Notes

I had troubles to boot a 64 bit system on this laptop, so i stick to a 32 bit system. Will try a 64 bit kernel an report back.

The keys for switching wlan on/off, brightness control, volume control, etc. send just partially unknown keycodes that have to be bound with setkeycode. If you wanna use them as hotkeys for those actions, you've got to tell your window manager to do it (since this are mostly things just root is allowed to do sudo is your friend).

Sleep modes: Suspend to Ram works fine, Suspend to disk not tested due to missing swap partition (Who needs a swap partition with 4 GB of Ram?)

Battery runtime: Around 7 hours, idle, without wlan on.

Backlight Control

Backlight control is working fine since 2.6.39.

Improving Battery Runtime

1. Remove the bluetooth support, if you dont need bluetooth always. You can add hci_usb to the blacklist file of modprobe so the driver doesn't get loaded in the boot process.
2. Because of the glossy display its not possible to work with the laptop at daylight in on of the lower brightness states without getting reflections from everywhere. The limit how much power to save and how many reflections to accept is a personal choice. Maybe its best to work with a very bright ui style.
3. Try powertop to find out what keeps the kernel from sleeping.

Summary

Because most of the parts inside are made by Intel the linux support is pretty good.

Hi, I made an howto to take advantage of the VA-API h264 hardware video acceleration:

Darkbasic, 2012/01/31 18:19

Hi all,
I need to know which distros does include a fix in their kernel patchset to mainline it, so please let me know if you are facing this problem and which distro do you use: https://bugs.freedesktop.org/show_bug.cgi?id=27169 (the console output is not full screen due to spurious S-Video TV detection)

Arch does for sure.

Thanks
darkbasic (at) linuxsystems (dot) it

Matt, 2011/06/15 10:05

Ok, since 2.6.39 everything seems to work very decent. Backlight control is there, the hardware rfkill switch can be controlled and with it the wifi led.

It's a pity that the successor of this laptop is already out…

Darkbasic, 2011/06/15 10:19

You mean series 9?
Anyway, you forgot h.264 gpu-accelerated decoding!
http://cgit.freedesktop.org/libva/log/?h=g45-h264
Still quite slow, but it will become faster.

And the new ultra-fast intel sna acceleration!
http://www.phoronix.com/scan.php?page=news_item&px=OTUyOQ

Unfortunately the most annoying bug is still there:
https://bugs.freedesktop.org/show_bug.cgi?id=27169
If someone can test this patch against a laptop with gm45 and a tv-out connector they will mainline it. I already asked for testers in the intel-gfx mailing list, but nobody answered :(

Matt, 2011/06/15 13:49

You are right about the console. With some kernel versions it works, with some not. Annoying, but just a minor thing.

Everything else is pretty well right now…

Darkbasic, 2011/09/14 11:13

Anyway with linux-2.6.39.x/3.0.4 backlight does not still work properly, see http://linux.derkeiler.com/Mailing-Lists/SuSE/2011-07/msg00303.html
To fix it you need patches, see http://files.linuxsystems.it/samsung-x360/ for the patches I do apply.

Darkbasic, 2012/01/31 12:56

Since kernel 3.2 you only need http://files.linuxsystems.it/samsung-x360/intel_tv-2.6.38.c which hopefully will be mainstreamed soon or later (some distros like Archlinux already have it).

Sam Singer, 2010/03/22 11:34

Hi and thanks, I am running kubuntu amd64 9.10 - and it runs like a charm.

But your xrandr tweak doesnt work here: only values 0-7 are accepted, but no changes.

I also wonder how to address the webcam. It is not shown by lspci:

Hi Sam,

yes,I've noticed that, too. It looks like the xorg developers changed something here.
But with setpci setting the brightness still works, see the comment from darkbasic below.


The webcam is usb powered, try lsusb. It's supported by the uvcvideo module and there should be a device /dev/video0.

Best regards,
Matt

darkbasic, 2010/03/02 16:25

I found a trick to change brightness:

# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset
Integrated Graphics Controller (rev 07)
# setpci -s 00:02.0 F4.B=xx (a value between 00 and FF, where FF is 100%)

Hi,

I own a Samsung X360 AA01PL model. With Fedora 10-11, I have noticed no
mayor problems, even the backlight control was OK (thanks to the
forum!!!).

Unfortunately, with more recent kernels of Fedora 11, as well as under
Fedora 12, I am suffering this very nasty bug:

System works fine as long as it is plugged in, but on battery the system
freezes after some minutes. It seems the problem is related to the
graphics driver. I have tried playing with various kernel parameters
(pci=msi, noapic etc) but not with much success.

