Lenovo ThinkPad X200
The ThinkPad X200 has a Intel PRO/Wireless 5100/5300 AGN wireless adapter, supported by.
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
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.
Depending on the laptop variant the fingerprint reader in the X200/X200T could be supported.
See fprint for more information.
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.
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.
If the stylus happens to be working very imprecisely, the screen may be in need of calibration. InstallingAUR 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 as follows:
$ /usr/bin/xcalib -d :0 ~/.color/icc/x200.icc
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.
[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.
#!/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.
Power consumption and fan control
To set up an efficient power saving environment, install the here.package. A detailed guide how to implement a simplistic power saving environment based upon TLP can be found
Fan-control software can be used to further reduce power consumption.
Investigate Powertop and the AUR package from AUR for more information on measuring actual power consumption.
See Power saving for additional tips.
BIOS WiFi-Whitelist Removal
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.
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
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.
Libreboot uneven backlight brightness problem
In some CCFL display panel libreboot fails to detect the correct PWM brightness value resulting in uneven backlight (summary). To fix this, you need to flash libreboot version 20210522 or newer (download) (warning libreboot 20210522 has a grub font & restart bug, altough shutdown is okay).
failed to execute '/usr/sbin/inputattach'
If you see the above error in your logs, copy
/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
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_me modules. More information can be found here.
pciehp 0000:00:1c.1:pcie04: Cannot add device at 0000:03:00
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.
