Comment:
Probably not the same as #195 (I may comment there as well).  Void's `greetd` installation is slightly broken, in that no default shell is assigned to the `_greeter` user, or `$SHELL="/sbin/nologin"`.  Arch at least assigns "/bin/bash" as shell for the greeter user.  Greetd references the "$SHELL" variable in `/etc/greetd/config.toml`. Users often replace $SHELL with something else, accidentally eliminating the bug. 

The easiest solution is to:

`sudo chsh -s /bin/bash _greeter`

or you may edit `/etc/greetd/config.toml`  as root, changing `$SHELL` to `/bin/bash` or whatever you prefer.  Alternatively, you may also create a default `SHELL="/bin/bash"` in `/etc/environment`.
