How does the user set the resolution the display will show when logging into the desktop?
I guess that you want to adjust the resolution due to HiDPI?
On my system, the login screen is taken care of by lightdm, so I adjusted the DPI settings (`xft-dpi`) in `/etc/lightdm/lightdm-gtk-greeter.conf`
[greeter]
background=/usr/share/wallpapers/openSUSEdefault/contents/images/1600x1200.png
theme-name=Greybird-geeko
# xft-dpi = Resolution for Xft in dots per inch (e.g. 96)
xft-dpi=120
indicators = ~host;~spacer;~clock;~spacer;~language;~layout;~session;~a11y;~power;

There is a way to set the resolution of lightdm greeter in lightdm.conf. I can post an example but not until later as I'm travelling today.

Thanks. Any help is appreciated. Enjoy your travels.

I will try this from memory. Open /etc/lightdm/lightdm.conf in you favorite editor as root. Scroll down until you find a line
#display-setup-script =
Remove the # and add xrandr -s 1024x768(whatever your resolution is) and save and close and reboot.
display-setup-script = xrandr -s 1024x768
You can also create a script if the options get complicated. Then just insert the path of the script instead of the xrandr command. Lightdm must have access to the path of the script. So not in your home directory.

Thanks. However, entering:
display-setup-script=xrandr -s 640x480
did nothing. There was no change whatsoever.

Ok, I'll have to get back to you later when I can confirm the details.
Make sure the monitor is actually capable of the resolution.
640x480 is a real low resolution.

Thanks for your help. I'm not in a rush. I've put up with it this long, so I can certainly practice a little patience to improve my character. Heaven knows I need it.
My monitor is a 49" that can handle just about everything one can imagine, and certainly all the current standards including that one. It sure looks good during boot at 640x480. The GRUB menu is easy to see at a distance. Once at the desktop, things look great at 1280x800. My xrandr shows the ability to display 18 choices. It is always just a choice to get the resolution to display correctly without causing unused screen real estate, warped fonts and images or text too tiny to read.
Anyway, thanks again.

I just checked my laptop and I didn't need to make adjustment for it to work at 1600x900.
However, for the VM with a stripped down xfce4 I have to make this change. As mentioned, edit /etc/lightdm/lightdm.conf as root and added:
display-setup-script=xrandr -s 1600x900
This allowed the greeter to display at full resolution. It was originally a much lower resolution but not sure what it was.
I would try different resolutions to see if one would work. It may also have to do with how the monitor is connected and type. You may need to also include this info. xrandr will give you the info. See
man xrandr
for details and options.

Thank you for this:
display-setup-script=xrandr -s 1600x900
I was able to change my login screen resolution to 1368x768. It worked after a reboot.

There remains an obvious flaw somewhere in the setup procedure which appears to hide the method of making things easy to set, and which appears to override whatever we users are able to figure out in our settings.
Currently, my boot-up display is very good up until the LUKS password comes into play. At that point, the settings are overridden and the text reverts to something very tiny on the screen. After that, the rest of the boot display gets too small again.
Once the login for the Xfce desktop is reached, it too is too small.
The whole process is a mess in that it lacks user control in a simple and centrally-located manner.

I don't know if LUKS has anything to do with it but you can set the resolution at boot in /etc/default/grub as root using your favourite editor.
nano /etc/default/grub
look for #GRUB_GFXMODE=640x480. Remove the # and edit the resolution. You can also keep that resolution after grub with GRUB_GFXPAYLOAD_LINUX=keep in the same file. Once edited and saved you must run as root/sudo
update-grub
Reboot. The resolution must be supported by the frame buffer I believe. You can list several resolution and it will use whatever it supports.

These are the pertinent settings as they have been currently:
GRUB_GFXMODE=640x480
GRUB_GFXPAYLOAD_LINUX=640x480x24
GRUB_GFXPAYLOAD="keep"
GRUB_TERMINAL="gfxterm"
