Hi everyone,

I'm still a total newbie with linux...I'm running FC7 on an HP machine that has a 1.3 Ghz Athlon processor and 756 MB of memory. My screen resolution was running fine at 1028x786. However, I just rebooted my machine and my screen resolution is now gigantic at 800x600. When I go into my display options, these are my only choices:

800x600
600x480
400x300
320x240

Also, I could have sworn I had a refresh rate of 72 or 75...now the only options are 60hz and 56hz. Here's some config info:

From hardware lister:

VGA compatible controller

vendor: nVidia Corporation
bus info: pci@0000:01:05.0

Any help would be greatly appreciated.

do
$ system-config-display
and select the monitor that you have attached to your system.
then you should be able to change the resolution.

Doing the above command does not work for me. My monitor does not get written to xorg.conf

I have a similar problem. My fresh rate is 60.02, but I have options of 50 or 51.
I have a Nvidia FX-5200 graphics card and Samsung SyncMaster 170N monitor.
I've tried livna's rpm, same problem. Now I have Nvidia's kernel module installed. Same problem.
I am open to suggestions.

You both need to edit your /etc/X11/xorg.conf file and add modes for whatever resolution you want. The line can look like this:
Modes "1280x1024" "1024x768" 800x600"
or
Modes "1280x1024" "1024x768"
or
Modes "1280x1024"

Up to you if you want to play with refresh rates but I bet just editing the modes line will be enough. Also, if the VertRefresh and HorizSync are wrong for the monitor that screws things up. Third, try using the 'vesa' driver until you get squared away, then move to the correct driver if you wish.

The FX5200 card works well with the NVidia driver. I'm using that card in a desktop here.

Just a thought on how to fix your issue.
