Arthur -- yes, to the best of my knowledge it should be safe to install Ubuntu 12.04 from a latest daily build on your Samsung laptop. These latest builds incorporate the same fix that worked for me.

However, if you want to be completely certain before attempting this potentially risky process, you may want to confirm this with Steve or someone else from Canonical. I am not an employee of Canonical. I do not have the kind of knowledge they do.

To install 12.04, you should set "Secure Mode" to "Off" and "OS Mode Selection" to "UEFI OS". If you want to install from a USB drive, you definitely need to have FastBoot option set to "Off". If you want to install from a CD/DVD, the FastBoot setting is probably irrelevant, but I would still switch it off at least for the installation process. If you have something connected to one of your USB ports during installation, FastBoot must definitely be set to "Off".

There is an ongoing attempt to enable "Secure Boot" for booting both Windows 8 and Ubuntu: http://falstaff.agner.ch/2012/12/18/ubuntu-12-10-and-windows-8-with-secure-boot-mode/ I have not tried it because I don't really need Secure Boot, but if Secure Boot is important to you this page may be your starting point. Good luck!
