AFAIK, not without restarting the desktop or display manager.

I've used pkill -u "user" to drop back to the display-manager but really 
want to get to the session as operable or to have it never go into stasis.

Could be a GPU driver issue. If you say what GPU you have (and what
driver) someone might be able to suggest a fix. Try posting the output
of 'inxi -G'.

If you are using nvidia drivers, before booting from whatever entry you use in the grub menus, edit that entry and check if the "nouveau" driver is black listed in the kernel options and if so remove those blacklisting options, and then boot with those changes to see if that causes the desktop to load. This issue appears to be the same issues I get when the nvidia drivers are not signed, this is assuming secure boot is active.
Also just to eliminate this as being a potential issue, when you edit the grub entry, check if after the kernel statement there is a statement to load the initramfs, as grubby (assuming this is still what is being used to build the grub menus on kernel updates) still has the tendency to not add the initramfs statement into the grub menus for the new kernel.
