== Configuration ==
  
While Arch Linux is running flawlessly on this laptop there are a few things you have to configure manually. This article will aid you in configuring your system and will provide additionally hints to make your ThinkPad X200 experience even better.
 
 
==Setup==
 
 
===Wireless===
 
===Wireless===
The ThinkPad X200 has a Intel PRO/Wireless 5100 AGN wireless adapter included. In order to make it work you have to install the iwlwifi-5000-ucode package when you install from a 2010.05 snapshot in order to get the firmware, by now the package is included in the linux-firmware package.
 
  
Now you can choose whatever network configuration programs you want to use. If you do not already know which network manager you want to use, we highly recommend [[netcfg]].
+
The ThinkPad X200 has a Intel PRO/Wireless 5100/5300 AGN wireless adapter, supported by {{Pkg|linux-firmware}}.
  
If you experience connectivity problems such as a slow connection or aborts, especially when connected to an (Enterprise) WPA2 network, then try to load the iwlwifi module with the options {{ic|11n_disable=1}}, {{ic|11n_disable=2}}, {{ic|swcrypto=1}}, {{ic|bt_coex_active=0}}. There is no clear recommendation which of these options to be used as for some users {{ic|11n_disable=1}} already solves the problem sufficiently, for others {{ic|bt_coex_active=0}}. Thus, play around with each of them. Example:
+
If connectivity problems such as a slow connection or aborts are experienced, especially when connected to a [[WPA2 Enterprise]] network, then try to load the iwlwifi module with the options {{ic|11n_disable=1}}, {{ic|11n_disable=2}}, {{ic|swcrypto=1}}, {{ic|bt_coex_active=0}}. There is no clear recommendation which of these options to be used as for some users {{ic|11n_disable=1}} already solves the problem sufficiently, for others {{ic|bt_coex_active=0}}. See [[Wireless network configuration#iwlwifi]] for more detailed instructions.
  
modprobe iwlwifi 11n_disable=2
+
===TrackPoint===
  
If some of them work out for you, then make the options permanent by creating the file {{ic|/etc/modprobe.d/wireless.conf}} and adding the following:
+
See [[TrackPoint]].
  
options iwlwifi 11n_disable=2
+
===Fingerprint Reader===
# Disable blinking LED wireless light
+
options iwlwifi led_mode=1
+
  
===Graphics===
+
Depending on the laptop variant the fingerprint reader in the X200/X200T could be supported.
The graphics card is supported by the xf86-video-intel driver package from the extra repository. The Xorg server makes use of this automatically. There's no need for a Xorg configuration file.
+
  
# pacman -S xf86-video-intel
+
See [[fprint]] for more information.
  
===Audio===
+
===Disable bluetooth at boot===
Audio is supported out of the box after installing the necessary alsa packages from the core repository.
+
  
# sudo pacman -S alsa-lib
+
See [[Power saving#Bluetooth]].
  
See [[Alsa]] for more information.
+
===Hard Disk shock protection===
  
==Configuration==
+
The ThinkPad X200 comes with an integrated 2-axis accelerometer providing the possibility of parking the hard drive's disk heads preventing from data loss due to heavy shocks. See [[HDAPS]] for details. It may be necessary to set correct [[HDAPS#Invert_module_parameter|invert parameter]].
{{note|Useful configuration settings and examples for an X200 are maintained in [https://github.com/orschiro/Linux this] github repo.}}
+
  
===Disable bluetooth at boot===
+
===Mute button===
In order to disable bluetooth at boot you just need to add the following line to a newly created /etc/tmpfiles.d/disable-bluetooth.conf file. Please note, that there is no longer support for a /etc/rc.local file.
+
If the mute button on the keyboard is not working, then be sure to add acpi_osi="Linux" to the boot parameter in /etc/default/grub.
  
  w /proc/acpi/ibm/bluetooth - - - - disable
+
  GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=Linux"
  
===Hard Disk Shock Protection===
+
===Screen calibration===
The ThinkPad X200 comes with an integrated 2-axis accelerometer providing the possibility of parking the hard drive's disk heads preventing from data loss due to heavy shocks.
+
If the stylus happens to be working very imprecisely, the screen may be in need of calibration. Installing {{AUR|xinput_calibrator}} and running the following command will begin the calibration process.
  
