Samsung Series 7 Chronos Ubuntu Install

[kmas]

This thread was originally started to fix a Samsung Series 7 Chronos boot install. But there's a bunch of other issues I encountered therefore I'm turning this into a general thread for the device issues on Ubuntu.

Boot Issues:
How to boot from USB on a Samsung Series 7 Chronos:
First go into BIOS and enable legacy devices boot. Save changes, reboot, press esc at startup screen, then you should see your USB. If this doesn't work, Make sure you not plugging the USB into the USB 3.0 Port (blue port). If you want that port to work anyways boot into windows, and install the drivers for USB 3.0

How to Boot into Ubuntu on a Samsung Series 7 chronos:
If you already booted into windows and enabled the option to allow you to fast boot into Windows, you just enabled UEFI, and created a gpt partition for booting into machine. Try the troubleshooting steps from here: https://help.ubuntu.com/community/Gr...stalling_GRUB2 , you will most likely have issues and error messages similar to this post and this is why. You can either [disable UEFI from BIOS, use FixParts to remove GPT partition all together] or you can [use Boot Repair CD] or if you feeling like RAMBO [Here is the full UEFI Ubuntu Booting tutorial, This might be helpful skill to know in long run, when we move to Windows 8+ machines]

Drivers Issues
Mouse and Touchpad
11.10:
If you installed 11.10, your mouse is probably detected as a PS2 Generic Mouse. Synclient will show that your drivers are not loaded. Didn't find a fix for it, but here is the thread. The workaround is to install kernel 3.2 and configure your conf.d/
12.04:
If you upgraded from 11.10, you might encounter same issues as 11.10. On a clean install however, your mouse multitouch will work. Here is how to properly configure synclient and here are few tips and this helped a lot, Here you can find what all the synclient options mean.

Graphics Card
Switchable Graphics
Our laptop has switchable graphics that aren't quite optimized yet, Read more about it here. These guys report 3.3 kernel has full hybird graphics functionality. Here is a thread that gives more information.
Drivers
Both 11.10 and 12.04 default drivers work just fine, if you install the ati drivers provided by ubuntu's "additional drivers" program, you probably will end up with no Compiz/GPU. The drivers from the ati website don't work. X will fail to start. just turn off the switchable graphics options previously mentioned with default drivers and you should be fine. In 12.04 you can use Catalyst drivers here's how.


Power Consumption/FAN and Noises
This I got from this post credits to zackrspv and mas
Power:
I tried passing parameters on boot-up (e.g. pcie_aspm=force), but did not help. Utilized powertop, plus juniper as well but could never get power below 28W consumption. Without the tweaks I get around 33W. Getting battery life around 2.5 hours whereas I'm getting 5.5 to 6 hours in Windows 7.
There's a work around on 12.04 that can get you 5 hrs of battery life by using Ati drivers http://ubuntuforums.org/showpost.php...3&postcount=17, suggested by miatawnt2b.

The machine has a SSD and a regular harddisk? If so, wich does the BIOS use to boot?

[kmas]

Oki it looks like it uses the 1TB HDD not the 8GB SSD. at boot when you press escape it doesn't even show any of the SSD. the only bootable hard drive is Samsung-hn-mb101MBB. from a quick google search looks like the 1 TB HDD

I tried to follow the steps to restore GRUB2 on the USB BOOTABLE DRIVE

ubuntu@ubuntu:~$

after reboot it failed like expected GRUB restore didn't work,I then tried another step to force install grub into every partition on my hard drive. There are 2 partitions approx 100MB generated by windows, not sure which one holds the MBR. The force install returns no errors, but after reboot, I get right into windows.

[miegiel]

To start GRUB the ubuntu installation changes the MBR. At one of the last questions during the installation, you are asked if the location the installer found is correct. (something../sda or so)

You could fix it this way (if that's not to daunting).

Never install GRUB to a partition. Always put it on the disk!

