Issues getting external DVI monitor setup
I have LinuxMint Cinnamon installed on my laptop and recently acquired a docking station for it.
Since the docking station has a DVI port, I decided to connect my ASUS wide-screen monitor to it. Unfortunately, it has not given me a display yet. My ultimate goal is to have this screen and my laptop working as independent displays.
Below are the results of running inxi -Fx:
System: Host: Kanga Kernel: 3.8.0-19-generic i686 (32 bit, gcc: 4.7.3) Desktop: Gnome Distro: Linux Mint 15 Olivia Machine: System: TOSHIBA product: TECRA A8 version: PTA83U-02V02C Mobo: TOSHIBA model: Portable PC version: Version A0 Bios: TOSHIBA version: Version 1.50 date: 08/30/2006 CPU: Dual core Intel CPU T2300 (-MCP-) cache: 2048 KB flags: (nx sse sse2 sse3) bmips: 6649.96 Clock Speeds: 1: 1000.00 MHz 2: 1000.00 MHz Graphics: Card: Intel Mobile 945GM/GMS 943/940GML Express Integrated Graphics Controller bus-ID: 00:02.0 X.Org: 1.13.3 drivers: intel (unloaded: fbdev,vesa) Resolution: 1280x800 at 60.0hz GLX Renderer: Mesa DRI Intel 945GM x86/MMX/SSE2 GLX Version: 1.4 Mesa 9.1.7 Direct Rendering: Yes Audio: Card: Intel NM10/ICH7 Family High Definition Audio Controller driver: snd_hda_intel bus-ID: 00:1b.0 Sound: Advanced Linux Sound Architecture ver: k3.8.0-19-generic Network: Card-1: Intel 82573L Gigabit Ethernet Controller driver: e1000e ver: 2.1.4-k port: bfe0 bus-ID: 01:00.0 IF: eth0 state: down mac: 00:15:b7:42:be:5c Card-2: Intel PRO/Wireless 3945ABG [Golan] Network Connection driver: iwl3945 ver: in-tree:s bus-ID: 02:00.0 IF: wlan0 state: up mac: 00:18:de:27:fb:dc Drives: HDD Total Size: 80.0GB (20.7% used) 1: id: /dev/sda model: FUJITSU_MHV2080B size: 80.0GB temp: 38C Partition: ID: / size: 73G used: 16G (23%) fs: ext4 ID: swap-1 size: 1.06GB used: 0.14GB (13%) fs: swap RAID: No RAID devices detected - /proc/mdstat and md_mod kernel raid module present Sensors: System Temperatures: cpu: 51.0C mobo: N/A Fan Speeds (in rpm): cpu: N/A Info: Processes: 174 Uptime: 48 min Memory: 507.9/994.4MB Runlevel: 2 Gcc sys: 4.7.3 Client: Shell inxi: 1.8.4

I am still very new to this, so I don't know exactly what I am missing to get this setup. And, to be honest, everything I have been reading is confusing me even more.
Any and all help is GREATLY appreciated!
UPDATE: OK, I noticed this in the XRANDR documentation:
Gnome places the menu bar on screen 0 and thus with the Intel chip and driver Screen 0 (the external VGA monitor) will always be the default display if it is connected. This applies even if the external monitor is switched off but the cable connected: if you have a blank laptop monitor check if you have anything plugged in to the VGA port. Also beware that desktop icons and windows can disappear into the invisible parts of the virtual display.
Just so you know, I have gone through the steps of adding modes and attempting to add the DVI as an output, but I consistently get this error:
xrandr: cannot find output <insert mode designation here>

Does you laptop have a external monitor port, if so when you connect you monitor to it does that work. Most laptops have a function key that controls external monitor support. That key usually is multi-function like external off, external on, internal off, and sometimes more they usually rotate thru the options. Since docking stations are usually just a pass-thru I would get the monitor working first connected directly to the laptop, then try it with the docking station.
I don't use Mint but its probably the same, my Linux the Display setting tool also turns the 2nd monitor on and off so you want to check that too. My Linux it not only turn the external montior on and off it control if the display is mirrors or extends the main display.
So check you Display settings in Linux and see if 2nd monitor support is on and if that doesn't help check you laptops display settings.

I think therein is where the problem lies; there is an external monitor port, but it is VGA instead of DVI; the DVI port only exists on the docking station. I am guessing that is why the DVI port isn't registering.
Is there a possible/feasible way to get Linux to see that port, or am I stuck with working with a VGA setup for my external monitor?

What do you mean stuck with VGA is just a different type of connector, your video chip is what determine what level of video you're going to get. My laptop only has a VGA video port, but I run it into my TV and it gets full HD resolution of the TV. Many laptops have VGA and HDMI ports because they are physical small.

OK, according to the manual, the DVI port on the docking station supports DVI-D type.
