I am guessing that this is latest version?  Do you happen to know if
Linux Mint uses Gnome or KDE as the user interface?  Would you also
happen to know which version?

Should return something similar to the following:
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series
Chipset Integrated Graphics Controller (rev 07)

Is this a CRT (giant tube based thing) or an LCD monitor?  If it is a
CRT how old is it?

- From the command line (bring up xterm, konsole, gterm, or any other
terminal.  Type "xrandr" to see all the supported modes.

On my laptop, the output of xrandr looks like this:
$ xrandr
Screen 0: minimum 320 x 200, current 1440 x 900, maximum 2720 x 900
VGA disconnected (normal left inverted right x axis y axis)
LVDS connected 1440x900+0+0 (normal left inverted right x axis y axis)
304mm x 190mm
   1440x900       60.2*+   59.9     40.2
   1360x768       59.8
   1152x864       60.0
   1024x768       60.0
   800x600        60.3     56.2
   640x480        59.9
HDMI-1 disconnected (normal left inverted right x axis y axis)
HDMI-2 disconnected (normal left inverted right x axis y axis)
TV disconnected (normal left inverted right x axis y axis

Synaptic is the wrong place to look.  Most modern Linux distributions
will automatically install the correct drivers.  The vanta is quite old
so this may be the problem.

Most recent versions of the distros I see do not really modify this file
anymore.  Both KDE and Gnome have very capable GUI driven control panel
widgets for controlling the resolution.  FYI the GUI widgets are now
just front ends to the xrandr command line utility.

Of course all of the above is moot if Linux Mint is using older versions
of Xorg.  I have no idea how current this distro is.  I have never
actually seen Mint in action.
