Nothing should be displayed.  The command will switch the mode.  "auto" means to switch to the default.

You could also try....

xrandr --output VGA-1 --mode 1152x864  to see if that makes a change....

I noticed you "ssh'd" into the system.  I don't know that xrandr would be effective when using a "remote" session.  Can you try entering on the actual console?
