fresh install Kubuntu 14.04 (15.10 same problem) XServer never starts

[Gregor Leskovšek]

When I login (right password) the xserver starts loading but then after
10-15 seconds I get back login screen
I have Radeon EAH4350 SILENT/DI/512MD2(LP) (or smth like it used from
another (brothers) computer) and Intel S5000 SPL Xeon motherboard.

I am unable to start XWINDOWS. In text mode I reinstalled plasma and
kubuntu desktop (I do not know if there is a trick, because that should be
a bunch of packets but it processed only few lets say 3-5, I did it so:
sudo apt-get purge plasma-desktop kubuntu-desktop; sudo apt-get install
plasma-desktop kubuntu-desktop)

I have attached the log file.
I think the problem is here(see the excerpt from log below ...) (but I am a
newbie), before I managed to install Kubuntu 14.04 x64 to server, but I got
only one VGA port without the Radeon and I had to use 800x600 resulotion,
so I could not use it, maybe also other things are in game - I also updated
BIOS.
