. Short answer: Yes. If the monitor and/or graphics driver cannot resolve the resolutions, you will need to instruct X what to use. Usually a modeline (cvt will provide that) will take care of that. While you can construct an entire xorg.conf, you may get by with just adding the modeline to /etc/X11/xorg.conf.d/50-monitor.conf.
