problems with monitor resolution configuration

[ingesis]

So, here I'm with my new intent to have a linux distro as my main S.O. I'm experiencing problems with my monitor resolution configuration and I've found this forum and thread "linuxforums.org/forum/red-hat-fedora-linux/165449-screen-resolution-fedora-13-a.html", and rigth now I'm with the problem of can not run my linux distro because my Fedora doesn't recognize my xorg.conf spec.

So, my question is: how can I access the main partition to change the xorg.conf file from a Live CD distro of Fedora? I've tried with the solution offered by devils casper

Try this

su -
mkdir temp
mount /dev/sdxy temp
cd temp
touch test
rm test

Does it allow you to create and delete file test?

and it's not possible to me to edit the xorg.conf file because I just can read from this partition.

Besides of this, I can not configure the way the partitions are being mounted because Live CD does it for me. They just appear at the moment I open nautilus and they do not appear in the /mount directory neither.

I've tried to find the xorg.conf file with the find command and it finds it in this place:

./media/cb6c77d7-4f41-42b6-a9fd-5ec59b9dac3d/etc/X11/xorg.conf

so I've unmounted the partition and when I try to mount it again it just responds:

mount: /dev/sda2 already mounted or temp busy.

What should I do? I'm working with Fedora 14 at 64Bits.

I could give more info but I just don't want to make this post bigger.

You will find xorg.conf in /etc/X11. The mount point in /media is for external media that is auto-mounted. /dev/sda2 is probably your swap partition. It will remain busy as long as the system is running. Anyway, post the output from the 'df' and 'fdisk -l' commands here.

Thanks for the help Rubberman

This is what I get with 'df'