So use /dev/sda and not /dev/sda1

here:

sudo grub-setup -d /media/982ce4d5-c8fe-439e-ab77-afc89b20e91a/boot/grub /dev/sda

/dev/sda /dev/sdb are disks and /dev/sda1 /dev/sda2 are partitions on /dev/sda

You're mixing the 2 up when you mount too. It should be:

sudo umount /dev/sda1
sudo mount /dev/sda1 /mnt

[kmas]

I was trying the partition because any attempts to write to the disk won't work. It gave me an error just like the error for the partition. After reading more around I think the root of my problem might be the UEFI enabled on my BIOS. disabling it, and installing Ubuntu will still not let me boot into it, it gives me a black screen.

looks like thse might be the solution. but looks like work i cant complete tonight.

I might be wrong, if you think my assumption is wrong chime in please.

I stepped back and tried what you suggested over again. Here are the results.

Both Proven to be unsuccessful.

Grub used to directly install to a gpt drive, but used blocklists which it does not like. Maybe they have changed it to force the use of a bios_grub partition. I have installed all the newer versions of Ubuntu thru 12.04 to a gpt drive but created the bios_grub 1MB partition first and then had no issues.

Or are you booting in UEFI mode. Is first partition efi? fdisk does not work on gpt use gdisk or parted.

You have to download gdisk from synaptic or apt-get install.
sudo parted /dev/sda unit s print
sudo sfdisk -l -uS
sudo gdisk -l /dev/sda

In a GPT partition map, the 31 kiB area after Master Boot Record where GRUB is usually embedded to, does not exist. When GRUB can't be embedded, its only option is to use blocklists, which are unreliable and discouraged.
However, in the GPT setup, there is no space following the 512-byte MBR for embedding the "second stage" core.img. Thus, you must make a separate "BIOS boot partition" to hold core.img.
BIOS Boot Partition of 1 MiB for partition alignment.

Since the BIOS Boot Partition ("bios_grub" flag set in GNU Parted) is used without a filesystem for storing GRUB 2 boot code "unknown" filesystem! may be shown in many Partition tools.

You can set bios_grub flag in gparted or with command line with gdisk or parted: In GPT fdisk (gdisk), give it a type code of EF02.
sudo parted /dev/sda set <partition_number> bios_grub on

BIOS Boot Partitio only needs to be about 32 KiB in size, although in most cases make it 1 MiB because of partition alignment issues

Since the BIOS Boot Partition ("bios_grub" flag set in GNU Parted) is used without a filesystem for storing GRUB 2 boot code, and since the EFI System Partition (ESP) is used by EFI with a FAT-32 filesystem for storing EFI files, the two cannot be the same partition.
If you're using EFI mode to boot, you don't need a BIOS Boot Partition, but you do need an EFI System Partition (ESP)

If a new drive, to be safe, create both of these partitions, in addition to your regular Linux partitions. But the efi partition has to be the first partition. Do not configure Linux to use either the ESP or the BIOS Boot Partition; they'll be used automatically by GRUB, if necessary.

If you're using EFI mode to boot, you don't need a BIOS Boot Partition with gpt partitions (only for BIOS), but you do need an EFI System Partition (ESP). This is entirely different; it should be a 200-300 MiB FAT32 partition that's flagged as an ESP and must be the first partition. In libparted-based tools, you'd give it a "boot" flag (which is entirely unrelated to the MBR boot/active flag, although libparted makes them look the same). In gdisk, you'd give it a type code of EF00.
An EFI System Partition (~100 to -256MiB, FAT32) for UEFI, a BIOS Boot Partition (~1MiB, no filesystem) for BIOS, and whatever partitions you want for Linux. You must set the partition type codes correctly, but how you do this depends on the utility you use to create them. Also, you should be sure to create a GUID Partition Table (GPT) on the disk, not a Master Boot Record (MBR) partition table. In BIOS mode, Ubuntu's installer defaults to creating MBR partitions, at least on sub-2TB disks, so you may need to use another utility to do the partitioning.

Oki, sorry for late reply. I recieved a replacement unit, because other unit was defective. First thing I notice is that the fdisk gives me a different result.
