Public bug reported:

After having problems with the nvidia driver 470, I reverted to the
nouveau driver, only to find that using suspend or shutdown in the XFCE4
menu just returned to the login page.  However, I found that using the
'shutdown' or 'pm-suspend' commands worked OK.

Checking syslog after a failed suspend lead me to /etc/systemd/system
directory:

lrwxrwxrwx  1 root root    9 Aug 25 15:04  nvidia-hibernate.service -> /dev/null
lrwxrwxrwx  1 root root    9 Aug 25 15:04  nvidia-resume.service -> /dev/null
lrwxrwxrwx  1 root root    9 Aug 25 15:04  nvidia-suspend.service -> /dev/null

Also, there were two directories containing links to the above 'masked'
services. Deleting those links restored suspend and shutdown
functionality.

drwxr-xr-x  2 root root 4096 Aug 26 18:14  systemd-hibernate.service.requires/
drwxr-xr-x  2 root root 4096 Aug 26 18:08  systemd-suspend.service.requires/

Obviously a problem in removing all the nvidia settings.
