No file /etc/X11/xorg.conf created on system.
The problem does not occur any more. I removed nomodeset from the kernel
command line, and the X comes up correctly. The only time it did not was
after I did a fresh install, and the monitor was blinking trying to sync
the video card with the monitor. Now it does not happen.
I'm at a loss to explain.
Let's close it for now and hope that it was just some installation quirk. Please, reopen with new versions of files if it happens again.
