Hello Marko,

Congratulations, I worked exactly like you said.
Thank again.

Well, obviously, you want to (re)move these files as well. The idea of removing 
xorg.conf is to start with a clean configuration. You want to remove any and 
all changes you have made to xorg.conf and xorg.conf.d/ directory. 
Delete/rename the xorg.conf file, and make sure that the directory xorg.conf.d/ 
is empty.

Once we fix the loading of the proper driver, we can re-add the configuration in 
order to fix your resolution problems. Also, I could bet that your resolution 
will work out-of-the-box, once the nvidia or nouveau driver is properly in 
place.

Currently, you have nouveau loading, and the 00-nvidia.conf file is making it 
fail (remember, never both drivers at the same time!). Your system then falls 
back to the default generic vesa driver, which doesn't support resolutions 
beyond 1024x768. That is why your resolution doesn't work properly.

So, remove the xorg.conf and empty the xorg.conf.d, and then do all the steps 
as I explained in the previous e-mail.

Ok, it would be best to do a

   yum remove akmod-nvidia kmod-nvidia xorg-x11-drv-nvidia nvidia-xconfig

We will re-add these as necessary later. Remember, remove *everything* nvidia-
related. All rpm packages and any configuration files. You want to start with a 
clean, default Fedora configuration for X.

The nouveau driver, if present on your system, will be loaded by the *kernel*, 
during boot procedure, long before xorg.conf is looked at. The xorg.conf file 
has nothing to do with loading nouveau.

If instead you want to use nvidia driver (and you do), then nouveau would be 
removed, the kernel would boot with the generic vesa driver, then it would 
read  the (nvidia-created) xorg.conf, and then load the nvidia driver when X 
gets started.

That is how it works. Nouveau and nvidia drivers work quite differently, get 
loaded at different times, one doesn't need an xorg.conf and the other does 
need it, etc.

So again, please --- if you want to fix your problem, you need to remove any 
and all traces of nvidia software from your system, remove any custom X 
configuration files, perform a "yum update", reboot into the latest kernel, do a 
"yum install akmod-nvidia", and reboot into the same kernel again.

That should be enough to make your graphics work properly. If it still doesn't 
work, send us the /var/log/xorg.0.log so that we can see what else is failing.

HTH, :-)
Marko
