For hardware details please see attached dmesg and X.org.log. Main feature suspected to cause issue is nouveau driver in conjunction with NVIDIA Quadro NVS450 graphics card.
The issue occurs with the Kubuntu 14.04 LTS (release) installer and the Kubuntu 14.10 (beta 2) installer on my PC.
Plug in USB stick or use DVD with installer ISO image. Reset. Kernel boots. The Keyboard=Man in Circle icon appears at the bottom. After some time the kubuntu logo appears and glows. Under 14.04 it then simply hangs forever, under 14.10 the screen messes up (black and white bricks) and then it hangs forever.
Switching to a text console in the interim shows that some part of the bootstrapping process succeeds, approximately up to the activation of the sound driver. The degree of completion of the initialization varies over different trials to boot into Kubuntu.
On some occurences, messages appear about problems with the nouveau driver.
I therefore activated the on-board graphics chip and made it the primary graphics device. This altered setup boots nicely into the configuration screen. I did not go further and did not install the system.
By the way, I have kubuntu 14.04 LTS running on that PC. It was flawlessly installed when I had a different mainboard. Due to a hardware defect, I had to change the mainboard. With identical setup now apart from the mainboard, the re-installation process fails.
