Installation
The X220 can not boot from a GPT disk in Legacy BIOS
mode, it is necessary to either switch to UEFI
booting or create a MBR Partition Table.
Firmware
fwupd does not support this device yet.
To update the firmware on the device, get the latest bootable CD and follow the steps in Flashing BIOS from Linux#Bootable optical disk emulation.
Power management
After waking up the device from suspend, the device might get stuck in a reboot loop. This can be caused by the EFI storage getting too full. To free up some space, clear the pstore:
# mkdir -p /dev/pstore # mount -t pstore pstore /dev/pstore
Nothing important should be here, but check first anyway:
# ls /dev/pstore
Then empty the directory:
# rm /dev/pstore/*
Next some EFI variables. These are used/created by pstore, but everyone should have had them even though the pstore data was deleted using the above commands:
# rm /sys/firmware/efi/efivars/dump-type0-*
Microphone
The internal microphone can generate a lot of static or hissing, the workaround is to mute the right mic input channel.
Touchpad
If the touchpad is jumpy/imprecise, create the following configuration:
/etc/udev/hwdb.d/90-libinput-x220-touchpad-fw81.hwdb
touchpad:i8042:* LIBINPUT_MODEL_LENOVO_X220_TOUCHPAD_FW81=1
Then follow the steps at Map scancodes to keycodes#Using udev.
See Fedora bug #1264453 for more details.