First you'll have to install [https://aur.archlinux.org/packages.php?ID=3985 tp_smapi] and [https://aur.archlinux.org/packages.php?ID=5401 hdapsd] from [[AUR]]. Then you have to load the hdaps module provided by tp_smapi with the option invert=5 passed. This will correct the orientation of the accelerometer's axises. If you are using systemd, create a file {{ic|/etc/modules-load.d/tp_smapi.conf}} with the following line:
+
# xinput_calibrator --device "Serial Wacom Tablet WACf004 stylus"
  
# Load tp_smapi at boot
+
To save the calibration settings, create a config file at {{ic|/etc/X11/xorg.conf.d/99-calibration.conf}} with the settings provided by xinput_calibrator.
options tp_smapi invert=7
+
  
Then you need to start the hdapsd daemon:
+
===Loading the correct ICC colour profile===
  
# systemctl enable hdapsd
+
Download [https://github.com/yuvadm/dotfiles/raw/x200s/.color/icc/x200.icc x200.icc] and move it to {{ic|~/.color/icc}}. Load the profile with {{AUR|xcalib}} as follows:
# systemctl start hdapsd
+
  
Now check your log files with {{ic|journalctl}} if you see any parking/unparking entries which indicate that hdapsd is successfully configured.
+
$ /usr/bin/xcalib -d :0 ~/.color/icc/x200.icc
  
For full information see: [[HDAPS]]
+
===Screen rotation===
 +
{{Note| Commands like [[xmodmap]], xev, showkey, dmesg, setkeycodes can help you. See [[Extra keyboard keys]] for details.}}
  
{{Note|If you experience parking / un-parking events when not moving your hard disk, then you might use the wrong invert value. Install and run [[AUR|hdaps-gl]] and check whether it shows your machine in the correct orientation when turning the machine. If not, you need to change the invert value. Alternatively to reloading the module you can also directly write a value between 0 and 7 to {{ic|/sys/devices/platform/hdaps/invert}}.}}
+
The screen rotation hardware button does not work by default. To enable it, the button must first be assigned to a freekey code. To find a free keycode for use, try using the command {{ic|xmodmap -pke <nowiki>|</nowiki> less}}.
  
===Mute button===
+
Keycodes can be mapped to hardware buttons during the boot process via a [[systemd]] config file such as the one shown below.
If the mute button on your keyboard is not working, then be sure to add acpi_osi="Linux" to your boot parameter in /etc/default/grub.
+
  
  GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=Linux"
+
{{hc|head=/etc/systemd/system/setkeycodes.service|output=
 +

 +
 
 +
[Install]
 +
WantedBy=multi-user.target
 +
}}
 +
 
 +
After successfully mapping a keycode to a hardware button, it can then be utilized with a script similar to the one below.
 +
 
 +
{{hc|head=/usr/local/bin/screen_rotation.sh|output=<nowiki>
 +
#!/bin/sh
 +
 
 +
# Find the line in "xrandr -q --verbose" output that contains current screen orientation and "strip" out current orientation.
 +
rotation="$(xrandr -q --verbose | grep 'connected' | egrep -o '\) (normal|left|inverted|right) \(' | egrep -o '(normal|left|inverted|right)')"
 +
 
 +
# Using current screen orientation proceed to rotate screen and input tools.
 +
case "$rotation" in
 +
    normal)
 +
    # rotate to the left
 +
    xrandr -o left
 +
    xsetwacom set "Serial Wacom Tablet WACf004 stylus" rotate ccw
 +
    xsetwacom set "Serial Wacom Tablet WACf004 eraser" rotate ccw
 +
    ;;
 +
    left)
 +
    # rotate to normal
 +
    xrandr -o normal
 +
    xsetwacom set "Serial Wacom Tablet WACf004 stylus" rotate none
 +
    xsetwacom set "Serial Wacom Tablet WACf004 eraser" rotate none
 +
    ;;
 +
esac
 +
</nowiki>}}
 +
 
 +
The assignment of the keycode to the script depends on the currently installed desktop environment. For [[GNOME]], the assignment can be easily done in the custom shortcuts section of the Keyboard preferences.
 +
 
