How to install Debian Etch on a Samsung M40 XWM 725
So far this laptop works perfectly with a Debian GNU/Linux. There’s just a couple of features which are still disabled:
- TV-Out (shouldn’t be a problem with the nVidia chipset)
- 56k internal modem (appropriate driver seems to be provided)
- MemoryStick card reader (shouldn’t work at all)
- If you find anything wrong in this page (technical or typo…), please feel free to report it to me at julienpauthier at yahoo fr.
If you need information lacking here, maybe you should try to search these websites:

Linux distribution
I installed a Debian Woody 3.0 with bf24 flavor to get the 2.4.18 kernel. Once i got network operational, i dist-upgraded to "Etch" and compiled a 2.6.8 kernel.
UPDATE: i re-installed the system to reorganize the drives a bit, and the Debian 4.0 turns out to work perfectly out-of-the-box (compiz, battery, speedstep… everything is set and works without any source to compile: great!).
Networking
LAN
2.6.x kernels
2.6 kernels offer b44 driver to handle Broadcom network adapter.
2.4.x kernels
When running 2.4.18 kernel, I didn't find any suitable driver, I downloaded the Broadcom driver bcm4400 from their website. Using kernel-headers-2.4.18-bf2.4 package, I recompiled only the driver. Nothing to report: it works properly!
When switching to 2.4.27 Debian kernel, it's possible to use the free driver b44 instead.
Wifi
ipw2200-source Debian package provides sources to build wireless adapter driver. You need to download ipw2200 firmware and untar its content in /usr/lib/hotplug/firmware/ (meaning hotplug package must be installed)
Once module is built, hotplug loads ipw2200 module with required firmware as system boots up. Now iwconfig (provided by wireless-tools package) should get a new network device.
Note: Module (and thus kernel itself) must be built with gcc-3.x to compile ipw2200 module properly.
Graphics
Graphical device
I simply installed nVidia driver (I used version 1.0-6111).
Here is the device section in my X configuration file:
Section "Device"
Identifier "Generic Video Card"
Driver "nvidia"
Option "NoLogo" "on"
BusID "PCI:1:0:0"
EndSection
Monitor
Then configure 17" monitor and add modeline to get 1440x900 resolution:
Section "Monitor"
Identifier "Generic Monitor"
HorizSync 30-64
VertRefresh 50-100
Option "DPMS"
ModeLine "1440x900@60" 97.54 1440 1472 1840 1872 900 919 927 946
EndSection
TV-Out
Here's nVidia documentation concerning TV-Out configuration.
Section "Monitor"
Identifier "TV"
HorizSync 30-50
VertRefresh 60
Option "TVStandard" "PAL-N"
#Option "TVOutFormat" "SVIDEO"
#Option "TVOutFormat" "COMPOSITE"
#Option "ConnectedMonitor" "TV"
EndSection
Input devices
I use the touchpad as well as an USB mouse. Here's the appropriate section needed to handle this properly:
Section "InputDevice"
Identifier "Generic Mouse"
Driver "mouse"
Option "Device" "/dev/input/mice"
Option "Protocol" "ImPS/2"
Option "Emulate3Buttons" "true"
Option "ZAxisMapping" "4 5"
EndSection
So far I didn't experience any problem using touchpad with regular mouse drive. Maybe it'd be better to use Synaptic package...
Note: When switching to kernel 2.6.8, touchpad's scroll aptitude wasn't operational anymore. To get this behavior back, I simply add proto=imps option for psmouse module.
Power management
ACPI
The DSDT is bugged. So I looked at this awesome tutorial describing how to detect and fix a DSDT.