      [root@x360 ~]# uname -a
      Linux x360.localdomain 2.6.31.9-174.fc12.i686.PAE #1 SMP Mon Dec
      21 06:04:56 UTC 2009 i686 i686 i386 GNU/Linux


This is pretty disturbing, so I am wonder if anybody else observed this
problem, or have any solution.

For some reasons, I would like to stick to Fedora.

Many thanks!

All the best in the New Year 2010!
Karol Grela

P.S. except this everything works fine: the scanner, external 22”
monitor (even via HDMI), etc. Just this stinky bug ;)

Matt, 2009/12/27 23:08

Hi,

never heard of any problems like yours. Sorry. But how did you get the backlight to work? Or are you just mentioning the hints given above?

Regards,
Matt

Grela, 2009/12/27 23:22

Hi,

the backlight control was via the above described trick, sorry (xrandr -output LVDS –set BACKLIGHT_CONTROL legacy).

So, it seems, that this freezing is only under Fedora. Which distro are you using currently? (I would like to stay with Fedora, but…)

cheers,
Karol

P.S. By the way, Windows people seem to have similar problem: http://forum.notebookreview.com/showthread.php?p=5618245#post5618245

Matt, 2009/12/28 08:57

I'm running Debian Unstable with a costum made kernel. So far no stability problems here. Maybe you should try to boot a live distribution from an USB flash memory and see if the problem remains. If so, then this could be a hardware problem.

Regards,
Matthias

PS: I've got news about the backlight from the kernel devs: http://bugzilla.kernel.org/show_bug.cgi?id=12174

Matt, 2009/07/19 19:56

Has someone got an external monitor running, not as mirror, but as additional screen?

Sergey, 2009/06/17 19:35

Hi,

is there any solution for x64 version? I tried different versions of Ubuntu (from 8.04), I tried Debian… May be there is a special parametr for boot or for bios to be put?

How did you turn off the bluetooth?
And how to turn off the Wi-Fi?

Matt, 2009/06/17 21:17

I'm still running a 32 bit version of debian, if you got any luck please let us know. Maybe you wanna look if there's a new bios version.

For turining off bluetooth it should be enough to unload the module, then the bluetooch device wont be brought up and will consume less power (its still connected, but not transmitting)
If you wanna be able to use bluetooth, but just disable it, have a look at hciconfig and bring hci0 down.

Wifi can be disabled via the rfkill switch of the iwlagn driver.
Just echo 0 > /sys/class/rfkill/rfkill0/state (iirc, I'm not quite sure if this is the right path, but it looks similiar)
to enable it again echo 1.

Hey,
has anyone tested HDMI with this laptop meanwhile?
Thanks, Gerald

Matt, 2009/05/30 12:38

Sorry, not yet. I've got a tv with hdmi input here, but no cable. If i find a cable i will test this soon.

Tom, 2009/07/19 14:16

The HDMI interface works fine at 1920×1200 with an HDMI-DVI cable.

Martin, 2009/01/22 01:29

for the brightness issue check this out: http://ubuntuforums.org/showthread.php?p=6500753

Matt, 2009/01/22 12:40

Hi,
thanks for the link.

Works for me and this line is enough:
xrandr –output LVDS –set BACKLIGHT 100

The BACKLIGHT value is an unsigned integer, so values between 0 and 255 are allowed.

0 means BACKLIGHT is off. 250 full backlight.

Working values are for me:
0, 10, 20, 30, 40, … , 240, 250

Hi,

I took the liberty of creating a Linux Launchpad team for the people who own or develop for the Samsung X360 series laptop, so that we can have more visibility upstream when having to ask for patches or support.

https://launchpad.net/~samsung-x360

I'll be sending a couple of messages to ubuntuforums and notebookreview forums to gather the ~10 users I've identified so far.

Cheers,

Albert.

Matt, 2009/01/02 08:15

Many thanks to Mark H. for the acpidump.

John, 2008/12/11 04:33

Have you had any further success with the backlight issue? It seems I cannot install Linux and get this to work.

Matt, 2008/12/11 12:08

Hi John,
not yet, but i wrote a bug report:
http://bugzilla.kernel.org/show_bug.cgi?id=12174

Currently I'm living without backlight control. I set the brightness i need when i see the grub screen and work then without beeing able to change it. Its a pity, but currently I have no solution for this.

Karol, 2010/02/12 15:37

Hi again!

I've found quick & dirty solution, without replacing Fedora with other distro.

Before working on batteries, it is enough to a) unplug it b) suspend c) wake-up. Voila!

After this “woo-doo” my system works perfectly even on batteries. Stupid… But works.

all the best,
Karol
