Comment 226 for bug 1040557

So here's my STORY(Long Story) with my Samsung computers.
I think what i'm going to write could be a:

GUIDE IN INSTALLING UBUNTU 12.04.2 ON SAMSUNG 535U3C-A02 AND SAMSUNG 535U3C-A03(A02=AMD A6 - A03=AMD A4)

1) Update BIOS using windows 8(or Win7) preinstalled. My version was P04RAS updated to P07RAS!
2) Create a boot disk using unetbootin on windows 8
3)Go to BIOS>FastBoot>Disabled
4) Go to BIOS>SecureBoot>Disabled>CSM OS(IMPORTANT DO NOT SELECT "CSM OS AND UEFI OS")
5) Select your USB-DRIVE as primary device for boot.
6) Boot into Live.

--BREAK--
At this point the computer should work but there are several problems:
1)Ati drivers(KEEP THE COMPUTER SCREEN ON AND NEVER GO ON SUSPEND..MAYBE CLOSING THE SCREEN OR YOU'LL HAVE TO REBOOT INTO LIVE!!)
2)On AC-plugged in the computer is very slow so please charge your battery before installing. The solution to this problem is installing Jupiter during your live session..so if you install jupiter you can use your computer with AC-in.

--Continue--

7)Install UBUNTU 12.04.2 choosing the option to install Updates and third part software.
8)At this point (for me) WIN 8 is not recognized so chose "Other" in installation option.
9)Editing Partitions:

You just DO NOT TOUCH BOOT PARTIOTION!! Resize Win 8 one(NTFS partition) and create, using the new free space, an EXT4 partition and a SWAP partition. CHOOSE THE HDD(SDA) AS DISK TO INSTALL BOOTLOADER, NO OTHER PARTITION!

10) Let Ubuntu install!
11) On the first reboot install all of the updates needed.
12) After installing updates go to: http://support.amd.com/it/gpudownload/linux/Pages/radeon_linux.aspx and download BETA DRIVERS 13.8!!
13) Install drivers using terminal(go to directory and type "sudo 'name-of-the-driver'")
14) On reboot YOU HAVE YOUR CARD FULLY WORKING AND WAKEUP AFTER SUSPEND WORKS PERFECTLY!!
NOTE:
DO NOT REMOVE THE DRIVER SETUP AFTER INSTALL!! EVERY TIME YOU'LL UPDATE THE KERNEL YOU'LL HAVE TO REINSTALL DRIVERS MANUALLY FROM CONSOLE AND REBOOT. THEN EVERYTHING IS PERFECT AGAIN!

15) INSTALL JUPITER!!! Is very important so that the fan works correctly AND TO SOLVE THE PROBLEM OF SLOW PC ON AC IN!
16) Use the Plymouth fix proposed here: http://www.mobilegeek.it/2010/05/ubuntu-10-04-fix-veloce-per-plymouth/ to make plymouth show correctly on boot!

17) More or less you've DONE!! Enjoy
18) Battery Life is good..3H on 80% charge..
19) Backlight start working when you install ATI drivers.
20) Camera works with skype!

Everything is OK. I use this trick to disable bluetooth on boot: http://www.lffl.org/2011/12/ubuntu-disattivare-il-bluetooth-o-wifi.html

I hope this guide could Help so much people using the same machine. SORRY FOR MY ENGLISH! GOOD LUCK!
