boot process hangs/stalls on graphical screen with 3 blocks illuminated.
booting as normal, but hitting escape early, will revert screen to a console, which displays the old-school kernel and systemd startup lines, until it hits "Starting GNOME Display Manager" then it hangs.
If I edit boot command line by adding a 2 (runlevel 2) it will eventually (I came back later) leave that 3-block screen and go to console, the screen is full of accented Gs.
Ive edited boot command line, dropping the "rhgb quiet" and adding "2" it boots faster to same 'G' filled console screen.
console clears 'G's where it offers login prompt, typing clears lines after CR/NL once logged in, console is usable.
startx works at least partly it clears screen, paints a big mouse and waits. eventually it rendered the default background - meshy blue screen, and the mouse started working the background looks same as on my hires laptop, despite the large pointer and font.
Devices->Display shows blank resolution,
lspci -v says its an Intel 4 series chipset integrated graphics controller
this is on an old dell desktop with core 2 duo, uname -a has i686 (4.18-300 iirc)
I have some recollection of seeing discussion of switching display managers, Im gonna look at that next, hints welcome.

which means X, not wayland, I guess.
FWIW, this is a vga monitor. there are some odd resolution switches during boot and Dell logo gets 4 interleaved ghosts on screen during part of these switches. maybe corroborating failure to read any monitor resolution

I managed to switch to lightdm. boots to graphical screen, at LOW resolution (same big mouse/pointer) but usable, at least a little bit.
Im gonna try a different monitor soon. but I think im stuck with vga on box
