My cable has one end male and one female, and I don't have a spare or a
useful adapter. I tried swapping in another monitor using the cable from the
problem build. The resolution problem persisted. So the cable is still
a suspect.

Thanks. I tried that and was again unsuccessful.
I guess this is in software or in the cable. I could buy another cable, but
I'm the process of getting a new desktop built anyway. I think I'll just
live with this until I can abandon ship.
Thanks for all your efforts, Felix. I did learn a few things.

If nothing yet suggested works, a more flexible solution than a manually
generated
& hard-coded modeline applied after X has already started is letting the server
generate one on startup based upon the formerly provided EDID basics I retrieved
from your old Xorg.0.log:
Ranges: V min: 50 V max: 61 Hz, H min: 30 H max: 83 kHz
Save the following as /etc/X11/xorg.conf.d/40-vga.conf:
Section "Monitor"
Identifier "DefaultMonitor"
VendorName "Dell"
ModelName "U2412M"
HorizSync 30-83
VertRefresh 50-61
Option "PreferredMode" "1920x1200"
EndSection
This early application ought to make it behave more like it used to, unless the
problem is actually inside the display. I've had two 1920x1200s die on me, a
Dell
made in 2005 and a Lenovo made in 2009. My 2560x1080 Dell only lasted 5 years
before refusing to power on any more. :~( The two 1920x1200 I have now are 2011
NEC and 2012 Samsung.
