I doubt, this issue was caused from an Xorg update six months ago ... and as you know Xorg is part of "ports" not part of "FreeBSD".

and yes, my suggestion worked before, so I'm confident it will work for you too:

I must need better glasses (or a larger screen )... must be -n, not -m

If you can believe this, I wiped my hd again, and this time installed Freebsd 11.0 with my new toy, "boot only" cd, the repos fly.

Everything went fine, till I got into the Xs, bad resolution! I put the xrandr cheat codes in my .xinitrc as shown above.

But then, I saw this thread on the forum:

and it is similar to what you said ASX, I erased the xrandr lines in my .xinitrc, and rebooted, came back and it was fine and dandy like it should be.

Thank you, paesano! Gracias mil!

Comented the xrandr codes in my .xinitrc, and rebooted and bob's your uncle!

No more problems.

Thanks to ASX and everybody else...

PD: you were right on the money, ASX