Dumping and fixing DSDT
Once the buggy DSDT (dsdt_buggy.dsl) has been grabbed from /proc/acpi/dsdt and decompiled with iasl, here's the iasl output:
Intel ACPI Component Architecture ASL Optimizing Compiler / AML Disassembler version 20041203 [Dec 3 2004] Copyright (C) 2000 - 2004 Intel Corporation Supports ACPI Specification Revision 2.0c dsdt.dsl 312: Method (_WAK, 1, NotSerialized) Warning 2026 - ^ Reserved method must return a value (_WAK) dsdt.dsl 2575: Field (ECR, DWordAcc, Lock, Preserve) Error 1048 - ^ Host Operation Region requires ByteAcc access dsdt.dsl 2621: Method (_GLK, 1, NotSerialized) Warning 2024 - ^ Reserved method has too many arguments ( _GLK requires 0) ASL Input: dsdt.dsl - 3817 lines, 128061 bytes, 1825 keywords Compilation complete. 1 Errors, 2 Warnings, 0 Remarks, 423 Optimizations
Thanks to the tutorial, it's easy to get a 'fixed' one: dsdt.dsl
Here's the iasl output after a few tweaks:
Intel ACPI Component Architecture ASL Optimizing Compiler / AML Disassembler version 20041203 [Dec 3 2004] Copyright (C) 2000 - 2004 Intel Corporation Supports ACPI Specification Revision 2.0c ASL Input: dsdt.dsl - 3819 lines, 128079 bytes, 1826 keywords AML Output: DSDT.aml - 14834 bytes 492 named objects 1334 executable opcodes Compilation complete. 0 Errors, 0 Warnings, 0 Remarks, 425 Optimizations
Note: I couldn't manage to compile iasl with provided sources. So I simply downloaded win32 binary and ran it using regular wine from Debian repository (yes, I do feel shameful).
Patching kernel
As explained in the tutorial, I patched the kernel and added fixed DSDT file dsdt_table.h (HEX format generated by iasl) in include/acpi/. But, since the provided acpi_patch_2.4.23.diff is meant for 2.4.23, I didn't use patch command and updated file drivers/acpi/osl.c manually (there're only a few lines to update...).
Then, I simply compiled the 2.4.27 kernel. Here is the kernel configuration file I used: kernel config file (2.4.27).
Finally, I can access battery, thermal information... through appropriated ACPI modules. ACPI-linked buttons (battery level on screen display, disable touchpad...) work as well. The box also shutdowns properly. You can now bind power button to shutdown command by installing acpid.
Speedstep
Well... it's time to switch to a 2.6 kernel, if it's not already done! First you have to patch file drivers/acpi/osl.c in the same way, and to add dsdt_table.h in include/acpi/ to override BIOS DSDT with a 'fixed' one.
Patching kernel for Dothan CPU
Then compiling the kernel would work, but speedstep-centrino module wouldn't be loadable ("No such device"). Here's explained how to fix this issue. You just have to patch arch/i386/kernel/cpu/cpufreq/speedstep-centrino.c by replacing :
static const struct cpu_id cpu_id_dothan_a1 = {
.x86_vendor = X86_VENDOR_INTEL,
.x86 = 6,
.x86_model = 13,
.x86_mask = 1,
};
with:
static const struct cpu_id cpu_id_dothan_a1 = {
.x86_vendor = X86_VENDOR_INTEL,
.x86 = 6,
.x86_model = 13,
.x86_mask = 6,
};
According to this page, new 6 value stands for stepping value provided by cat /proc/cpuinfo:
processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 13 model name : Intel(R) Pentium(R) M processor 1.60GHz stepping : 6 cpu MHz : 1595.868 cache size : 2048 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr mce cx8 apic sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss tm pbe tm2 est bogomips : 3162.11
Making CPU silent
I noticed that CPU produced a weird noise when running on its battery and decreasing speed. There's a patch for this in kernel bug tracker. It consists of changing HZ value in file include/asm-i386/param.h from:
#ifdef __KERNEL__ # define HZ 1000 /* Internal kernel timer frequency */ # define USER_HZ 100 /* .. some user interfaces are in "ticks" */ # define CLOCKS_PER_SEC (USER_HZ) /* like times() */ #endif
to:
#ifdef __KERNEL__ # define HZ 100 /* Internal kernel timer frequency */ # define USER_HZ 100 /* .. some user interfaces are in "ticks" */ # define CLOCKS_PER_SEC (USER_HZ) /* like times() */ #endif
Building kernel
Here is the config file I used: kernel config file.
