Ok, as far as I know, this card should be supported by the open-source radeon 
driver. The other choice would be the ATI closed-source fglrx (or Catalyst, or 
whatever it is called now) driver, but I am not sure that it works with 
current Fedora.

I'll try to help you set up the radeon driver, but we need to do it step by 
step. (and you'll have a chance to learn a bit about Linux as we go... :-) 
...)

This shows that X (the graphics server in Linux) apparently doesn't know about 
the details of your graphics card, and uses some default settings. My guess is 
that it uses the vesa driver (this is a typical fallback if X doesn't have a 
better driver). Once we fix the driver, the output of xrandr should be different 
and more elaborate.

Sorry, I should have been more specific. The /var/log/Xorg.0.log is the file 
named Xorg.0.log, and it resides in the /var/log directory on the disk. Typing 
its name as you did in the terminal will attempt to execute it, and will fail 
because the file is not executable. Rather, this is a log of the X server 
events --- a text file, which can be read using a text editor.

So, if you wish to see the contents of the file (just for fun), you can open 
some text editor (find one in the menus), then open that file from within the 
editor --- choose to open a file, navigate to /var/log directory and select 
Xorg.0.log file to open and read. If you wish to use a terminal, you would type 

less /var/log/Xorg.0.log

to display its contents (use arrow keys or PageUp/PageDown to move through the 
file, type q to exit the less program).

More importantly, you should attach the file to the e-mail and send it to the 
list, so we can examine it. I see that you are using gmail account for e-mail 
--- open a reply to the list, and use the "attach" option in gmail to attach 
it (a file-chooser should open for you to pick a file, navigate to /var/log 
directory and select it, or type /var/log/Xorg.0.log in the "location" field).

N.B. The file chooser displays the contents of your home directory, by default. 
In the Linux file hierarchy, there is the root directory named /  which is 
analogous to C: in windows, and holds various other directories, like /var and 
/home. Your home directory is  /home/yourusername/  and its contents is 
displayed in the file chooser. You need to go "up" in the directory tree from 
that point (twice) to get to the /  directory, and then "down" to var and then 
log (which is inside var). In there you will find the Xorg.0.log file. I hope 
you won't have trouble finding it.

Once I examine the log file, I should be able (hopefully) to tell you what to 
do to fix the video driver. :-)

HTH, :-)

P.S. Please don't top-post on this list. Here it is custom to bottom-post, ie. 
put your reply *below* the text you quote in the e-mail, possibly deleting 
non-relevant parts of the quote along the way. Personally I don't mind if you 
top-post, but some other people might object. This is explained (among other 
things) in the list guidelines, 

  http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

which you might wish to read eventually. :-)
