Hi Fred and others,
Hope you're around today. I can't believe that it took this long for me to get around to working on my desktop (been mainly working off my laptop with dual boot). Anyway, tried to make the suggested change to the xorg file and found a couple of issues.
When I went into the nvidia settings to change the resolution after rebooting, there is an option to "save to x configuration file". When I select that it allows you to preview the file and the screen section looks like this:
Option "metamodes" "1440x900 +0+0; 1024x768 +0+0; 832x624 +0+0; 800x600 +0+0; 640x480 +0+0; 1280x1024 +0+0"
Modes "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
The path to the file is correct: /etc/X11/xorg.conf
After that I opened the file with the text editor and this was what I found in the screen section:
Identifier "Default Screen"
Device "nVidia Corporation NV11DDR [GeForce2 MX200]"
Option "AddARGBVisuals" "True"
Option "NoLogo" "True"
Option "AddARGBGLXVisuals" "True"
Modes "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
As you can see they are quite different and the desired resolution of 1440x900 is not in the saved version. Any thoughts on what may be happening.
Also, I tried simply adding 1440x900 to the modes line and commenting the rest. When I did so I received this error:
You do not have the permissions necessary to save the file.
Please check that you typed the location correctly and try again.
But there is not option for adding a sudo to the save in the text editor that I could find. So how do I open it with sudo or with get permissions needed?
Thanks again for your help!