 +
If you are using another desktop environment (such as [[Xfce]], [[LXDE]], [[Fluxbox]], etc) you can always use the program [[xbindkeys]].
 +
 
 +
===Screen auto-rotation===
 +
 
 +
Screen auto-rotation does not work by default. Installing the [[HDAPS]] package will allow for the utilization of the ThinkPad X200's integrated 2-axis accelerometer.
 +
 
 +
After installing HDAPS, the following configuration file may be created to automate screen rotation:
 +
 
 +
{{bc|<nowiki>#!/bin/bash
 +
 
 +
# (To have the exact names of these devices you should type the command : xsetwacom --list devices )
 +
stylus="Serial Wacom Tablet stylus"
 +
eraser="Serial Wacom Tablet eraser"
 +
 
 +
function rotate {
 +
    if [ $# -lt 1 ]; then  # error ...
 +
exit 1
 +
    fi
 +
 
 +
    case "$1" in
 +
        up)
 +
            nextRotate="none"
 +
            nextOrient="normal" ;;
 +
        down)
 +
            nextRotate="half"
 +
            nextOrient="inverted" ;;
 +
right)
 +
            nextRotate="ccw"
 +
            nextOrient="left" ;;
 +
left)
 +
            nextRotate="cw"
 +
            nextOrient="right";;
 +
    esac
 +
 
 +
    # Rotate the screen     
 +
    xrandr -o $nextOrient
 +
 
 +
    # Rotate the tablet                     
 +
    xsetwacom set "$stylus" Rotate $nextRotate
 +
    xsetwacom set "$eraser" Rotate $nextRotate
 +
}
 +
 
 +
while true; do
 +
    # 1) We extract data about the actual position
 +
    position=$(cat /sys/devices/platform/hdaps/position)
 +
    x=$(echo $position | sed -n "s/(\([-0-9]*\),\([-0-9]*\).*)/\1/p") # most of time contained in [350,650]
 +
    y=$(echo $position | sed -n "s/(\([-0-9]*\),\([-0-9]*\).*)/\2/p") # most of time contained in [-650,-350]
 +
 
 +
    # 2) We work out the x value (= left and right inclination) (always between
 +
    if [ $x -lt 400 ]; then
 +
rotate left
 +
    elif [ $x -gt 600 ]; then
 +
rotate right
 +
    fi
 +
   
 +
    # 3) We work out the y value (= front and back inclination)
 +
    if [ $y -gt -400 ]; then
 +
rotate down
 +
    elif [ $y -lt -600 ]; then
 +
rotate up
 +
    fi
 +
 
 +
    # 4) wait before checking the value again
 +
    sleep 0.5
 +
done
 +
</nowiki>}}
 +
 
 +
This script may be executed during startup to further automate the screen rotation process. See [[Autostarting]] for more information on startup automation.
  
 
===Power consumption and fan control===
 
===Power consumption and fan control===
You might notice a beeping whilst your system is running. This is due to missing fan control. Install the [https://aur.archlinux.org/packages/tlp/ tlp] package from AUR to enable extensive fan and power consumption control.
 
  
You can further disable the nmi-watchdog by creating the file {{ic|/etc/tmpfiles.d/disable-nmi-watchdog.conf}} with the following line:
+
{{note|There is a useful [http://orschiro.blogspot.com/2013/06/linux-powersaving-measures.html blog post] describing possible measures to reduce power consumption of a X200T to almost 7 Watt.}}
 +
 
 +
To set up an efficient power saving environment, install the {{Pkg|tlp}} package. A detailed guide how to implement a simplistic power saving environment based upon TLP can be found [http://www.robert.orzanna.de/simplistic-powersaving-with-systemd-service-files-and-udev-rules/ here].
 +
 
 +
Fan-control software can be used to further reduce power consumption. The {{AUR|tpfanco-svn}}{{Broken package link|{{aur-mirror|tpfanco-svn}}}} package from AUR provides a simplistic GTK GUI for setting up fan activation thresholds based upon the X200's multiple hardware sensors.
 +
 
 +
Investigate [[Powertop]] and the {{AUR|powerstat-git}} package from AUR for more information on measuring actual power consumption.
 +
 
 +
See [[Power saving]] for additional tips.
 +
 
 +
===Suspend to RAM / hibernate ===
 +
 
 +
Suspend to ram and hibernation is fully supported. See [[Suspend and hibernate]] for more information.
 +
 
