Same here, with Nvidia 455.45.01 on Ubuntu 20.04. In fact I've been
facing this for years, since 18.04.
The workaround I'm using is to call nvidia-settings via a shell script
in Gnome's Startup Applications.
It's a bit annoying because it only applies after you log in, but has
the additional benefit that you can execute manually if your monitors
get out of sync for some reason (handy if you use a KVM that forces X to
re-detect monitors).
You can save your config via nvidia-settings to a separate location, and
then extract the exact parameters for each monitor. Here's mine:
# monitor-reset.sh:
sh -c 'nvidia-settings --assign XineramaInfoOrder="USB-C-0" --assign
CurrentMetaMode="DP-5: 1920x1200 +0+560, USB-C-0: 2560x1600 +1920+160,
HDMI-0: 1920x1200 +4480+0 {rotation=left}"' > /dev/null 2>&1

I tried running it with root (`sudo nvidia-settings`) and without.
I also generated an xorg file with `nvidia-xconfig`, and do the same
thing, but it still won't work.
