Raw noob here. No experience with Linux. Decided to try Linux on an old Dell OptiPlex 580 to see if I could use it to run some CAD programs for a small desktop CNC mill I just picked up.
There is a Radeon HD 4200 video card on this, and I have a VG1930wm monitor whose native resolution is 1440x900 which resolution was available on Windows. Right now the highest resolution available is 1024x768. I spent a few hours trying to sort out what to do but figured I'd save myself additional pain and ask. What would be the easiest way for me to allow this resolution given I have about 3 hours total Linux lifetime experience (and I'm older than dirt so don't want to drop dead before I sort it out)?
Your help appreciated.

Out of the box - not much for it
Its a bit older.. But it can be used and at a higher res..

The link just above is one of mine where I have a 4200..
I was able to set a higher res by modifying the "xorg.conf" file
Path: /etc/X11/xorg.conf -- Open with Admin Rights (Rt Click) or launch from terminal
sudo leafpad /etc/X11/xorg.conf
or from within terminal
sudo nano/etc/X11/xorg.conf
The below is a copy of my xorg.conf --- Note the Selection "Monitor" and Section "Screen" sections.
*Notice I have REM marks "#" these are not used in my file, but may work for you.
You'll want to test as my resolutions/refresh rates/syncs may not match your monitor.
Also, setting a non supported resolution can/will render an unusable output. You would need to recover from a TTY session
Where CTRL+ALT+F1 will open a tty1 session and CTRL+ALT+F7 will return.
In TTY access file '#" the invalid line, save and 'reboot'.

Might be worth a shot...

Thanks very much. I will give it a try after work.
By the way I can work with the resolution the way for general use but since I'll be designing stuff and everything is a bit stretched I assume that 'stretching' will also distort the view in the CAD and other drawing programs.

Just wanted to thank you. That pointed me in the right direction. Using your sample I searched for modeline settings online that matched and then was able to add that line and remove the stuff that didn't belong. I had to use the monitor horizontal/vertical screen adjustments to tweak it the final few pixels as I didn't know what those modeline settings meant and didn't want to twiddle with them. Looks like I am good to go.

Good to hear @stormvisions :D :D
If you havent yet, making a backup would be a good idea.
In LL3.x its SystemBack and in 4.x its Time Shift..
Kind of similar to windows restore point, but better ;D

Will do - thanks again.
