I have been running Ubuntu 13.04 on SAMSUNG NP530U3C-A05EE for a good week
and a half. So far so good. Please note, that I am running a mainline 3.10
kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/ which among
other things contains Matthew Garrett's UEFI anti-bricking patches.

First of all, I have installed SAMSUNG BIOS upgrades from within Windows 8,
then reduced Windows partition to leave around 40–50 Gb of free space, the
remaining free space on a HDD was allocated for Ubuntu's "/home" directory.
Next I disabled Intel rapid start technology, in Windows, (for I might need
to copy files from Ubuntu to that Windows partition in the future, and
AFAIK having that enabled would lead to filesystem errors) and disabled
secure boot in BIOS. Having made those preparations, I went to install
Ubuntu 13.04 amd64 from a USB flash drive. (I have a 500 Gb hard drive and
a SanDisk SSD i100 24GB. As I do not boot into Windows very often, I wiped
everything wpresent on the SSD and allocated it for Ubuntu's "/" partition
(great boot/app launch speeds!).)

On the first boot I have downloaded a mainline 3.10 (then still RC) kernel,
installed it and rebooted. All is well. Later I realized Windows would not
boot out of the box, complaining something about an invalid path or
something, I do not recall the exect message. However, installing and using
Repair-Boot did the trick; now I am able to boot into both Ubuntu and
Windows 8 just fine.

What works? Pretty much everything. What does not work? Rfkill switch and
fan speed switch (Fn-F11 and Fn-F12 relatively), despite me having
installed the "samsung-tools" package (that's just a frontend) from Voria's
"Samsung on Linux" PPA. I believe both need the functionality the
"samsung-laptop" module provides. However, it is disabled and even though I
took the risk of loading it on my machine (having in mind safety Mr.
Garrett's patches are supposed to provide) I was unable to do that because
of errors.

I wonder will this module be enabled some time in the future. We will see.
