removing then installing ( and reinstalling ) somethings might help ? unknown if it will
BUT a lot of times this will "fix" a system - things can get messed up .
you might try this
you will need to make a few lists and see what IS installed
most you can just use a pen and paper to take notes
1) remove all and any nvidia
for a list of what is installed
Code:
su -
rpm -qa | grep nvidia
then for any copy/paste the name into yum
Code:
su -
yum remove ??????
-- NOTE : DO NOT , DO NOT use the "y" option in yum
then remove any copy’s of "xorg.conf"
and remove ANY hidden nvidia file from your HOME folder ( .nvidia-settings-rc )
then reinstall "nouveau" ( Plymouth graphical boot dose need it )
i am thinking that maybe yum removed other things when you uninstalled this ? maybe?
Code:
yum search nouveau
-- then copy/paste it's name from the list
yum install ???????
doing a reinstall of xorg might help
same as above search then use "reinstall"
something like this
Code:
su -
yum reinstall xorg
this might bring a bunch of things so it might take a bit of time.
remove ANY blacklist that you put in menu.lis ( grub.conf)!!!!!!!
reboot
then see if the "nouveau" ( default) driver will let you change the screen resolution
I've followed all the instructions to uninstall any Nvidia driver and reinstall of noveau; and just get the same, after various restarts and trying to configure my monitor resolution with System -> Preferences -> Monitor, I get an Unknown model with 3 options 1024x768, 800x600 and 640x480.
So, in order to not get a headache with that refresh rate (60 Hz) I decided to reinstall the Nvidia driver from the guide with the akmod version. After this just got the same that yesterday, a lot of resolution options but not the ones I want.
Me again. I've made a fresh new installation of all my Fedora system and the first thing to config was my NVidia driver. It worked fine and just got the same resolutions previously described... although, I've noticed something, it seems that the plymouth app doesn't work at my HW since it starts in text mode and reading about this app in wikipedia I've noticed that it needs kernel-based mode-setting (KMS) to work. May be this KMS function should be configured previously in my system in order to have all the potencial of my Nvidia card.
What do you think?
I've been thinking about to put a new post in the forum especifically to my new problem, because the one that describes this thread doesn't have to be with Monitor resolution config.
I'd guess that for whatever reason, EDID isnt working with your monitor. Adding the required resolutions in xorg.conf should give you the modes you are after.
I'd copy over my xorg.conf file, but I'm testing nouveau (and its still yuck) so I dont have one.

Unless nVidia has changed direction, KMS will not work with the closed drivers. Well, it might be hackable somehow, but (AFAIK) offically the nVidia closed drivers dont support KMS, so trying to get KMS with the closed drivers could (would?) be asking for more headaches.
Interesting that fedora actually kicks you back to text mode, ubuntu with plymouth doesnt do that, it just looks UGLY.
*edit- that 'ugly with the closed drivers' problem is fixable with some hacking, but I dont like plymouth and I dont use it, so I've never tried myself.

Just FYI, the 60Hz = headache' problem is something you only get with CRTs. It shouldnt happen with LCDs, LED LCDs, etc..
Well, thanks for the comments... and I begin to think it would be better to get another monitor, this time an LCD, of course; it's just that I thought it would be a good idea to use my HW with a Linux distro since they have the fame to deal great with legacy stuff.
It would be possible that with another distro, maybe debian or ubuntu, this situation could be solved? Although I doub it since Fedora is very popular and for the know-how of Red Hat in the business.
If your thinking of getting an LCD, I'd get a LED LCD.The lower power consumption from LED LCDs is nice.
Its possible that changing distro will help. I cant be sure, its been a long time since I've had EDID problem, and when I get get the isue it was with other peoples hardware.
What would be the reason that the same HW, with the correct set of drivers, works better in Windows XP than in Fedora even when the linux distro is much more recent that the windows OS? It's possible that windows has a "feature" to make this happen?
The resolution in which a monitor works it's defined by the monitor specs or by the video card? I mean, if I want to get a new monitor should I consider to get a new video card to get the resolutions I wish?
I have no idea why EDID sometimes fails, but I doubt it has anything to do with windows. BTW, just to check if it is EDID try running this command-
grep -i edid /var/log/Xorg.0.log
Post the results (I'll bet you get "Unable to read EDID for display device")
The resolution is defined by the monitor, even some of the video cards I have that are _really_ old go to much higher resolutions than are common even now (like a GF4MX will go to 2048x1536). So anything that uses the 270.41.06 dirvers should work fine with the most common resolutions aroud now, 1440x900, 1920x1080, even the rarer but IMO much better 1920x1200.
Thanks for your help cascade9 but I think my problem is even bigger than EDID since it doesn't appear in the /var/log/Xorg.0.log. Right now I'm not in my Fedora machine but luckily I have a version of this file at hand and doing a search for EDID term indicates it doesn't exist any reference.
So, here it is the complete file, I know it's to long but I just don't know which part is important and which not (see attached file).
Is there something else that you can see is erroneous?
I've kept working on this problem and now I can have the resolutions I've being looking for, although I don't have the refresh rate I need. But I'm very pleasant with the results obtained.

Sorry, I totally missed this post. :S
That is what happens when you EDID isnt working, it wont appear in /var/log/Xorg.0.log.

Try lauching nvidia-setings as root. Then change the resolution to 1280x768 (or 1280x800 if you perfer). Then hit the 'Save to X Configuration File" button. That should save your current settings and keep them when you reboot.
Thanks for your help cascade9. Following your recommendation I finally managed to get "startx" use the resolution I need, but it was not so easy.
I tested a few other options that didn't work. Then I went with the option of let nvidia-settings do the work and didn't work either. So, I kept moving, copying and renaming the xorg.conf file and in some place I forgot to put a version of xorg.conf, then when I was making another try with the nvidia-settings tool I realized that a fresh new version of xorg.conf file was made and I ended with this one:
