Edita el fichero /etc/X11/xorg.conf
Al final del fichero podrás ver unas linear parecidas a esto:

EndSubSection
SubSection "Display"

EndSubSection
SubSection "Display"

EndSubSection
Option "AddARGBGLXVisuals" "True"
EndSection

simplemente escribe tu nueva resolución la primera de todas las lineas, "1280x1024" en tu caso. Y reinicia las X.
