However, when I hit "save to x-configuration" file, I get an error message saying, "Unable to create new X config backup file '/etc/X11/xorg.conf.backup'." I am running Mint 6 64Bit and a GeForce 8600 GT-XXX.
Also, Nvidia has 64 Bit drivers available for my card, and the drivers available online at Nvidia are much newer than the driver installed on my computer (I cannot tell if the driver Mint 6 driver manager installed is 64-bit or not). I want to install the new driver, but after I download it I cannot figure out for the life of me how to install it. Any suggestions? I've tried typing the command in the terminal as included in the instruction at Nvidia to no avail.
Why do I suspect I am going to be visiting the dreaded terminal fix/install everything above? If the terminal is involved please help me out with very specific instructions as I have never understood the terminal and its command line functions.
Eureka! I hope this message finds you well (and that you will even see it) because I had the same exact problem you were having and I found what I believe is a permanent fix! No guarantees of course, I am a newcomer to Linux and have been struggling with the problem for a week now myself. I am running Mint 6 32bit, but I wouldn't see why the solution wouldn't work for you too.
Got the fix from this link http://www.linuxquestions.org/questions/linux-hardware-18/cant-save-my-the-screen-resolution-settings-on-ubuntu-8.10-681870/
. I would go and read his suggestions if I were you. However I didn't follow it precisely. Here is what I did:
1. Open the NVIDIA X Server Settings GUI
2. Click "X Server Display Configuration"
3. Set the Res and Refresh to the settings you desire and click APPLY.
4. Click the "Save to X Configuration File" button BUT DO NOT CLICK SAVE. Instead click the "Show Preview" button. Look over the settings there. They should match your desired settings for Res and Refresh rate.
5. Highlight the entire text and COPY using Ctrl+"c"
6. Exit the NVIDIA X Server GUI
6. Open a terminal and type: sudo gedit /etc/X11/xorg.conf
7, Highlight the entire text and REPLACE it by PASTING using Ctrl+"v"
8. Save the file and exit.
9. You should still have a terminal open (I did anyway). At the terminal prompt type: sudo reboot
In Grub, select the normal boot process (not recovery) and ... well, that should be it. It should boot up with your desired settings. It did for me. I hope you see this and it works for you too. Good luck and take care.
