You may need an xorg.conf file to make the system load the radeon driver. Udev is failing and not working out what refresh rates the system can do (probably a cheap screen. You can override this with:

gksudo gedit /etc/X11/xorg.conf

There are LOTS of example files you can use but you will be wrestling with this file (Which is blank by default) until you get a good display. If you turn up blank I can have a go at formulating one.

hello
good answer
i entered
gksudo...
in the terminal but for
sudo lshw...
i read the same parameters
can i look for these files in interent?

yes it will, until you modify /etc/X11/xorg.conf

howto modify?
and i looked for /etc/X11/
no xorg.conf found
do you formulate me one?

There isn't one by default. If one exists it will be used. Did you find any examples online?

i found http://cgit.freedesktop.org/xorg/driver/xf86-video-radeonhd/snapshot/xf86-video-radeonhd-1.3.0.tar.gz
and try to install
no video works
maybe i do it wrong
no directory found for installation
i saved http://cgit.freedesktop.org/xorg/driver/xf86-video-radeonhd/snapshot/xf86-video-radeonhd-1.3.0.tar.gz in "home"
