Having had a very similar problem (I actually wanted a resolution that
would still let me see the top nav bar in gnome), I took these notes
for myself. I think they are pretty adaptable but it was super
complicated to find.

So, first, you need to get the modeline with something like:
cvt 1600 850 60

then get your display name by running
xrandr

then in, /etc/gdm/Init/Default

xrandr --newmode  "<name of mode>" <modeline from above>
xrandr --addmode <display name> <name of mode>
xrandr --output <display name> --mode <name of mode>

an example of the above
xrandr --newmode "1600x800_60.00"  104.25  1600 1688 1848 2096  800
803 813 831 -hsync +vsync
xrandr --addmode qxl-0 1600x800_60.00
xrandr --output qxl-0 --mode 1600x80_60.00

spice/qxl resolution setting?

I'll have to give that file a try, maybe it will work
better than the xinitrc.d directory. Thanks for the
pointer.

My script to set the mode is a little less complex
because I just want it to use an existing mode it
already knows about.
