This may or may not work, depending on how things are set up.  In the
KDE Control Center, it's under Peripherals->Display->Size and
Orientation.  You will only be able to choose Modes you have defined in
your xorg.conf , so if you only have 1 Mode listed, that's all you'll be
able to use.

Er, no.  Every modern distro is using Xorg, so the file is
/etc/X11/xorg.conf .  Even then, editing that config file doesn't
necessarily change the Mode.  Look at this section from my xorg.conf :

Section "Screen"
  DefaultDepth 16
  SubSection "Display"
    Depth      16
    Modes      "1280x1024" "640x480" "800x600"

...right, 3 Modes defined.  The display comes up in 1280x1024 by
default, and can be switched to 640x480 or 800x600.  If I added
"400x300" to the end of the Modes line, the display would still start
off in 1280x1024.  Nothing would change until/unless I did "xrandr -s
400x300" or "xvidtune -next" several times or Ctrl-Alt-KP+ several
