Model description

Lenovo ThinkPad X1 Carbon (X1C). There is also a touch version. Comes without optical drive. Has UEFI BIOS with BIOS-legacy fallback mode.

Tip: A great resource for thinkpads is http://www.thinkwiki.org/wiki/ThinkWiki


This procedure is far less involved then UEFI and works perfectly.

In order to turn off UEFI booting you will need to boot into your BIOS and change the boot mode to Legacy. Afterward, follow the Beginner's Guide for standard installation instructions.


See https://bbs.archlinux.org/viewtopic.php?pid=1288500#p1288500

1. You follow the guide from here and skip the part about errors and refind: Create_UEFI_bootable_USB_from_ISO

2. Make sure you USB is mounted to /boot/efi and install grub, like so:

$ grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=arch_grub --boot-directory=/boot/efi/ --recheck --debug

OBS: You can remove the entry from your EFI bootmanger, with efibootmgr by issuing:

$ efibootmgr -b XX -B

3. Now you can choose if you wanna hack you grub.cfg or use the custom config in grub.d. Either way generate the grub.cf:

$ grub-mkconfig -o /boot/efi/grub/grub.cfg

4. Make certain appropriate changes have been made to grub.cfg. My working example, which could use cleaning:

### BEGIN /etc/grub.d/10_linux ###
menuentry 'Arch Linux test'  {
	set gfxpayload=keep
	insmod gzio
	insmod part_gpt
	insmod ext2
	set root='hd0,gpt1'
	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt1 --hint-efi=hd0,gpt1  B35D-FE34
	  search --no-floppy --fs-uuid --set=root B35D-FE34
	echo	'Loading Linux core repo kernel ...'
	linux	/arch/boot/x86_64/vmlinuz root=UUID=B35D-FE34 ro  archisobasedir=arch archisolabel=ARCH_201306
	echo	'Loading initial ramdisk ...'
	initrd	/arch/boot/x86_64/archiso.img

### END /etc/grub.d/10_linux ###

5. Move the grub.efi to overwrite the archiso supplied one (which btw works on my desktop. I guess GRUB includes more workarounds for buggy firmware from manufactureres. See this video, if you have time: http://mjg59.dreamwidth.org/10014.html

$ mv /boot/efi/EFI/arch_grub/grubx64.efi /mnt/efi/EFI/boot/bootx64.efi

Success. Somethings are implied, like GPT partitiontable etc.


Almost everything works out of the box.


Sound works out of the box.



Not tested.


Works out of the box. Uses the following module

  • iwlwifi

lspci output: Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 96)


Works out of the box. Haven't looked for possibilities to configure multi-touch.


The video card installed is Intel HD Graphics 4000

Install the video driver with pacman -S xf86-video-intel

To use SNA acceleration method add

Section "Device"
        Identifier "Intel Graphics"
        Driver "intel"
        Option "AccelMethod" "sna"


Get KMS working by adding i915 to the modules line

$ mkinitcpio -p linux

You also have to enable VT in BIOS.


Works out of the box. Tested with guvcview

Fingerprint Reader

fingerprint-guiAUR from the AUR is already patched to work with the X1's newer fingerprint reader. To get the gui's dropdown to recognize your device, you'll have to add your user to the plugdev group:

$ gpasswd -a <username> plugdev

See fingerprint-gui for more information about config

lsusb output: 147e:2020 Upek TouchChip Fingerprint Coprocessor (WBF advanced mode)

WWAN (Mobile broadband)

This model includes a Ericsson H5321gw adapter that can be used as a mobile broadband adapter and GPS.

The SIM-card must be inserted in the back of the laptop.

Add text to the following file and reboot

options cdc_ncm prefer_mbim=N

Tested OK with networkmanager with modemmanager installed

lsusb output: 0bdb:1926 Ericsson Business Mobile Networks BV


Install gpsd from extra and mbm-gpsd-git from AUR. Add this to the following file

ATTRS{idVendor}=="0bdb", ATTRS{idProduct}=="1926", ENV{ID_USB_INTERFACE_NUM}=="09", ENV{MBM_CAPABILITY}="gps_nmea"
ATTRS{idVendor}=="0bdb", ATTRS{idProduct}=="1926", ENV{ID_USB_INTERFACE_NUM}=="03", ENV{MBM_CAPABILITY}="gps_ctrl"

Reboot to reload udev rules.

Run sudo mbm-gpsd

See if there's GPS-output cat /dev/gps0

Run sudo gpsd -b -N /dev/gps0

To test it xgps

Or use e.g. foxtrotgpsAUR in AUR.

Keyboard backlight

Works out of the box. Use FN+Space


Works out of the box. Test with

$ systemctl start bluetooth
$ bluetoothctl
[bluetooth]# power on
