nvidia (proprietary) output not resuming after suspend

After suspend+resume, the display connected to my NVidia card (3050 ti) with proprietary drivers on Manjaro keeps getting 'no signal' about 95% of the times. All of the standard tricks (updating bios, toggling nvidia-drm.modeset, various other kernel flags, various XOrg options, using NVidia's custom systemd suspend service, ..). I'm using the NVidia card as part of the second seat of a multi-seat setup (using loginctl and lightdm). This may be related, as the second seat doesn't allow Virtual Terminal switching, which the NVidia custom systemd suspend service seems to be using to trick XOrg into reinitializing. (After many hours, I've found a workaround. I'm posting this to save others the headache, and perhaps to discover a less hacky solution.)