 +
===BIOS WiFi-Whitelist Removal===
 +
{{Warning| Modifying the system's firmware can be rewarding but it is also very dangerous. Proceed with caution.}}
 +
 
 +
Like most ThinkPads, the X200(s) / X200T has an [http://support.lenovo.com/us/en/documents/migr-43693 FCC enforced whitelist] for wireless cards. This means if a third party wireless card is installed via Mini PCIe or PCMCIA slot, the system will not boot. However, there are many individuals who modify and distribute whitelist-free BIOS updates online.
 +
 
 +
The whitelist-free BIOS for the X200(s) can be found [http://forums.mydigitallife.info/threads/5866-LENOVO-(IBM)-Bioses-especially-Thinkpad/page501 here] and the whitelist-free BIOS for the X200T can be found [http://forums.mydigitallife.info/threads/20223-Remove-whitelist-check-add-ID-s-to-break-hardware-restrictions-mod-requests/page338 here].
 +
 
 +
Make sure the BIOS version the system is running matches the cracked version being distributed.
 +
 
 +
For more information about BIOS flashing and system firmware, please see [[Flashing BIOS from Linux]].
 +
 
 +
===Coreboot / Libreboot ===
 +
{{Warning| Modifying the system's firmware can be rewarding but it is also very dangerous. Proceed with caution.}}
 +
 
 +
[http://coreboot.org/ Coreboot] is a fast and flexible open source firmware solution to replace the system BIOS. The ThinkPad X200 is [https://www.fsf.org/news/libreboot-x200-laptop-now-fsf-certified-to-respect-your-freedom fully supported] by Coreboot and good documentation can be found at the Libreboot project's official [http://libreboot.org/ website]. The X200s and X200 Tablet are also partially supported per the [http://www.libreboot.org/docs/hcl/x200.html#x200s Libreboot X200 documentation].
 +
 
 +
For more information on the Libreboot project, see Gluglug's official [http://www.gluglug.org.uk/ website].
 +
 
 +
==Troubleshooting==
 +
 
 +
=== failed to execute '/usr/sbin/inputattach' ===
 +
If you see the above error in your logs, copy {{ic|/usr/lib/udev/rules.d/70-wacom.rules}} to {{ic|/etc/udev/rules.d/70-wacom.rules}} and comment out SUBSYSTEM of inputattach.
 +
 
 +
===System feels unresponsive===
 +
If your system feels unresponsive and lagging, you can try creating a file called {{ic|/etc/modprobe.d/drm_kms.conf}}:
 +
 
 +
options drm_kms_helper poll=N
 +
 
 +
===Backlight fails to activate after system resume ===
 +
On rare occasions the backlight may not activate after resuming. See [http://www.thinkwiki.org/wiki/Problem_with_display_remaining_black_after_resume Problem with display remaining black after resume] for possible workarounds.
 +
 
 +
===PM device: Resume from hibernation error: Failed to restore -19===
 +
 
 +
This is likely to be related to the tpm_tis and tpm modules not being properly unloaded before hibernation. These modules are required by the device listed in the error as 00:0a:
 +
 
 +
# dmesg | grep 00:0a
 +
[    0.377877] pnp 00:0a: Plug and Play ACPI device, IDs PNP0c31 (active)

 +
[  10.866734] tpm_tis 00:0a: TPM is disabled/deactivated (0x6)
 +
 
 +
To unload the module create the following executable file called {{ic|/usr/lib/systemd/system-sleep/tpm.sh}}, assuming the use of the systemd hibernation procedure:
 +
 
 +
#!/bin/sh
 +
case $1/$2 in

Latest revision as of 17:48, 28 May 2016

The Lenovo ThinkPad X200 is a high-quality laptop featuring a 12.1" widescreen WXGA display, an Intel Core 2 Duo processor (2.26 - 2.66GHz), an Intel Graphics Media Accelerator 4500MHD and up to 8GB of RAM whilst still maintaining impressive battery life.

Configuration

Wireless

The ThinkPad X200 has a Intel PRO/Wireless 5100/5300 AGN wireless adapter, supported by linux-firmware.

