When the nvidia driver packages are uninstalled, they leave some symlinks that prevent suspend.
I've deleted them while figuring out what the problem was, however, they should be these:
/etc/systemd/system/systemd-suspend-service.requires/nvidia-suspend.service /etc/systemd/system/systemd-suspend-service.requires/nvidia-resume.service /etc/systemd/system/systemd-hibernate-service.requires/nvidia-suspend.service /etc/systemd/system/systemd-hibernate-service.requires/nvidia-resume.service
There's not reason to leave them once the driver is uninstalled, and it's hard to figure out the problem, so they should go away when the packages are uninstalled.
