Indeed, my kernel was too old.
I have upgraded from "linux-3.10.17" to "linux-3.15.8" and now it works:

Now, all my previous problems are solved:
- 1 screen only used (the external VGA screen): solved! (the two screens are working together)
- the font is too big: solved! (the font size is normal)
- the "xrandr" command tells me "Failed to get size of gamma for output default": solved! (this message is not displayed anymore)

But I see a last problem: I have no 3d acceleration!
As you can see here:
$ cat /var/log/Xorg.0.log | grep Direct
[  7567.271] (WW) RADEON(0): Direct rendering disabled

The full xorg log is available here: http://pastebin.com/hSKjXsvL

Do you know how to have 3d acceleration please?

Thank you.
Best regards.