If connectivity problems such as a slow connection or aborts are experienced, especially when connected to a WPA2 Enterprise network, then try to load the iwlwifi module with the options 11n_disable=1, 11n_disable=2, swcrypto=1, bt_coex_active=0. There is no clear recommendation which of these options to be used as for some users 11n_disable=1 already solves the problem sufficiently, for others bt_coex_active=0. See Wireless network configuration#iwlwifi for more detailed instructions.

TrackPoint

See TrackPoint.

Fingerprint Reader

Depending on the laptop variant the fingerprint reader in the X200/X200T could be supported.

See fprint for more information.

Disable bluetooth at boot

See Power saving#Bluetooth.

Hard Disk shock protection

The ThinkPad X200 comes with an integrated 2-axis accelerometer providing the possibility of parking the hard drive's disk heads preventing from data loss due to heavy shocks. See HDAPS for details. It may be necessary to set correct invert parameter.

Mute button

If the mute button on the keyboard is not working, then be sure to add acpi_osi="Linux" to the boot parameter in /etc/default/grub.

GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=Linux"

Screen calibration

If the stylus happens to be working very imprecisely, the screen may be in need of calibration. Installing xinput_calibratorAUR and running the following command will begin the calibration process.

# xinput_calibrator --device "Serial Wacom Tablet WACf004 stylus"

To save the calibration settings, create a config file at /etc/X11/xorg.conf.d/99-calibration.conf with the settings provided by xinput_calibrator.

Loading the correct ICC colour profile

Download x200.icc and move it to ~/.color/icc. Load the profile with xcalibAUR as follows:

$ /usr/bin/xcalib -d :0 ~/.color/icc/x200.icc

Screen rotation

Note: Commands like xmodmap, xev, showkey, dmesg, setkeycodes can help you. See Extra keyboard keys for details.

The screen rotation hardware button does not work by default. To enable it, the button must first be assigned to a freekey code. To find a free keycode for use, try using the command xmodmap -pke | less.

Keycodes can be mapped to hardware buttons during the boot process via a systemd config file such as the one shown below.

/etc/systemd/system/setkeycodes.service
[Unit]
Description=Assign each hardware button to a free keycode on boot

[Service]
Type=oneshot
ExecStart=/usr/bin/setkeycodes 0x67 184 0x6c 185 0x68 186 0x66 187

[Install]
WantedBy=multi-user.target

After successfully mapping a keycode to a hardware button, it can then be utilized with a script similar to the one below.

/usr/local/bin/screen_rotation.sh
#!/bin/sh

# Find the line in "xrandr -q --verbose" output that contains current screen orientation and "strip" out current orientation.
rotation="$(xrandr -q --verbose | grep 'connected' | egrep -o  '\) (normal|left|inverted|right) \(' | egrep -o '(normal|left|inverted|right)')"

# Using current screen orientation proceed to rotate screen and input tools.
case "$rotation" in
    normal)
    # rotate to the left
    xrandr -o left
    xsetwacom set "Serial Wacom Tablet WACf004 stylus" rotate ccw
    xsetwacom set "Serial Wacom Tablet WACf004 eraser" rotate ccw
    ;;
    left)
    # rotate to normal
    xrandr -o normal
    xsetwacom set "Serial Wacom Tablet WACf004 stylus" rotate none
    xsetwacom set "Serial Wacom Tablet WACf004 eraser" rotate none
    ;;
esac

The assignment of the keycode to the script depends on the currently installed desktop environment. For GNOME, the assignment can be easily done in the custom shortcuts section of the Keyboard preferences.

If you are using another desktop environment (such as Xfce, LXDE, Fluxbox, etc) you can always use the program xbindkeys.

Screen auto-rotation

Screen auto-rotation does not work by default. Installing the HDAPS package will allow for the utilization of the ThinkPad X200's integrated 2-axis accelerometer.

After installing HDAPS, the following configuration file may be created to automate screen rotation:

#!/bin/bash

# (To have the exact names of these devices you should type the command : xsetwacom --list devices )

Power consumption and fan control

Note: There is a useful blog post describing possible measures to reduce power consumption of a X200T to almost 7 Watt.

To set up an efficient power saving environment, install the tlp package. A detailed guide how to implement a simplistic power saving environment based upon TLP can be found here.

