After a bit of relection on the issues (catalyzed, in part, by the
realization that merely reverting the OS back to
stable/12-n233561-42cb78bdd49 did not produce a "working system"), I
noticed that the other laptop has a slightly different video controller:

g1-55(12.2-S)[1] pciconf -lv | grep -B 2 Quadro
vgapci0@pci0:1:0:0:     class=0x030000 card=0x05cc1028 chip=0x11fc10de rev=0xa1 hdr=0x00
    vendor     = 'NVIDIA Corporation'
    device     = 'GK106GLM [Quadro K2100M]'

g1-48(12.2-S)[8] pciconf -lv | grep -B 2 Quadro
vgapci0@pci0:1:0:0:     class=0x030000 card=0x17b01028 chip=0x13b610de rev=0xa2 hdr=0x00
    vendor     = 'NVIDIA Corporation'
    device     = 'GM107GLM [Quadro M1200 Mobile]'

So, on a hunch, I tried replacing x11/nvidia-driver (which had
recently been updated) with x11/nvidia-driver-390.

And that allowed X11 to work.

I plan to follow up in -ports@, Cc:ing folks involved in that update.
