Si, claro.
O seguinte é um script que funciona para LVDS1 (normalmente laptops). Eu não sei se funciona em outros modos. Eu não testei isso.
Execute xrandr --prop | grep connected
para ver qual modo você usa. Se o LVDS1 estiver conectado , você poderá usar o script. e não "sobrecarrega" o hardware.
Tenha um diretório de usuários para scripts, por exemplo, mkdir ~/bin
Abra um arquivo vazio, gedit ~/bin/nxrez
Cole o seguinte script:
#!/bin/bash

# newrez v 1.0
# use xrandr to scale the display to a new resolution
# rewriten to handle mouse boundaries when scaled
# this requires setting a new resolution to the unused VGA1 device
# then scaling that for B display on the LVDS1 device
# modified by Moe to include zenity.
umask 000
# resolution can optionally be specified on command line