After reboot, speedstep-centrino module should now be loadable (then acpi doesn't need to be loaded anymore since speedstep-centrino replaces it). Then install cpufreqd to let kernel decrease CPU frequency when appropriated!
Sound
OSS
Well, module i810_audio (needs ac97_codec) works properly if you want to listen a few audio files.
Since there's no mixer support, some softwares can't use sound with this device. So I guess it's better to switch quickly to ALSA...
ALSA
I simply compiled ALSA from Debian package alsa-source for 2.4.27 kernel ; for 2.6.8 of course I used ALSA modules from kernel's source.
Once ALSA is properly installed, load modules snd-ac97-codec, snd-intel8x0, snd-intel8x0m.
Hotkeys
I simply read hotkey's codes using xev. Then I could either use hotkeys (providing some cool OSD features) or xmodmap.
Using hotkeys...
When running 2.4 kernel, I installed hotkeys package to handle special keyboard buttons (browser, email client, volume "Fn" keys...) with newly created file /usr/share/hotkeys/samsung.def:
<?xml version="1.0"?>
<definition>
<config model="Samsung M40">
<Play keycode="124"/>
<VolUp keycode="176" adj="2"/>
<VolDown keycode="174" adj="2"/>
<Mute keycode="160"/>
<WebBrowser keycode="125"/>
<Email keycode="128"/>
</config>
<contributor>
<name>Julien Pauthier</name>
<email>julienpauthier at yahoo fr</email>
</contributor>
</definition>
Please note that Play entry is linked to the custom button which is at the same place than email and browser keys on the keyboard.
That's it! Type this to get hotkeys operational:
/usr/bin/hotkeys -Z -t samsung
Using xmodmap...
2.4.x kernels
Here is the .xmodmaprc file:
keycode 128 = XF86Mail keycode 125 = XF86WWW keycode 124 = XF86AudioMedia keycode 160 = XF86AudioMute keycode 176 = XF86AudioRaiseVolume keycode 174 = XF86AudioLowerVolume
Then launch xmodmap (use your ~/.xsession file for example):
/usr/bin/X11/xmodmap .xmodmaprc
You can now capture these keycodes and bind them with any application through your windowmanager's configuration tool.
2.6.x kernels
I couldn't use browser and custom button when running 2.6.8 kernel. I got this error message when I pressed one of these buttons:
atkbd.c: Unknown key released (translated set 2, code 0x74 on isa0060/serio0). atkbd.c: Use 'setkeycodes 74 <keycode>' to make it known. atkbd.c: Unknown key released (translated set 2, code 0x75 on isa0060/serio0). atkbd.c: Use 'setkeycodes 75 <keycode>' to make it known.
This problem is explained (and resolved) here.
So, I added a script in init.d/ that is launched when my laptop boots up:
#! /bin/sh
NAME=sethotkeys
DESC="Setting key codes"
set -e
case "$1" in
start)
echo -n "$DESC... "
/usr/bin/setkeycodes 74 200
/usr/bin/setkeycodes 75 218
echo "done."
;;
*)
N=/etc/init.d/$NAME
echo "Usage: $N {start}" >&2
exit 1
;;
esac
exit 0
Note: I chose keycodes 200 and 218 because they don't match any key I use on my keyboard (see include/linux/input.h).
Then I slightly updated .xmodmaprc file according to new codes captured by xev:
keycode 128 = XF86Mail keycode 194 = XF86WWW keycode 168 = XF86AudioMedia keycode 160 = XF86AudioMute keycode 176 = XF86AudioRaiseVolume keycode 174 = XF86AudioLowerVolume
Now hotkeys work properly with 2.6 kernel!
Modem
According to several reports seen on tuxmobil.org, this internal 56k modem would be supported by slmodem driver provided by SmartLink.
MemoryStick card reader
I haven't tested yet since I don't have any Sony camera. But according to many reports I could read, it seems pretty hard to make that kind of stuff working since there's no driver available for Linux kernels.
