Okay, so after a long (and I mean long) struggle, I have finally gotten my NVIDIA GeForce4 MX 440-SE to work with my Xubuntu install, I now am having a huge DPI issue. Which you can clearly see here:

I found a guide for fixing fonts at this link:

the following went fine, untill the third step where it directed me to follow directions at the following link:

The directions at the second link aren't as simple as its predecessor.

I'm supposed to enter:

xdpyinfo | grep resolution


xrdb -query

to find out my current DPI value.

When I enter:

xdpyinfo | grep resolution

I get:

resolution: 50x50 dots per inch

When I enter:

xrdb -query

I get:

*customization: -color

Now, according to the directions I'm supposd to edit directly /etc/X11/xorg.conf and under "Monitor" section add a line:

DisplaySize XXX XXX (in my case it's 270 203) (that's what the guide says, not me whoscheesemine)

Then it says:

XXX is calculated by using formula 25.4 * pixels (height or width) / DPI.

So, I guess I take 25.4 and multiply it by 50, okay well that gives me: 1270

Then I guess I'm supposed to devide that by my DPI... isn't that what I'm trying to figure out? I DON'T KNOW MY DPI OR I'D ALREADY HAVE IT SET!!!!! What am I supposed to do here?

Here is a link to my /etc/X11/xorg.conf in .txt format:

I would have just posted it on here, but I guess my post was too large.


Welp, after playing around with different monitor drivers it worked, so I suppose as the saying goes:

If it ain't broke, don't fix it.

Although, I still wish I could have fixed it manually..

I wound up just going to Applications -> Settings -> Screens and Graphics Then I set

Model: Monitor 1024 X 768

Resolution: 1024 X 768

at: 53hz

I still would like to set write my own monitor "driver" if anyone has tips on how to do so feel free to post it here, or pm me. Here are my monitor's stats:
