Interestingly, I can get Ubuntu Live CD 12.10 x86_64 to boot my Samsung NP700Z5C in Secure Boot (!) with "Try Ubuntu without installing" with all the factory BIOS settings, except that the FastBIOS mode has been disabled and the boot order has been changed accordingly to allow booting from the Live CD.
Now while I had my NP700Z5C booted with Ubuntu Live CD, I did "lsmod | grep -i samsung". Nothing came back! Further, "grep -i samsung /etc/modprobe.d" returned nothing as well. Apparently, 'samsung-laptop' module has not been blacklisted in my Live CD. I am using (uname -a):
Linux ubuntu 3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Steve, what does this all mean? If 'samsung-laptop' module is not loaded by Live CD 12.10 x86_64, then presumably I don't need to install the patched kernel with Colin King's modifications, right?
My understanding is that Secure Boot implies the use of UEFI. While 'samsung-laptop' is not loaded, how safe is it to proceed with Ubuntu installation in Secure Boot mode?
I will be happy to run as many additional checks as necessary before attempting the installation in order to avoid the RMA route.
