How do I set my screen resolution on Fedora 32 XFCE4?

I recently upgraded one of my machines from Fedora 28 (I think) to FC32 with XFCE4. After the update, my screen resolution is degraded to 640 x 480. Many items do not work at such a low resolution, because buttons falls outside the screen. When I tried to change the Display Settings, the only selection for the resolution is 640x480. There is no xorg.conf file that I can edit. There is no "system-config-display" that I can use to generate one. When I try to generate it by typing "Xorg -configure" I am told tht I must stop the X server first, but when I kill it, it respawns. How do I resolve this? This works on my other Fedora systems ... just not this one.