Fan-control software can be used to further reduce power consumption. The tpfanco-svnAUR[broken link: archived in aur-mirror] package from AUR provides a simplistic GTK GUI for setting up fan activation thresholds based upon the X200's multiple hardware sensors.

Investigate Powertop and the powerstat-gitAUR package from AUR for more information on measuring actual power consumption.

See Power saving for additional tips.

Suspend to RAM / hibernate

Suspend to ram and hibernation is fully supported. See Suspend and hibernate for more information.

BIOS WiFi-Whitelist Removal

Warning: Modifying the system's firmware can be rewarding but it is also very dangerous. Proceed with caution.

Like most ThinkPads, the X200(s) / X200T has an FCC enforced whitelist for wireless cards. This means if a third party wireless card is installed via Mini PCIe or PCMCIA slot, the system will not boot. However, there are many individuals who modify and distribute whitelist-free BIOS updates online.

The whitelist-free BIOS for the X200(s) can be found here and the whitelist-free BIOS for the X200T can be found here.

Make sure the BIOS version the system is running matches the cracked version being distributed.

For more information about BIOS flashing and system firmware, please see Flashing BIOS from Linux.

Coreboot / Libreboot

Warning: Modifying the system's firmware can be rewarding but it is also very dangerous. Proceed with caution.

Coreboot is a fast and flexible open source firmware solution to replace the system BIOS. The ThinkPad X200 is fully supported by Coreboot and good documentation can be found at the Libreboot project's official website. The X200s and X200 Tablet are also partially supported per the Libreboot X200 documentation.

For more information on the Libreboot project, see Gluglug's official website.

Troubleshooting

failed to execute '/usr/sbin/inputattach'

If you see the above error in your logs, copy /usr/lib/udev/rules.d/70-wacom.rules to /etc/udev/rules.d/70-wacom.rules and comment out SUBSYSTEM of inputattach.

System feels unresponsive

If your system feels unresponsive and lagging, you can try creating a file called /etc/modprobe.d/drm_kms.conf:

options drm_kms_helper poll=N

Backlight fails to activate after system resume

On rare occasions the backlight may not activate after resuming. See Problem with display remaining black after resume for possible workarounds.

PM device: Resume from hibernation error: Failed to restore -19

This is likely to be related to the tpm_tis and tpm modules not being properly unloaded before hibernation. These modules are required by the device listed in the error as 00:0a:

# dmesg | grep 00:0a
[    0.377877] pnp 00:0a: Plug and Play ACPI device, IDs PNP0c31 (active)
[   10.746742] tpm_tis 00:0a: 1.2 TPM (device-id 0x1020, rev-id 6)
[   10.746751] tpm_tis 00:0a: Intel iTPM workaround enabled
[   10.866734] tpm_tis 00:0a: TPM is disabled/deactivated (0x6)

To unload the module create the following executable file called /usr/lib/systemd/system-sleep/tpm.sh, assuming the use of the systemd hibernation procedure:

#!/bin/sh
case $1/$2 in
  pre/*)
    echo "Going to $2..."
    modprobe -r tpm
    modprobe -r tpm_tis
    ;;
  post/*)
    echo "Waking up from $2..."
    modprobe tpm
    modprobe tpm_tis
    ;;
esac

mei_me 0000:00:03.0: suspend

If you are seeing this error, a workaround is to blacklist the mei and mei_me modules. More information can be found here.

pciehp 0000:00:1c.1:pcie04: Cannot add device at 0000:03:00

See #mei_me 0000:00:03.0: suspend.

Uhhuh. NMI received for unknown reason 30.

The Thinkpad X200 is known to report the following error on resume from hibernation or suspension:

Uhhuh. NMI received for unknown reason 30.
Dazed and confused, but trying to continue
Do you have a strange power saving mode enabled?

In this case you can disable the high precision event timer (HPET) by adding "nohpet" to your GRUB kernel parameter line.

High pitched noises

The X200(s) is prone to high pitched, low volume noises originating from the CPU, usually in low power scenarios. One proved solution to this is to disable CPU power control in the BIOS.

High pitched noises may also be emitted from the display's inverter board on CCFL models. This is normal behavior and may or may not be present depending on how much energy the installed display draws.

For more information see [1].
