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.
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. Run the following commands as root to free up some space.
# First clear the pstore mkdir -p /dev/pstore mount -t pstore pstore /dev/pstore ls /dev/pstore # <- Nothing important should be here, but check first anyway rm /dev/pstore/*
# Next some EFI variables. These are used/created by pstore, but I have had them even though #I deleted the pstore data using the above commands. YMMV. 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, copy the two lines below into a new file:
/etc/udev/hwdb.d/90-libinput-x220-touchpad-fw81.hwdb
touchpad:i8042:* LIBINPUT_MODEL_LENOVO_X220_TOUCHPAD_FW81=1
then run udevadm hwdb --update && udevadm control --reload-rules && udevadm trigger
See Fedora bug #1264453 for more details.
