I've had this problem for a while. I reluctently just used windows. I no longer wish to be without linux on my laptop. Why is this happening:

Either with CD or USB install the installer cannot get past bootup (it stops at the kubuntu splash). With nomodeset it sometimes manges to get to the run or install option, but freezes shortly after. I eventually managed to get it installed by adding noapic acpi=off and nomodeset together as a last ditch effort.

However with these options on its just, terrible. It doesn't show battery options, the keyboard, even on a light and fast keypress, occasionally spams keys as if I had been holding them down for several seconds. As well as not being able to install AMD drivers without adding --force. Which I just tried and now it starts without a GUI. Attempting to load the GUI with the startx command also fails.

My laptop is a Clevo P570WM with Intel i7-3970X CPU and 2x AMD Radeon HD 7970M GPU's. The Ubuntu distro is Kubuntu 14.04 x64.

Edit: Forgot to say I also tried to fix the problem by updating the kernel to 3.14.1-generic, didn't help.

The solution was to reinstall kubuntu 14.04 with the standard desktop live CD with extra boot options other than acpi=off, as that option was the 1 that caused the issues I described.

To get the installer working It needed to be booted with nolapic to prevent freezing and nomodeset for the GUI to show. These options carry over to the installation.

After that installing the AMD fglrx drivers from apt-get allows you to disable nomodeset and boot with only nolapic. That is achieved by editing /etc/default/grub as root, removing nomodeset and then running update-grub as root.

Other problems that occurred were:

The installer freezing at 93% when copying logs. To remedy that simply reboot. Its late enough in the install process to be inconsequential. Change to another tty, eg tty1 by pressing Ctrl+Alt+F1 if the "Try Kubuntu" option wasn't used. Then run the reboot command.

Grub failing to find the UUID of the boot partition. To remedy, reorder the HDD's in your bios such that the boot drive where kubuntu is installed is 1st.
